SEATTLE (May 1 ) – Researchers at technology firm Nylobe, Inc., are working to develop a sensor capable of detecting corrosion caused by environmental exposure. Corrosion is a major contributor to ---143--- losses in the aircraft industry each year. "This will be a major ---144--- for commercial airline fleets," says Mel Laveau, Nylobe's CEO. "The sensor will decrease both labor and maintenance costs   without being too expensive."
According to Ms. Laveau, the sensor will work by detecting corrosion in its early stages, when the problem can be corrected simply by removing the corroded material. ---145---. In the structure of large aircraft, some critical joints can be particularly susceptible to corrosion. ---146---, the sensor can be used to inspect these areas and then target the most likely areas of concern.

The Wonders of Wetlands
If you’re searching for scenic places or areas, visiting wetlands probably won’t be high on your list. Wetlands are areas of land that are often saturated with water and they are quite an eyesore. Although they might not look very pretty, they play an important part in keeping the environment clean and suitable for plant and animal life. With the exception of Antarctica, wetlands occur naturally on every continent. There are many different types of wetlands on the Earth, including bogs, swamps, and marshes. Along with rainforests, they are among the most diverse places on the Earth. In addition to naturally-occurring wetlands, humans are creating artificial ones for a number of purposes related to water management. One of the main benefits of wetlands is that they can prevent floods. They do so by storing water temporarily and then slowly releasing it over time. Wetlands operate similarly to a sponge. When it rains heavily and water levels rise, they absorb the excess water. This prevents runoff from entering streams and keeping them from overflowing. Then, when water levels become low in the future, they will release it. In many cases, wetlands offer a much more affordable solutions than dams. However, it’s important to note that wetlands, like dams, don’t eliminate all dangers from flooding. In cases of extremely heavy rainfall, wetlands can fill up and any additional water will start to run off. Wetlands can also play a part in water purification. Agricultural practices, urban runoff, and sewage waste are a major cause of water pollution. Wetlands contain plants and organisms that can reduce this pollution by filtering out unwanted substances such as chemicals, and decomposing matter, as well as sediment. Wetlands have additional benefits for the environment as well. They can help to feed nearby fish populations by releasing vegetative matter to rivers. Also, many amphibians use wetlands as breeding grounds because it provides places for foraging and the shallow water they require for reproduction. Some birds also use wetlands for migration, as they can settle in trees and then raid the wetland’s waters for fish when they’re hungry. Although wetlands may not look pretty, it’s clear that they are capable of doing the dirty work required to keep our planet clean and ensure that the circle of life remains unbroken.

Saving the Rainforests
One of the hottest topics related to the environment is rainforests. Despite always being mentioned in the news, many people don’t know very much about these areas or understand why they are so important. The name “rainforest” actually does a pretty good job of describing what they are – tall forests that receive high amounts of precipitation. In a year, rainforests get between 250 to 450 centimetres of precipitation. There are two types of rainforests: tropical rainforests and temperate rainforests. Tropical rainforests are more plentiful and are located in warmer climates, while temperate rainforests are found in places where the weather is a bit milder. In terms of location, rainforests can be found on every continent with the exception of Antarctica. Although they only cover 6 percent of the Earth, over 50 percent of the Earth’s animal and plant species can be found there. Many biologists estimate that there are possibly millions of additional species present there that have yet to be discovered and classified. Over the years, rainforests have gained the nickname “the world’s pharmacy” because more than 25 percent of natural medicines were found there. Many herbs that are used to make medicines can only be found in rainforests. Rainforests are also home to several tribes that have lived off the land for thousands of years. During this time, they have survived by hunting animals and gathering fruits and vegetables. They also possess tremendous knowledge when it comes to crafting and applying medicines made from herbs and plants. Over time, their unique way of life has declined as they have come in contact with modern civilization. Despite their numerous benefits, rainforests have been disappearing at a rapid speed. As the Earth’s population continues to expand, developers have been cutting down their trees to create new lands for farming or urban projects. This could have unfortunate long-term effects on our planet. If deforestation continues at this rate, it is possible that a quarter of all species on the Earth may become extinct in the next 50 years. As it stands, plenty of damage has already occurred. West Africa has had 90 percent of its rainforests destroyed, while the island nation of Madagascar has eliminated 66 percent of its original rainforests as well. As a result, many charities have sprung up with the goal of purchasing and protecting the remaining rainforests. With their help, hopefully we can stop the destruction of one of the planet’s most vital assets.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Rachek Carson was born in 1907 in Springsdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master’s degree in 1933. In 1936, she was hired by the US Fish and Wildlife Service, where she worked most of her life.
Carson’s first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around US, which provided a fascinating look beneath the ocean’s surface, emphasizing human history as well as geology and marine biology. Her imagery and language had a poetic quality. Carson consulted no less than 1, 000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers.
In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokesmen for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work vindicated a 1963 report of the President’s Science Advisory Committee.
