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.

        A mansion is a very large home. McDonald's is the name of a fast food hamburger chain. What do you get when you put the two together? You get McMansion, the recently created name for a type of large suburban, two storied home that originated in the United States. Many people love McMansions for their low price, abundant space and impressive styling, but the news is not all gooD. In fact, McMansions may now be a threatened species.

        McMansion became very popular in the United States during the 1990s, and this popularity continued for almost 20 years. During those years the economy was relatively strong, and banks were willing to lend large sums of money to people who wanted to buy a home. The result was an increase in the average home size. In 1988, the average new American home was 170 square meters, but by 2008 this had risen to 244 square meters, a 44% increase.

        To offset the greater costs of these large homes, land developers built many homes that all used a similar basic design and identical construction methods. Framing and interior fittings were constructed in

factories, instead of on site, and the materials used were often of a lower quality. Finally, the sections of land used for each house were much smaller than before.

        The result was suburban developments full of huge homes, often over 280 square meters in floor area, that all looked similar to each other. Their standardization and lowest possible-cost construction reminded people of McDonald's hamburgers, hence the term McMansion. For many people a McMansion was their dream home, but that dream is now rapidly turning sour.

        There are two main problems with McMansions. One problem is that their huge size means that they cost a lot to heat or cool. Energy is becoming more expensive, so owners are faced with huge bills if they try to heat or cool their home. The other problem is that McMansion owners are often in a lot of debt. They borrowed a lot of money to pay for their impressive home, but during the 2000s, with struggling economy and high unemployment, they couldn't afford to repay their loan.

        McMansion are still popular in some area, but no one is sure how long it will last. Will energy become even more expensive and force owners to downsize? Will the economy grow and banks become more willing to end again? Will the drop-in house prices allow larger, less affluent families to afford a McMansion? These questions are weighing heavily on the future of one of the most popular housing styles of the late 20th century.

Read the followingpassage carefully and then choose the best answer to each question.

Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.

Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.

For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed.

A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.

In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.
