问题 The wild mouflon sheep of the island of Corsica are direct descendants of sheep that escaped from domestication on the island 8,000 years ago. They therefore provide archaeologists with a picture of what some early domesticated sheep looked like, before the deliberate selective breeding that produced modern domesticated sheep began. The argument above makes which of the following assumptions?
选项 A、The domesticated sheep of 8,000 years ago were quite dissimilar from the wild sheep of the time.
B、There are no other existing breeds of sheep that escaped from domestication at about the same time as the forebears of the mouflon.
C、Modern domesticated sheep are direct descendants of sheep that were wild 8,000 years ago.
D、Mouflon sheep are more similar to their forebears of 8,000 years ago than modern domesticated sheep are to theirs.
E、The climate of Corsica has not changed at all in the last 8,000 years.
答案 D
解析 本题要关注三个关键词：“the wild mouflon sheep”、“early domesticated sheep”与“modern domes—ticated sheep”。(D)涉及这三个关键词，指出“mouflon sheep”相比较于“modern domesticated sheep”而言，与早期驯养的绵羊更相似，从而做了一个很好的假设，如果“mouflon sheep”还没有“modern domesticated sheep”提供的信息多，那么考古学家完全可以通过家庭驯养羊去研究早期驯羊的模样，则上面结论不成立。所以(D)正确；(C)易误选，但(C)只涉及关键词“modern domesticated sheep”，而没有说明“mouflon sheep”怎么样，所以必然不对。
