题目：
Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.
Which of the following, if true, most strengthens the argument?
Which of the following, if true, most strengthens the argument?
选项:
A、The population of sea urchins, the main food of sea otters, has increased since the sea otter population declined.
B、Seals do not eat sea otters, nor do they compete with sea otters for food.
C、Most of the surviving sea otters live in a bay that is inaccessible to orcas.
D、The population of orcas in the Aleutian Islands has declined since the 1980s.
E、An increase in commercial fishing near the Aleutian Islands in the 1980s caused a slight decline in the population of the fish that seals use for food.
答案:
C
提问：
题干要支持的信息：otter数量锐减，就是被orcas吃掉了。原文后面一些背景细节信息反复说证明otters就是被orcas吃掉的。A提到另一种生物是被otter吃的，完全内在逻辑链上 杀。B orcas也吃的seals不跟otters争食也不以otter为食，证明不了就是orcas吃掉的otter。杀。C 先放着 D orcas数量变化，跟是否orcas吃的otter无关。杀。E 捕鱼的多了 我这个瞎扯 杀。所以C根本没有在拎出逻辑链的那一刻对应上，至少杀出来了正确选项 请老师看我这么杀选项的逻辑可取吗 请纠正
