The waters off the coast of Iceland are filled with pods of killer whales, which migrate there during the summer. Wildlife parks that rely on the killer whales for entertainment hunt the killer whale almost exclusively in the water of Iceland, because strict sanctions forbid them from doing so off the coast of North America, an area also abundant in killer whales. Since Iceland recently gave into pressure from international groups opposed to the hunting of killer whales, it too will forbid the hunting of killer whales off its coast. Therefore, all wildlife parks will be forced to end their shows featuring killer whales once their current killer whales are unable to perform.
All of the following cast doubt on the conclusion of the argument EXCEPT?
A.The recent ban only extends to within one hundred miles of Iceland, though killer whales are plentiful along the shores of Greenland, which fall outside this range.
B.The incoming prime minister of Canada, who is more conservative, is planning on lifting the ban on hunting killer whales off the coast of Canada.
C.In-park killer whale births have become increasingly common, especially in those wildlife parks that harbor a large number of killer whales.
D.Some wildlife parks are involved in the illegal trade of killer whales.
E.It is nearly impossible to catch killer whales in deep waters, so hunters typically rely on luring killer whales into coves.
The argument states that the only place wildlife parks can find killer whales is off the coast of Iceland, yet, with an imminent ban there, wildlife parks will be unable to replenish their respective in-park killer whale populations. Eliminate all the answer choices that call this question into conclusion.
(A) provides a source of killer whales (Greenland), thereby weakening the conclusion.
The argument states that North America is also abundant in killer whale. If Canada lifts its ban, then wildlife park can find killer whale there. (B) is out.
(C) provides a great place to replenish the killer whale population: the park itself. Therefore, (C) directly attacks the argument that wildlife parks will run out of killer whale.
(D) provides a clear means by which parks will acquire killer whales despite all the bans.
(E) does not provide a new means by which parks will acquire new killer whales. It only describes how killer whales are generally caught. Therefore (E) is the answer.作者: liuox 时间: 2013-10-7 14:41:55
