T-9-Q8.

A sudden increase in the production of elephant ivory artifacts on the Mediterranean coast of North Africa occurred in the tenth century. Historians explain this increase as the result of an area opening up as a new source of ivory and argue on this basis that the important medieval trade between North Africa and East Africa began at this period.

Each of the following, if true, provides some support for the historians’ account described above EXCEPT?

A.      In East Africa gold coins from Mediterranean North Africa have been found at a tenth-century but at no earlier sites.

B.      The many surviving letters of pre-tenth-century North African merchants include no mention of business transactions involving East Africa.

C.      Excavations in East Africa reveal a tenth-century change in architectural style to reflect North African patterns.

D.      Documents from Mediterranean Europe and North Africa that date back earlier than the tenth century show knowledge of East African animals.

E.       East African carvings in a style characteristic of the tenth century depict seagoing vessels very different from those used by local sailors but of a type common in the Mediterranean.


B、D 很难排除。答案是D  我选的是B    B .pre-tenth-century   D .earlier than the tenth century   请教各位,  可以为我解答吗?

B的意思是：10世纪以前的许多书信没有显示北非和东非有贸易出现。这没有否定“10世纪以后，可能会有贸易出现”，也就是间接支持了“北非和东非贸易开始于10世纪之后”的结论。因此，不是正确答案。

D的意思是：早在10世纪以前，北非和地中海地区就出现了关于东非动物的纪录。这多少可以说明10世纪以前，北非和东非就有了联系，而这种联系可能就是贸易。所以间接否定了“北非和东非的联系开始于10世纪”的结论。所以是正确答案。
