The climate crisis is poised to deliver a severe blow to America’s most threatened animals, with a new study finding that almost every species considered endangered is vulnerable in some way to global heating. Of the 459 animal species listed as endangered by the US government, researchers found that all but one, or 99.8%, have characteristics that will make it difficult for them to adapt to rising temperatures. The California condor, once close to being completely wiped out, faces increased risk of contamination in hotter conditions. Key deer, found only in the Florida Keys, face losing habitat to the rising seas. Whole classes of animals including amphibians, mollusks and arthropods are sensitive to the greatest number of climate-related threats, such as changes in water quality, shifting seasons and harmful invasive species that move in as temperatures climb. Mammals, such as the north Atlantic right whale and Florida panther, also face increased hardships, albeit on fewer fronts than amphibians, mollusks and arthropods.  Despite the overwhelming peril faced by America’s endangered species due to the climate crisis, the report, published in Nature Climate Change, found a patchy response from the US government. Federal agencies consider just 64% of endangered species to be threatened by the climate crisis, while just 18% of listed species have protection plans in place. Astrid Caldas, a study co-author and a climate scientist at the Union of Concerned Scientists said: “While agencies have increasingly listed climate change as a growing threat to species whose survival is already precarious, many have not translated this concern into tangible actions, meaning a significant protection gap still exists.” Nearly half of Australian species are threatened by the climate crisis, researchers have found. A spokesman for the US Fish and Wildlife Service, which oversees the endangered species list, said that while a species may be sensitive to changes in the climate, this sensitivity may not be so severe as to warrant being put on the list. “Our process for determining this looks at five factors: threats to a species’ habitat, overutilization, disease or predation, existing regulatory mechanisms, and other factors that may affect its continued existence,” he said. “Through this scientifically rigorous process we examine and account for the effects of climate change.

Read the following passage and choose the best answer (A, B, C, D):
Thunderstorms, with their jagged bursts of lightning and roaring thunder, are actually one of nature’s primary mechanisms for transferring heat from the surface of the earth into the atmosphere. A thunderstorm starts when low-lying pockets of warm air from the surface of the earth begin to rise. The pockets of warm air float upward through the air above that is both cooler and heavier. The rising pockets cool as their pressure decreases, and their latent heat is released above the condensation line through the formation of cumulus clouds. What will happen with these clouds depends on the temperature of the atmosphere. In winter, the air temperature differential between higher and lower altitudes is not extremely great, and the temperature of the rising air mass drops more slowly. During these colder months, the atmosphere, therefore, tends to remain rather stable. In summer, however, when there is a high accumulation of heat near the earth’s surface, in direct contrast to the considerably colder air higher up, the temperature differential between higher and lower altitudes is much more pronounced. As warm air rises in this type of environment, the temperature drops much more rapidly than it does in winter; when the temperature drops more than 4 degrees Fahrenheit per thousand feet of altitude, cumulus clouds aggregate into a single massive cumulonimbus cloud, or thunderhead. In isolation, a single thunderstorm is an impressive but fairly benign way for Mother Earth to defuse trapped heat from her surface; thunderstorms, however, can appear in concert, and the resulting show, while extremely impressive, can also prove extraordinarily destructive. When there is a large-scale collision between cold air and warm air masses during the summer months, a squall line, or series of thunderheads, may develop. It is common for a squall line to begin when an advancing cold front meets up with and forces itself under a layer of warm and moist air, creating a line of thunderstorms that races forward at speeds of approximately forty miles per hour. A squall line, which can be hundreds of miles long and can contain fifty distinct thunderheads, is a magnificent force of nature with incredible potential for destruction. Within the squall line, often near its southern end, can be found supercells, long-lived rotating storms of exceptional strength that serve as the source of tornadoes.

With 13,000 floral species and over 15,000 faunal species, three newly discovered big animal species, and a ratio of country/world species of 6.3%. Vietnam has enormous tourismparticularly ecotourism-potential. In fact, since 1986, when Renovation Reforms began the shift from a centrally planned to a socialist-oriented market, or multi-sectoral, economy, tourism has been an sector of primary concern to the government. In May 1995, the prime minister of Vietnam approved a master plan of tourism development for the period 1995- 2010. In February 1999, the state decree on tourism was part of the socio-economic development strategy for the period 2001-2010 approved at the IX National Congress of the Party: “Tourism development has become a spearhead economic industry indeed. It is necessary to improve the quality and effectiveness of tourism activities, bringing into full play the natural conditions, and cultural and historical tradition to meet the domestic and international demand for tourism and to catch up with tourism development in the region” (Document of the IX National Congress 2001). Tourism has so far brought great benefits to the economy, but it has also contributed to environmental degradation, especially biodiversity deterioration. Thus, the concept of “sustainable development”-development which meets the needs of the present without compromising the ability of future generations to meet their own needs - must be factored into tourism development. This consideration is reflected in the term “ecotourism,” which is referred to variously as ecological or environmental tourism, nature or green tourism, sustainable or responsible tourism. Ecotourism involves travel to relatively undisturbed natural areas with the specific object of studying, admiring, and enjoying scenery, plants, and animals, as well as any cultural features found in these areas. It is distinguished from mass or resort tourism by its lower impact on the environment, lower infrastructure requirements, and its role in educating tourists about natural environments and cultural values. Fully aware of its significance, the government of Vietnam has prioritized ecotourism in its strategy for tourism development to ensure both sustainability and economic benefits. Though ecotourism in Vietnam is at a beginning stage of development, it is expected to grow strongly through support from government and international organizations.

Urban development is having a direct impact on the weather in (1) ______ cities worldwide. It has been noticed that the difference in temperature is usually greater at night and the phenomenon occurs in both winter and summer. Experts agree that this is due to urban development, when open green spaces are replaced with asphalt roads and tall brick or concrete buildings. These materials retain heat generated by the Sun and release it through the night. In Atlanta, in the US, this has even led to thunderstorms (22) ______ occur in the morning rather than, as is more common, in the afternoon. Large cities around the world are adopting strategies to combat this issue, (3) ______ it is not uncommon to find plants growing on top of roofs or down the walls of large buildings. In Singapore, the government has (4) ______ to transform it into a "city within a garden" and, in 2006, they held an international competition calling for entries to develop a master plan to help bring this about. One outcome was the creation of 18 "Supertrees" – metal constructions resembling very tall trees. Each one is a vertical freestanding garden and is (5) ______ to exotic plants and ferns. They also contain solar panels used to light the trees at night and also containers to collect rainwater, making them truly self-sufficient

Read the following passage and choose the best answer (A, B, C, D):
If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the plants, without whose prior invasion of the land, none of the other migrations could have happened. Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches. There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of he dinosaurs, with
fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.

Language preservation is the effort to prevent languages from becoming unknown. A language is at (1)______ of being lost when it no longer is taught to younger generations, while fluent speakers of the language (usually the elderly) die. Language is an important part of any society, because it enables people to communicate and express themselves. When a language dies (2)_______, future generations lose a vital part of the culture that is necessary to completely understand it. This makes language a vulnerable aspect of cultural heritage, and it becomes especially important to (3) __________ it. According to the United Nations Educational, Scientific, and Cultural Organization (UNESCO), from facts published in their “Atlas of Languages in Danger of Disappearing,” there are an estimated 6,000 languages spoken worldwide today, and half of the world’s population speaks the eight most common. More than 3,000 languages are reportedly spoken by fewer than 10,000 people each. Ethnologue, a reference work published by SIL International, has cataloged the world’s known (4)_______ languages, and it estimates that 417 languages are on the verge of extinction. There are different factors that can (5)________ a language in danger of becoming extinct. One is when a language is no longer being taught to the children of the community, or at least to a large number of the children. In these cases, the remaining fluent speakers of the language are generally the older members of the community, and when they pass away, the language dies out with them

Zoos used to be primarily a place for people to see wild animals they had never seen.  Now, however, zoos serve a new purpose – to be captive-breeding programs for endangered animals. There are less than a hundred Sumatran rhinos worldwide, and three were born in Cincinnati Zoo. When old enough, one of the males was sent to Way Kamabas National Park in Sumatra and this helped to start the process of re-populating his species in the wild and saving it from the extinction.  Other zoos have started captive-breeding programs as well. Zoos have saved the Arabian onyx, the black-footed ferret, the red wolf, the Guam rail, and the California condor. But the cost of the programs for saving the threatened animals is not cheap. The condor program alone costs up to $2 million a year. While it is mostly large-city zoos involved in captive breeding, smaller zoos do their part. The Miller Park Zoo in Bloomington, Illinois, is working on breeding the endangered, and small. Mount Graham red squirrel.  Zoos have always been involved in animal conservation to some degree, but the question of which animals to save is a big one. Endangered animals may not be the most exciting to see in a zoo, and to di conservation work the zoos must survive financially. Space is a problem as well. A zoo might be able to save a small number of large animals or a large number of small ones. Currently, the most threatened group of animals is amphibians. Zoos realize that visitors may not want to see frogs, salamanders, or other small animals and may only pay to see rhinos, lions, and tigers. Some scientists believe zoos should be less tourist attractions and more conservation sanctuaries. Thus, although zoos continue to do good work, they still confront tricky questions. There are a limited number of animals that can be cared for in zoos, and that means many species on the edge of extinction may not survive. The Sumatran orangutan and a thousand other threatened species have not made it into a captive-breeding program, but the species will continue to exist. How? In the Frozen Zoo. Cells from these animals are stored in the San Diego Zoo Institute for Conservation Research in liquid nitrogen. Only one animal in the Frozen Zoo is presently extinct, but many others are at dire risk. In the Frozen Zoo, however, the cells of animals will be preserved for study through their genetic material.

Is cake a socially awkward person’s reward for having made it through the birthday celebration ritual? Well, not exactly. And actually celebrating the anniversary of one’s birth has not always been the done thing either. What if I told you that having your birthday celebrated is the closest you are getting to be a god(dess)? The first “birthday” celebration goes back to the Egyptians who, each year, would rejoice on the anniversary of the pharaoh’s coronation day. The reason being that you were not really born until you were made into a pharaoh, i.e., after you were transformed into a God. From there, the Greeks contributed to bringing a moon-shaped cake and candles to celebrate the lunar goddess, Artemis, to represent the radiance of the moon and her beauty. But still, what about the cake? We have to thank the Germans for introducing the contemporary birthday celebrations, which included a cake. They started the ‘kinderfeste’, where children were honoured with a celebration on their birthday, especially when it came to the first birthday. Kids also had candles on their cake; one for each year they had been alive, plus one, symbolising the chance of making it through the coming year. Fortunately, we now live at a time where birthday cakes come in various shapes, colours and flavours to please different preferences and dietary requirements, as it is very difficult to imagine a birthday party without a sweet and yummy, treat. Conversely, cake eating is less and less reserved to birthdays only, and personally I really like being able to enjoy a piece of cake whenever I feel like it outside birthday parties. Still, there is something even more special about a birthday cake; it is also about sharing special moments with loved ones

Vocational training in the UK is intended to give people the skills and knowledge they  need to perform a particular job, and involves practical instruction as well as theory. Most vocational training takes place not in universities but in colleges of further education and in colleges specializing in art, accountancy, etc. some secondary schools now also offer an introduction to vocational training.  NVQs (National Vocational Qualifications) are qualifications that can be obtained by people already working in a particular industry. Colleges of further education run courses to provide a theoretical background. NVQs are awarded on the basis of practical work, spoken and written test, and coursework. There are five levels, from Foundation to Management. Since 1992 many students in schools and colleges have been working for GNVQs (General National Vocational Qualifications), as an alternative to GCSEs and A levels. GNVQs cover similar areas to NVQs and are intended as introductions to a particular field of work and the skills required. Students can choose from over 500 subjects. At the lowest of its three levels foundation, a GNVQ is equivalent to a GCSE and from 2002 they are being replaced by new vocational GCSEs.  In the US there are no national qualifications like NVQs, though some professional organizations decide on their own qualifications and some of these have become widely accepted. Much vocational training is done by private institutions which are sometimes called proprietary schools. Although many of these are good, in general they have a bad reputation. This is partly because there are no controls over who can operate such a school. Some proprietary schools try to get as many students as possible, including some who will probably not be able to complete their training.  Most US secondary schools programs do not provide a choice between an academic and a practical track (a program of study), but most do give students an opportunity to take some practical or vocational classes. Large school districts may have magnet schools, schools that attract students with certain interests, and some of these may have a large choice of vocational courses.  
3. Which of the following statements is NOT true according to the passage?

Most Americans still get married at some point in their lives, but even that group is shrinking. Among current generations of adult American - starting with those bom in 1920s - more than 90 percent have married or will marry at some point in their lives. However, based on recent patterns of marriage and mortality, demographers calculate that a growing share of the younger generations are postponing marriage for so long that an unprecedented number will never marry at all.

More Americans are living together outside of marriage. Divorced and widowed people are waiting longer to remarry. An increasing number of single women are raising children. Put these trends together with our increasing life expectancy, and the result is inevitable. Americans are spending a record low proportion of their adult lives married.

Married rates for unmarried men and women have dropped from their post-195Os high to record lows. Part of this fall is due to the change in the age at which people first marry. The median age at first marriage is the age by which half the men or women who will ever marry have done so. It fell almost continuously from the time it was first measured, in 1890, at 22.0 years for women and 26.1 for men, to a low of 20.3 for women and 22.6 for men between 1947 and 1962. Since then, it has risen at a rapid pace, to a record high for 23.8 for women and 26.2 for men in 1994.

The length of time between marriages is also increasing, and more divorced people are choosing not to remarry. In 1990, divorced men had waited an average of 3.8 years before remarrying, and divorced women had waited an average of 3.5 years, an increase of more than one year over the average interval in 1970.

Data on cohabitation and unmarried childbearing suggest that marriage is becoming less relevant to Americans. 2.8 million of the nation's households are unmarried couples, and one-third of them are caring for children, according to the Census Bureau

After years of hype and false starts, the shift to clean power has begun to accelerate at a pace that has taken the most experienced experts by surprise. Even leaders in the oil and gas sector have been forced to confront an existential question: will the 21st century be the last one for fossil fuels? It is early, but the evidence is mounting. Wind and solar parks are being built at unprecedented rates, threatening the business models of established power companies. Electric cars that were hard to even buy eight years ago are selling at an exponential rate, in the process driving down the price of batteries that hold the key to unleashing new levels of green growth. “This clean energy disruption has just started and what is striking is how much of a financial impact it is already having on some companies,” says Per Lekander, a portfolio manager at London’s Lansdowne Partners hedge fund, who has tracked global energy markets for more than 25 years. “It hit the electricity sector first, in Europe in 2013 and then the US two years later. Now it has spread to the auto sector and I think the oil industry is next.” The shift has come as increased government efforts to curb climate change and smog have driven down costs and spurred technical advances, creating a green energy industry that looks nothing like it did a decade ago: expensive and sluggish. Today, China and India have picked up the baton and are driving a sector that has spread to every continent. The result was a banner year for green energy in 2016

Andrew Jackson Beard lived an extraordinary life for a black American inventor. Unlike the vast majority of inventors who never profit from their patents, he profited from his inventions. Andrew Beard was born a slave on a plantation in Woodland, Alabama, in 1849, shortly before slavery ended. He received emancipation at age 15 and he married at age 16. Andrew Beard was a farmer, carpenter, blacksmith, a railroad worker, a businessman and finally an inventor. He grew apples as a farmer near Birmingham, Alabama for five years before he built and operated a flour mill in Hardwicks, Alabama. His work in agriculture led to tinkering with improvement for plows. In 1881, he patented his first invention, an improvement to the double plow, and sold the patent rights for $4,000 in 1884. His design allowed for the distance between the plow plates to be adjusted. That amount of money would be the equivalent of almost $100,000 today. In 1887, Andrew Beard patented a second plow and sold it for $5,200. This patent was for a design that allowed the pitch of the blades of plows or cultivators to be adjusted. The amount he received would be the equivalent of about $130,000 today. In 1897, Andrew Beard patented an improvement to railroad car couplers. His improvement came to be called the Jenny Coupler. It was one of many that aimed to improve the knuckle coupler patented by Eli Janney in 1873 (patent US138405). The knuckle coupler did the dangerous job of hooking railroad cars together, which formerly was done by manually placing a pin in a link between the two cars. Beard, himself had lost a leg in a car coupling accident. As an ex-railroad worker, Andrew Beard had the right idea that probably saved countless lives and limbs. Beard received three patents for automatic car couplers. These are US594059 granted November 23, 1897, US624901 granted May 16, 1899, and US807430 granted on May 16, 1904. While there were thousands of patents filed at the time for car couplers, Andrew Beard received $50,000 for the patent rights to his Jenny coupler. This would be just shy of 1.5 million dollars today. Congress enacted the Federal Safety Appliance Act at that time to enforce using automatic couplers. Andrew Jackson Beard was inducted into the National
Inventors Hall of Fame in 2006 in recognition of his revolutionary Jenny coupler

Read the following passage and choose the best answer (A, B, C, D):
Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described. Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both colloquial usage and slang are more common in speech than writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard", "colloquial", and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use three types of expressions.
7. The word "them" in paragraph 3 refers to .

Read the following passage and choose the best answer (A, B, C, D):
Deforestation has important global consequences. Forests sequester carbon in the  form of wood and other biomass as the trees grow, taking up carbon dioxide from the atmosphere. When forests are burned, their carbon is returned to the atmosphere as carbon dioxide, a greenhouse gas that has the potential to alter global climate, and the trees are no longer present to sequester more carbon.  In addition, most of the planet’s valuable biodiversity is within forests, particularly tropical ones. Moist tropical forests such as the Amazon have the greatest concentrations of  animal and plant species of any terrestrial ecosystem; perhaps two-thirds of Earth’s species live only in these forests. As deforestation proceeds, it has the potential to cause the extinction of increasing numbers of these species.  On a more local scale, the effects of forest clearing, selective logging, and fires interact. Selective logging increases the flammability of the forest because it converts a closed, wetter forest into a more open, drier one. This leaves the forest vulnerable to the accidental movement of fires from cleared adjacent agricultural lands and to the killing effects of natural droughts. As wildfires, logging, and droughts continue, the forest can become progressively more open until all the trees are lost. Additionally, the burning of tropical forests is generally a seasonal phenomenon and can severely impact air quality. Record-breaking levels of air pollution have occurred in Southeast Asia as the result of burning for oil palm plantations.  In the tropics, much of the deforested land exists in the form of steep mountain hillsides. The combination of steep slopes, high rainfall, and the lack of tree roots to bind the soil can lead to disastrous landslides that destroy fields, homes, and human lives. With the significant exception of the forests destroyed for the oil palm industry, many of the humid forests that have been cleared are soon abandoned as croplands or only used for lowdensity grazing because the soils are extremely poor in nutrients. The vegetation that contains most of the nutrients is often burned, and the nutrients literally “go up in smoke” or are washed away in the next rain. Although forests may regrow after being cleared and then abandoned, this is not always the case, especially if the remaining forests are highly fragmented. Such habitat fragmentation isolates populations of plant and animal species from each other, making it difficult to reproduce without genetic bottlenecks, and the fragments may be too small to support large or territorial animals. Furthermore, deforested lands that are planted with commercially important trees lack biodiversity and do not serve as habitats for native plants
and animals, many of which are endangered species.
6. Paragraph 4 mentions all of the following information EXCEPT ______

Biofuels and the Environment

Leading investors have joined the growing chorus of concern about governments and companies rushing into producing biofuels as a solution for global warming, saying that many involved in the sector could be jeopardizing future profits if they do not consider the long-term impact of what they are doing carefully.

It is essential to build sustainability criteria into the supply chain of any green fuel project in order to ensure that there is no adverse effect on the surrounding environment and social structures. The report produced by the investors expresses concern that many companies may not be fully aware of the potential pitfalls in the biofuel sector.

Production of corn and soya beans has increased dramatically in the last years as an eco-friendly alternative to fossil fuels but environmental and human rights campaigners are worried that this will lead to destruction of rain forests. Food prices could also go up as there is increased competition for crops as both foodstuffs and sources of fuel. Last week, the UN warned that biofuels could have dangerous side effects and said that steps need to be taken to make sure that land converted to grow biofuels does not damage the environment or cause civil unrest. There is already great concern about palm oil, which is used in many foods in addition to being an important biofuel, as rain forests are being cleared in some countries and people driven from their homes to create palm oil plantations.

An analyst and author of the investors' report say that biofuels are not a cure for climate change but they can play their part as long as governments and companies manage the social and environmental impacts thoroughly. There should also be greater measures taken to increase efficiency and to reduce demand.

Biofuels might______

Herman Melville, an American author best known today for his novel Moby Dick, was actually more popular during his lifetime for some of his other works. He traveled extensively and used the knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849). In 1841, Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered around the islands of Tahiti and Moorea.This South Sea island sojourn was a backdrop to the novel Omoo (1847). After three years awayfrom home, Melville joined up with a U.S. naval frigate that was returning to the eastern United States around Cape Horn. The novel White Jacket (1850) describes this lengthy voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of humanity against the universe. The public was not ready for Melville's literary metamorphosis from romantic adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's popularity during his lifetime is the one for which he is best known today.
