5. 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? (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 descen- dants of sheep that were wild 8,000 years ago. (D) Mouflon sheep are more similar to their fore- bears of 8,000 years ago than modern domes- ticated sheep are to theirs. (E) The climate of Corsica has not changed at all in the last 8,000 years.
原文中说了therefore provide archaeologists with a picture of what some early domesticated sheep looked like 既然这么说,那当然是首先他自己就要认为 mouflon sheep are more similar to their fore- bears of 8,000 years ago than modern domes- ticated sheep are to theirs 这就是假设嘛 还有,你怎么老是不贴答案啊,老MY已经生气咯,呵呵
