  Insects' lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look "inedible" by imitating plants is a way frequently used by insects to survive. Mammals rarely imitate plants, but many fish and invertebrates do.

   The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.

   Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection; they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.

              Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the plants that they resemble.

  Coincident with concerns about the accelerating loss of species and habitats has been a growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life.

   An alien exploring Earth would probably give priority to the planet's dominants - most distinctive feature - the ocean. Humans have a bias toward land that sometimes get in the way of truly examining global issues. Seen from far away, it is easy to realize landmasses occupy only one-third of the Earth’s surface. Given that two thirds of the Earth's surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species.

   The fact that half of the known species are thought to inhabit the world's rain forests doesn't seem surprising, considering the huge numbers of insects that comprise the bulk of the species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably by sea. Nearly every major type of plant and animal has some presentation there.

   To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water life, on the order of 100 to 100,000 bacteria cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.

  Why does the author compare rain forests and coral reefs in paragraph 1? Most of their inhabitants require water.

• 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 30 to 37.

          The Arts and Crafts Movement in the United States was responsible for sweeping changes in attitudes toward the decorative arts, then considered the minor or household arts. Its focus on decorative arts helped to induce United States museums and private collectors to begin collecting furniture, glass, ceramics, metalwork, and textiles in the late nineteenth and early twentieth centuries. The fact that artisans, who were looked on as mechanics or skilled workers in the eighteenth century, are frequently considered artists today is directly attributable to the Arts and Crafts Movement of the nineteenth century. The importance now placed on attractive and harmonious home decoration can also be traced to this period, when Victorian interior arrangements were revised to admit greater light and more freely flowing spaces.

          The Arts and Crafts Movement reacts against mechanized processes that threatened handcrafts and resulted in cheapened, monotonous merchandise. Founded in the late nineteenth century by British social critics John Ruskin and William Morris, the movement revered craft as a form of art. In a rapidly industrializing society, most Victorians agreed that art was an essential moral ingredient in the home environment, and in many middle- and working-class homes craft was the only form of art. Ruskin and his followers criticized not only the degradation of artisans reduced to machine operators, but also the impending loss of daily contact with handcrafted objects, fashioned with pride, integrity, and attention to beauty.

          In the United States as well as in Great Britain, reformers extolled the virtues of handcrafted objects: simple, straightforward design; solid materials of good quality; and sound, enduring construction techniques. These criteria were interpreted in a variety of styles, ranging from rational and geometric to romantic or naturalistic. Whether abstract, stylized, or realistically treated, the consistent theme in virtually all Arts and Crafts design is nature.

            The Arts and Crafts Movement was much more than a particular style; it was a philosophy of domestic life. Proponents believed that if simple design, high-quality materials, and honest construction were realized in the home and its appointments, then the occupants would enjoy moral and therapeutic effects. For both artisan and consumer, the Arts and Crafts doctrine was seen as a magical force against the undesirable effects of industrialization.

  The word “extolled” in the third paragraph is closest in meaning to ________.
