Bottom trawling is a type of deep-sea fishing that involves dragging a large net along the bottom of the ocean, and it results in catching and killing many unintended species, some of which are endangered. Environmental advocates, concerned for these endangered marine species, have recommended that commercial fishers use a new set of nets, each designed specifically for the size and shape and pheromones (chemical attractors) of an individual marine species targeted by the commercial fishers. Environmentalists hope use of these new nets will protect the endangered marine species without interrupting commercial deep-sea fishing.

Which of the following, if true, most strongly supports the claim that the use of the new nets will have the intended effects?
  • AThe pheromones that would most attract the species sought by commercial fishers indicate the presence of a dangerous threat to most of the endangered marine species 分析该选项
  • BSome endangered marine species are particularly large, as large any species targeted by commercial deep-sea fishing. 分析该选项
  • CMost of the newly design nets are not significantly more expensive than a typical bottom trawling system. 分析该选项
  • DCatching unintended, endangered species adds nothing to the profits of a commercial deep-sea fishing company. 分析该选项
  • EFreshwater fishers often increase the odds of catching a desired fish, and avoid catching unintended species, by the specific design of the fishing hook. 分析该选项
正确答案: A
