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 from 35 to 42.
Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.

Read the following passage and mark the letter A, B, C, or D on your sheet to indicate the correct answer to each of the questions from 40 to 47.
Microplastics are small plastic pieces less than five millimeters in size. Some microplastics are manufactured, such as the microbeads added to health and beauty products, while others result from larger plastics gradually breaking down. These plastics are pervasive in marine environmets, and they are known to harbour toxic substances such as heavy metals and phthalates.
Since many animals are known to eat microplastics, scientists are concerned about the toxic substances contained within them, as well as their capacity to accumulate within the animals and stop them from absorbing nutients correctly.
Even the largest marine creatures are vulnerable to tiny fragments of plastic littering the world’s oceans. A new study has found whales and whale sharks – the largest fish in the world – are ingesting microplastics in alarming quantities. These creatures are filter feeders, meaning they consume large quantities of small prey by straining them out of the ocean water. In the process, they swallow hundreds to thousands of cubic meters of water daily, meaning there ti the potential for them to take in substanial amounts of microplastic floating in the water.
Recently, plastic pollution has received a lot of attention for its effects on marine animals. In the UK, mircobeads have been banned, and other plastic items such as water bottles and disposable coffee cups have also been in the firing line. However, while scientists argee that plastic pollution is a problem for marine animals, there is still a lot they do not know about magnitude of its impact.
Which of the following terms is defined in the passage?
A.phthalates
B.heavy metals 
C.mircobeads
D.mircoplastics
