Read the following passage and mark the letter A,B, C or Don your answer sheet to indicate the correct answer to each of the questions.

Butterflies are among the most extensively studied insectsan 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.

The word “striking” in paragraph 2 is closest in meaning to_____________

The Art World

One of the maj or problems in the art world is how to distinguish and promote an artist. In effect, a market must be created for an artist to be successful.The practice of signing and numbering individual prints was introduced by James Abbott McNeill whistler, the nineteenth - century artist best known for the painting of his mother, called “Arrangement in Grey and Black”, but known to most of us as“ whistler’s Mother”. Whistler’s brother - in - law, Sir Francis Seymour Haden, a less well - known artist, had speculated that collectors might find prints more attractive if they knew that they were only a limited number of copies produced. By signing the work in pencil, an artist could guarantee and personalize each print. As soon as Whistler and Haden began the practice of signing and numbering their prints, their work began to increase in value, when other artists noticed that the signed prints commanded higher prices, they began copying the procedure. Although most prints are signed on the right - hand side in the margin below the image, the placement of the signature is a matter of personal choice. Indeed, prints have been signed within the image, in any of the margins, or even on the reverseside of the print, wherever the artist elects to sign it, a signed print is still valued above an unsigned one, even in the same edition.

So widespread has texting become, however, that even pigeons have started doing it. (34) _____________, in this case, it’s difficult to view the results as anything but positive. Twenty of the birds are about to take to the skies with the task of measuring air pollution, each (35) _____________with sensor equipment and a mobile phone. The readings made by the sensors will be automatically converted into text messages and beamed to the Internet - (36) _____________they will appear on a dedicated ‘pigeon blog’. The birds will also each have a GPS receiver and a camera to capture aerial photos, and researchers are building a tiny ‘pigeon kit’ containing all these gadgets. Each bird will carry these in a miniature backpack, (37) ____________ , that is, from the camera, which will hang around its neck. The data the pigeons text will be displayed in the form of an interactive map, which will provide local residents with up-to-the-minute information on their local air quality.
