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.

Which aspect of butterflies does the passage mainly discuss?

A. Their adaptation to different habitats

B. Their names 

C.Their physical characteristics

D. Their variety

These days in business, people have to face many challenging questions when designing and implementing new projects in undeveloped areas of the countryside.

It is unfortunate that in the past this has often been true, and it has been necessary to choose between (26) ________ the project or protecting the environment. However, by taking environmental considerations (27) ______ at an early stage in a project, companies can significantly reduce any impact on local plants and animals. For example, in southern Africa, a company called CEL was asked to put up 410 km of a power transmission line without disturbing the rare birds which inhabit that area. The project was carried out with (28) _____ disturbance last summer. What may surprise many business people is the fact that this consideration for local wildlife did not in any way slow down the project. Indeed, the necessary advance planning combined with local knowledge and advanced technology, (29) ______ that the project was actually completed ahead of schedule. CEL was contracted to finish the job by October and managed to do so two months earlier.
