XDF 绿皮练习的一道题目

The wild mouflon sheep of the island of Corsica are direct descendants of sheep that escaped from domestication on the island 8000 years ago. They therefore provide arahaeolgists 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 8000 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 8000 years ago.

D) Mouflon sheep are more similar to their for-bears of 8000 years ago than modern domesticated sheep are to theirs.

E) The climate of Corsica has not changed at all in the last 8000 years.

问题：题干能帮我中文解释一下吗？我没明白最后一句话

答案是D， 为什么不是C？

大概是在说:M羊是8000年前家羊的后代,它们是直接从8000年前家羊脱离出来独立发展的,不象那些家羊,它们没有因为后来杂交而变化.所以它们更象8000年前家羊.

C是无关的.

D是support.

support D

C) Modern domesticated sheep are direct descendants of sheep that were wild 8000 years ago.

C is wrong because it is directly against the meaning of the context, which says that the modern domesticated sheep are the results of selective breeding.
