Read the following passage and mark A, B, C or D on your answer sheet to indicate the correct answer for each of the questions
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.
What is the main point of the passage?
A.The sea is even richer in life than the rain forest
B.Humans are destroying thousands of species.
C.Coral reefs are similar to rain forests.
D.There are thousands of insect species.

University researchers have taken samples from a preserved dodo specimen in an (31) _____ to uncover the extinct bird’s family tree. They worked with the British Natural History Museum to collect and study genetic material from large number of specimens: a preserved dodo, the extinct solitaire bird, and 35 kind of living pigeons and doves. Their analysis (32) _____ the doo and the solitaire to be close relatives with the Nicobar pigeon, their nearest living relative. The dodo lived on Mauritius in the Indian Ocean. It was a flightless bird, bigger than a turkey. By 1681, all dodos had been (33) _____ by hungry sailors. The solitaire, which looked a bit like a dodo, had gone the same way by 1800. By extracting short pieces of the dodo’s DNA and (34) _____ these with the DNA of living birds, the scientists were able to deduce when the dodo evolved away from its relatives into a separate entity. The scientists can now (35) _____ assume that the dodo developed its distinctive appearance and features as a result of its geographical isolation. They are now convinced that it separated from the solitaire about 25 million years ago, long before Mauritius became an island.
