各位,请给个说法。。。。
The wild mouflon sheep of the laceType>islandlaceType> of laceName>CorsicalaceName>
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. |
