[求助]XDF小蓝155

155.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 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?

B.There are no other existing breeds of sheep that  escaped from domestication at about the same time as the forebears of the mouflon.

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

答案选D,B怎么就不对呢?希望有高手指教,谢谢。
