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 38 to 47.
 Plants and animals will find it difficult to escape from or adjust to the effects of global warming. Scientists have already observed shifts in the lifecycles of many plants and animats, such as flowers blooming earlier and birds hatching earlier in the spring. Many species have begun shifting where they live or their annual migration patterns due to warmer temperatures.
 With further warming, animals will tend to migrate towards the poles and up mountainsides towards higher elevations. Plants will also attempt to shift their ranges, seeking new areas as old habitats grew too warm. In many places, however, human development will prevent these shifts. Species that find cities or farmland blocking their way north or south may become extinct. Species living in unique ecosystems, such as those found in polar and mountaintop regions, are especially at risk because migration to new habitats is not possible. For example, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther north to go.
 Projecting species extinction due to global warming is extremely difficult. Some scientists have estimated that 20 to 50 percent of species could be committed to extinction with 2 to 3 Celsius degrees of further wanning. The rate of warming, not just the magnitude, is extremely important for plants and animals. Some species and even entire ecosystems, such as certain types of forest, may not be able to adjust quickly enough and may disappear.
 Ocean ecosystems, especially fragile ones like coral reek, will also be affected by global warming, warmer ocean temperatures can cause coral to "bleach", a state which if prolonged will lead to the death of the coral. Scienists estimate that even I Celsius degree of additional warming could lead to widespead bleaching and death of coral reefs around the world. Also, increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters. This acidification further stresses ocean ecosystems.

 Overpopulation, the situation of having large numbers of people with too few resources and too little space, is closely associated with poverty. It can result from high population density, or from low amounts of resources, or from both. Excessively high population densities put stress on available resources. Only a certain number of people can be supported on a given area of land, and that number depends on how much food and other resources the land can provide. In countries where people live primarily by means of simple fanning, gardening, herding, hunting, and gathering, even large areas of land can support only small numbers of people because these labour intensive subsistence activities produce only small amounts of food.
 In developed countries such aa lite th United States, Japan, and the countries of Western Europe, overpopulation generally is not considered a major cause of poverty. These countries produce large quantitics of food through mechanized farming, which depends on commercial fertilizers, large-scale irrigation, and agricultural machinery. This form of production provides enough food to support the high densities of people in metropolitan areas.
 A country’s level of poverty can depend greatly on its mix of population density and agricultural productivity. Bangladesh, for example, has one of the world’s highest population densities, with 1,147 persons per sq km. A large majority of the people of Bangladesh engage in low - productivity manual farming, which contributes to the country's extremely high level of poverty. Some of the smaller countries in Western Europe, such as the Netherlands and Belgium, have high population densities as well. These countries practise mechanized farming and are involved in high-tech industries, however, and therefore have high standards of living.
 At the other end of the spectrum, many countries in sub-Saharan Africa have population densities of less than 30 persons per sq km. Many people in these countries practise manual subsistence farming; these countries also have infertile land, and lack the economic resources and technology to boost productivity. As a consequence, these nations are very poor. The United Slates has both relatively low population density and high agricultural productivity; it is one of the world's wealthiest nations.
 High birth rates contribute to overpopulation in many developing countries. Children are assets to many poor families because the provide labour, usually for farming. Cultural norms in traditionally rural societies commonly sanction the value of large families. Also, the governments of developing countries often provide little or no support, financial or political, for family planning; even people who wish to keep their families small have difficulty doing so. For all these reasons, developing countries lend to have high rates of population growth.
Question 55: Which of the following is given a definition in paragraph I?
A. Overpopulation	B. Population density	C. Simple farming D. Poverty
Question 56: What will suffer when there are excessively high population densities?
A. Available resources	B. Skilled labor 	C. Farming methods D. Land area
Question 57: The phrase "that number" in paragraph 1 refers to the number of ____
A. people 	B. densities 	C. resources D. counlries
Question 58: In certain countries, large areas of land can only yield small amounts of food because
A. there is a lack of mechanization 	B. there are small numbers of labourers
C there is on abundance of resources 	D. there is no shortage of skilled labour
Question 59: Bangladesh is a country where the level of poverty depends greatly on_____
A. its population density only 
B. both population density and agricultural productivity
C population density in metropolitan areas
D. its high agricultural productivity
Question 60: The phrase “engage in” in paragraph 3 is closest in meaning to _______. 
A. escape from 	B. look into 	C. give up 	D. participate in
Question 61: The word “infertile” in paragraph 4 probably means ______. 
A. disused 	B. impossible 	C. unproductive 	D. inaccessible
Question 62: Which of the following is TRUE, according to the passage? 
A. In certain developed countries, mechanized farming is applied. 
B. In sub-Saharan African countries, productivity is boosted by technology.
C. There is no connection between a country’s culture and overpopulation. 
D. All small countries in Western Europe have high population densities.
Question 63: Which of the following is a contributor to overpopulation in many developing countries? 
A. High-tech facilities 	B. Economic resources 
C. Sufficient financial support 	D. High birth rate
Question 64: Which of the following could be the best title for the passage? 
A. High Birth Rate and its Consequences 	B. Overpopulation: A Cause of Poverty
