Although only a small percentage of the electromagnetic radiation that is emitted by the Sun is ultraviolet (UV) radiation, the amount that is emitted would be enough to cause severe damage to most forms of life on Earth were it all to reach the surface of the Earth. Fortunately, all of the Sun’s ultraviolet radiation does not reach the Earth because of a layer of oxygen, called the ozone layer encircling the Earth in the stratosphere at an altitude of about 15 miles above the Earth. The ozone layer absorbs much of the Sun’s ultraviolet radiation and prevents it from reaching the Earth. Ozone is a form of oxygen in which each molecule consists of three atoms (O3) instead of the two atoms (O2) usually found in an oxygen molecule. Ozone forms in the stratosphere in a process that is initiated by ultraviolet radiation from the Sun. UV radiation from the Sun splits oxygen molecules with two atoms into free oxygen atoms, and each of these unattached oxygen atoms then joins up with an oxygen molecule to form ozone. UV radiation is also capable of splitting up ozone molecules; thus, ozone is constantly forming, splitting, and reforming in the stratosphere. When UV radiation is absorbed during the process of ozone formation and reformation, it is unable to reach Earth and cause damage there. Recently, however, the ozone layer over parts of the Earth has been diminishing. Chief among the culprits in the case of the disappearing ozone, those that are really responsible, are the chlorofluorocarbons (CFCs). CFCs meander up from Earth into the stratosphere, where they break down and release chlorine. The released chlorine reacts with ozone in the stratosphere to form chlorine monoxide (ClO) and oxygen (O2). The chlorine then becomes free to go through the cycle over and over again. One chlorine atom can, in fact, destroy hundreds of thousands of ozone molecules in this repetitious cycle, and the effects of this destructive process are now becoming evident.

Harvard University, today recognized as part of the top echelon of the world's universities, came from very inauspicious and humble beginning. This oldest of American universities was founded in 1636, just sixteen years after the Pilgrims landed at Plymouth. Included in the Puritan emigrants to the Massachusetts colony during this period were more than 100 graduates of England's prestigious Oxford and Cambridge universities, and these universities graduates in the New Word were determined that their sons would have the same educational opportunities that they themselves had had. Because of this support in the colony for an institution of higher learning, the General Court of Massachusetts appropriated 400 pounds for a college in October of 1636 and early the following year decided on a parcel of land for the school; this land was in an area called Newetowne, which was later renamed Cambridge after its English cousin and is the site of the present-day university. When a young minister named John Harvard, who came from the neighboring town of Charlestown, died from tuberculosis in 1638, he willed half of his estate of 1,700 pounds to the fledgling college. In spite of the fact that only half of the bequest was actually paid, the General Court named the college after the minister in appreciation for what he had done. The amount of the bequest may not have been large, particularly by today's standard, but it was more than the General Court had found it necessary to appropriate in order to open the college. Henry Dunster was appointed the first president of Harvard in 1640, and it should be noted that in addition to serving as president, he was also the entire faculty, with an entering freshmen class of four students. Although the staff did expand somewhat, for the first century of its existence the entire teaching staff consisted of the president and three or four tutors.

Read the following passage and choose the best answer (A, B, C, D):
Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like. What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important. The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem. Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two. Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.

Space Debris
Once something is considered rubbish, we want to throw it away and forget about it. Yet if we are not careful about where we store it, our garbage could come back to haunt us. On the Earth, poorly discarded garbage can cause land, water, and air pollution. And now, people are starting to learn that space debris can also cause a host of different problems. Space debris is defined as a collection of objects that orbit the Earth. Space debris can be classified into two categories. One is man-made rubbish, such as old satellites, rockets, and other machinery left in space after past missions. The other is natural objects, such as meteors that are traveling through space. If you think the man-made garbage doesn’t amount to much, guess again. Researchers estimate that there are over 20,000 pieces of large debris floating around in space and approximately 300,000 smaller pieces in orbit as well. Traveling at speeds of up to 17,500 miles per hour, these objects create a great degree of danger for any spaceships when they leave or return to the Earth. We are lucky to some degree that there haven’t been too many accidents caused by space debris as of yet. Still some incidents have occurred. In 1996, a French satellite was damaged after it crashed into debris from an old French rocket. Then in 2009, an old Russian satellite collided with a working US satellite. The end result was an additional 2,000 pieces of space junk that was added to the junk pile. As the current situation can only worsen, it is now up to the international community to cooperate and create a plan to deal with space debris. For starters, several nations have pledged to take more care with the items they discard in space to cut down on future debris. Researchers are working on devising a way to label space junk, so it can be avoided. Others have proposed more creative techniques to recapture the garbage and discard it on the Earth, or destroy it with lasers. The nightmare scenario that everyone fears is if the Kessler Syndrome starts to occur. This is when the density of garbage becomes so high that it sets off a chain reaction of collisions which would raise the probability of accidents even further. Although there is not a long-term solution in place for space debris, nations are starting to understand the seriousness of this problem.

Recent technological advances in manned and unmanned vehicles, along with breakthroughs in satellite technology and computer equipment, have overcome some of the limitations of divers and diving equipment for scientists doing research on the great oceans of the world. Without a vehicle, divers often became sluggish, and their mental concentration was severely limited. Because undersea pressure affects their speech organs, communication among divers has always been difficult or impossible. But today, most oceanographers avoid the use of vulnerable human divers, preferring to reduce the risk to human life and make direct observations by means of instruments that are lowered into the ocean, from samples take from the water, or from photographs made by orbiting satellites. Direct observations of the ocean floor can be made not only by divers but also by deep-diving submarines in the water and even by the technology of sophisticated aerial photography from vantage points above the surface of more than seven miles and cruise at depths of fifteen thousand feet. In addition, radio-equipped buoys can be operated by remote control in order to transmit information back to land-based laboratories via satellite. Particularly important for ocean study are data about water temperature, currents, and weather. Satellite photographs can show the distribution of sea ice, oil slicks, and cloud formations over the ocean. Maps created from satellite pictures can represent the temperature and the color of the ocean's surface, enabling researchers to study the ocean currents from laboratories on dry land. Furthermore, computers help oceanographers to collect, organize, and analyze data from submarines and satellites. By creating a model of the ocean's movement and characteristics, scientists can predict the patterns and possible effects of the ocean on the environment.
Recently, many oceanographers have been relying more on satellites and computers than on research ships or even submarine vehicles because they can supply a greater range of information more quickly and more effectively. Some of humankind's most serious problems, especially those concerning energy and food, may be solved with the help of observations made possible by this new technology.

Hunting Down the Truth about Killer Whales
Hearing that killer whales are in the area is sure to strike fear in the heart of anyone at sea. The thought of coming across a creature with a menacing name like that is a surefire sign you are on a path to destruction. As it turns out, killer whales, orcas, are actually highly sophisticated creatures that are usually harmless to humans. The title “killer whale” may actually be a mistranslation of the Spanish term “ballena asesina”, which means assassin whale. Orcas were nicknamed this due to their well-coordinated attacks on marine life, not for the danger they pose to humans. At nearly five to seven metres in length and a weight of over six tons, orcas are one of the largest creatures on the Earth. There are about 50,000 orcas worldwide that are spread out in several oceans. Orcas are classified as an Apex predator, which means no other creature hunt them for food. Scientists believe that there are between three to five different types of orca and they are all quite distinctive. The most frequently seen of these are Residents. They live in close-knit family units called pods, which can contain over 50 members, and their diet consists mainly of fish. Transient whales, however, prefer to travel in smaller groups of two to six whales. Meanwhile, Offshore whales were only recently discovered in 1988. They prefer to swim farther away from land than the others and several pods may come together to form groups as large as 200 whales. Although these orca groups may seem similar to the naked eye, they are extremely different in many ways, and scientists believe they haven’t interbred in thousands of years. Researchers also acknowledge that their knowledge of orcas is limited, and even more groups may exist. Male orcas have an average lifespan of about 30 years, while the average age for females is 50. However, there have been cases of females living up to 90 years. Yet when kept in captivity at marine entertainment parks, their life expectancies drop dramatically. In fact, it seems that the biggest threat to orcas these days is humans. Between the practices of hunting orcas, polluting their environments, and capturing them for entertainment purposes, we are making it very difficult for them to survive. Perhaps the killer whales aren’t the real killer after all.

Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very differcent types of flatfish and they have evolved in very separate ways. The skates ad rays, relatives of the rharks, have become flat in what might be called the obivious way. Their bodies have grown out sideways to form grat “wings”. They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such sas plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole, vertically flattened bodies as swimming surfaces, which undulat through the water as they move. Therefore, when their ancestors migrate to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless – In evolution this problem was soleved by the lower eye “moving” around the other side. We see this process off moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion,, so that one eye, for instance the left, moves over the top of the head upwards, an old Picasso – like vision. Incidentally, some species of 20 flatfish settle on the right side, others on left, and others on either side.

According to the passage, the ability of a bony flatfish to move its eyes around is
