The following paragraphs are given in a wrong order. For Questions 41-45, you are required to reorganize these paragraphs into a coherent article by choosing from the list A-G. Some of the paragraphs have been placed for you. (10 points)
A. Concerned citizens and scientists have begun to take action. A wide range of solutions is being proposed to stop the destruction of biodiversity at the regional as well as the global level. Since 1985, the effort has become more precisely charted, economically efficient, and politically sensitive.
B. The new biodiversity studies will lead logically to an electronic encyclopedia of life designed to organize and make immediately available everything known about each of the millions of species. The industrialized countries will lead for a time. However, the bulk of the work must eventually be done in the developing countries. The latter contains most of the world species, and they are destined to benefit soonest from the research. The technology needed is relatively inexpensive, and its transfer can be accomplished quickly. The discoveries generated can be applied directly to meet the concerns of greatest importance to the geographic region in which the research is conducted, being equally relevant to agriculture, medicine, and economic growth.
C. In the midst of this richness of life forms, however, the rate of species extinction is rising, chiefly through habitat destruction. Most serious of all is the conversion of tropical rainforests, where most species of animals and plants live. The rate has been estimated, by two independent methods, to fall between 100 and 10,000 times the pre-human background rate, with 1,000 times being the most widely accepted figure. The price ultimately to be paid for this cataclysm is beyond measure in foregone scientific knowledge; new pharmaceutical and other products; ecosystems services such as water purification and soil renewal; and, not least, aesthetic and spiritual benefits.
D. Since the current hierarchical, binomial classification was introduced by Carolus Linnaeus 250 years ago, 10 percent, at a guess, of the species of organisms have been described. It is believed that most and perhaps nearly all of the remaining 90 percent can be discovered, diagnosed, and named in as little as about 25 years. That potential is the result of two developments needed to accelerate biodiversity studies.
E. The increasing attention given to the biodiversity crisis highlights the inadequacy of biodiversity research itself. Earth remains in this respect a relatively unexplored planet. The total number of described and formally named species of organisms has grown, but not by much, and today is generally believed to lie somewhere between 1.5 million and 1.8 million The full number, including species yet to be discovered, has been estimated in various accounts that differ according to assumptions and methods from an improbably low 3.5 million to an improbably high 100 million. By far the greatest fraction of the unknown species will be insects and microorganisms.
F. The past decade has witnessed the emergence of a much clearer picture of the magnitude of the biodiversity problem. Put simply, the biosphere has proved to be more diverse than was earlier supposed, especially in the case of small microorganisms. An entire domain of life, the Archaea, has been distinguished from the bacteria, and a huge, still mostly unknown and energetically independent environment has been found to extend three kilometers or more below the surface of Earth.
G. The first is information technology, with which high-resolution digitized images of specimens can now be obtained. Moreover, type specimens, scattered in museums around the world can now be photographed and made instantly available everywhere as "types" on the Internet. The second revolution about to catapult biodiversity studies forward is genomics, which will soon enable scientists to describe bacterial and Achaean species by partial DNA sequences and to subsequently identify them by genetic bar-coding.
Order: F is the first paragraph and B is the last.
