Two years later, the McKay team announced that ALH84001, which scientists generally agree originated
11、on Mars, contained compelling evidence that life once existed on Mars. This evidence includes the discovery of organic molecules in ALH84001, the first ever found in Martian rock. Organic moleculescomplex, carbonbased compoundsform the basis for terrestrial life. The organic molecules found in ALH84
12、001 are polycyclic aromatic hydrocarbons, or PAHs. When microbes die, their organic material often decays into PAHs. Skepticism about the McKay teams claim remains, however. For example, ALH84001 has been on earth for 13,000 years, suggesting to some scientists that its PAHs might have resulted form
13、 terrestrial contamination. However, McKays team has demonstrated that the concentration of PAHs increases as one looks deeper into ALH84001, contrary to what one would expect from terrestrial contamination. The skeptics strongest argument, however, is that processes unrelated to organic life can ea
14、sily produce all the evidence found by McKay s team, including PAHs. For example, star formation produces PAHs. Moreover, PAHs frequently appear in other meteorites, and no one attributes their presence to life processes. Yet McKays team notes that the particular combination of PAHs in ALH84001 is m
15、ore similar to the combinations produced by decaying organisms than to those originating form nonbiological processes.-Q5: The passage asserts which of the following about the claim that ALH84001 originated on Mars?A. It was initially proposed by the McKay team of scientists.B. It is not a matter of
16、 widespread scientific dispute.C. It has been questioned by some skeptics of the McKay teams work.D. It has been undermined by recent work on PAHs.E. It is incompatible with the face that ALH84001 has been on Earth for 13,000 years.-Q6: The primary purpose of the passage is toA. describe new ways of

ALH84001 may not have originated on
19、 Mars.B. ALH84001 contains PAHs that are the result of nonbiological processes.C. ALH84001 may not have contained PAHs when it landed on Earth.D. The organic molecules found in ALH84001 are not PAHs.E. The organic molecules found in ALH84001 could not be the result of terrestrial contamination.GWD3-

31、o Q15:In its 1903 decision in the case of Lone Wolf v. Hitchcock, the United States Supreme Court rejected the efforts of three Native American tribes to prevent the opening of tribal lands to non-Indian settlement without tribal consent. In his study of the Lone Wolf case, Blue Clark properly empha
32、sizes the Courts assertion of a virtually unlimited unilateral power of Congress (the House of Representatives and the Senate) over Native American affairs. But he fails to note the decisions more far-reaching impact: shortly after Lone Wolf, the federal government totally abandoned negotiation and
33、execution of formal written agreements with Indian tribes as a prerequisite for the implementation of federal Indian policy. Many commentators believe that this change had already occurred in 1871 whenfollowing a dispute between the House and the Senate over which chamber should enjoy primacy in Ind
34、ian affairsCongress abolished the making of treaties with Native American tribes. But in reality the federal government continued to negotiate formal tribal agreements past the turn of the century, treating these documents not as treaties with sovereign nations requiring ratification by the Senate b
35、ut simply as legislation to be passed by both houses of Congress. The Lone Wolf decision ended this era of formal negotiation and finally did away with what had increasingly become the empty formality of obtaining tribal consent.-Q12: The author of the passage is primarily concerned withA. identifyi

Prior to 1871, the federal government sometimes negotiated treaties with Native American tribes.E. Following 1871,
39、 the House exercised more power than did the Senate in the governments dealings with Native American tribes.-Q14: As an element in the argument presented by the author of the passage, the reference to Blue Clarks study of the Lone Wolf case serves primarily toA. point out that this episode in Native
