Archaeologists seeking the location of a legendary siege and destruction of a city are excavating in several possible places, including a middle and a lower layer of a large mound. The bottom of the middle layer contains some pieces of pottery of type 3, known to be from a later period than the time of the destruction of the city, but the lower layer does not.

19.   Which of the following hypotheses is best supported by the evidence above?

(A) The lower layer contains the remains of the city where the siege took place.

(B) The legend confuses stories from two different historical periods.

(C) The middle layer does not represent the period of the siege.

(D) The siege lasted for a long time before the city was destroyed.（C）

(E) The pottery of type 3 was imported to the city by traders.

20.   The force of the evidence cited above is most seriously weakened if which of the following is true?

(A) Gerbils, small animals long native to the area, dig large burrows into which objects can fall when the burrows collapse.

(B) Pottery of types 1 and 2, found in the lower level, was used in the cities from which, according to the legend, the besieging forces came.

(C) Several pieces of stone from a lower-layer wall have been found incorporated into the remains of a building in the middle layer.

(D) Both the middle and the lower layer show evidence of large-scale destruction of habitations by fire.（A）

(E) Bronze ax heads of a type used at the time of the siege were found in the lower level of excavation.

What's wrong with (C)????

I think (c) means middle-layer and low- layer at the same period

It means correct answer

thanks for sharing your opinion!!

19题是不是因为siege occurs before destruction？？

20题是不是因为底层的东西早于中层的东西早于上层的东西？？

这些好像都是默认的assumption，是吗？？

没看明白20题,A和问题有什么关系啊？

没人？
