9.The Nile Delta of Egypt was invaded and from 1650 to 1550 B.C. by a people called the Hyksos. Their origin is uncertain, but archaeologists hypothesize that they were Canaanites. In support of this hypothesis, the archaeologists point out that excavations of Avaris, the Hyksos capital in Egypt, have uncovered large numbers of artifacts virtually identical to artifacts produced in Ashkelon, a major city of Canaan at the time of the Hyksos invasion.

In order to evaluate the force of the archaeologists’ evidence, it would be most useful to determine which of the following?

A.Whether there were some artifacts found at Avaris that were unlike those produced in Ashkelon but that date to before 1700 B.C.  

B.Whether the Hyksos ruled any other part of Egypt besides the Delta in the period from 1650 to 1550 B.C.

C.Whether Avaris was the nearest Hyksos city in Egypt to Canaan  

D.Whether Ashkelon after 1550 B.C. continued to produce artifacts similar to those found at Avaris  

E.Whether many of the artifacts found at Avaris that are similar to artifacts produced in Ashkelon date to well before the Hyksos invasion  

答案;E

我不太明白A选项，有没有大牛可以给我解释一下，谢谢啦！！！

果因推理找削弱/支持

前提（果）： excavations of Avaris, the Hyksos capital in Egypt, have uncovered large numbers of artifacts virtually identical to artifacts produced in Ashkelon, a major city of Canaan at the time of the Hyksos invasion
结论（因）：the Hyksos were Canaanites

前提和结论之间有一个gap:  虽然Avaris发现的artifacts跟Ashkelon的一样，但并没有说哪个在前哪个在后。也就是究竟是Avaris发现的artifacts是从Ashkelon来的（这样就支持结论）？还是Ashkelon的artifacts是从Avaris来的（这样就削弱结论）？
E正好填补了这个gap: Whether many of the artifacts found at Avaris that are similar to artifacts produced in Ashkelon date to well before the Hyksos invasion. 许多Avaris发现的artifacts都是the Hyksos invasion之前的。

A选项that were unlike those produced in Ashkelon but that date to before 1700 B.C修饰some artifacts found at Avaris

太感谢了，终于弄明白了，一开始没理解A选项两个that都是修饰some artifacts found at Avaris。
