Q19:Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development. They plan to do this by purchasing that land from the farmers who own it. That plan is ill-conceived: if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders. On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable. But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires. And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability. In the argument as a whole, the two boldface proportions play which of the following roles? - The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection.
- The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.
- The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.
- The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.
- The first presents a goal that the argument endorses; the second presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.
Answer: D 这题怎么看是D所说的那样，我选了B，因为我觉得第一句是environmental organization想保护环境可是最终不能达成，而第二句是说到因为farming it remains viable，所以不卖而导成environmental organization不能达成目标. --------------------- Q22: Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter’s atmosphere in 1994, but they did not show how big those fragments were. Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter’s outer atmosphere. After the fragments’ entry, these analyses revealed unprecedented traces of sulfur. The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter’s outer atmosphere does contain sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter’s outer atmosphere without being burned up. In the astronomer’s argument, the two portions in boldface play which of the following roles? - The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim.
- The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim.
- The first and the second are each considerations advanced in support of the conclusion of the argument.
- The first provides evidence in support of the conclusion of the argument; the second is that conclusion.
- The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.
