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.
这道题大家如何考虑呢？我用XDF的一些针对假设题的技巧，感觉行不通，希望大家给自由一些清新的思路，开阔一下思维方式的空间。谢谢大家。

D, 取反。
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
