GWD21-Q10

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

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



A.Whether artifacts from Ashkelon were widely traded to non-Canaanite cities?

B.Whether significant numbers of artifacts that do not resemble artifacts produced in Ashkelon have been found at Avans?


C.Whether Avans 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 Avans?

E.Whether any artifacts produced by the Hyksos after 1550 B.C .have been found in Egypt


为什么是A  ？  看了前人的帖子说 如果 artifacts from Ashkelon were widely traded to non-Canaanite  ，那么就不是invade的时候带过去的，就不能判断起源。  我不理解啊，为什么 trade 过去就不能判断起源了呢，trade 过去的也是起源于 Canaanite 的啊
