标题: 大全上的一道题。
Questions 19-20 are based on the following.
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.
(E) The pottery of type 3 was imported to the city by traders.
OA：C

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

OA：A

不懂第20题，为啥C不对呢。

明白鸟，我来自问自答了。

20题A是说有动物捣洞，上一层的物品会掉到下面一层。也就是说如果古迹分为3层。顶层的东西会掉到中层来，从而weaken了19题的结论。

20题我也选的C
Several pieces of stone from a lower-layer wall have been found incorporated into the remains of a building in the middle layer.

关于C，我后来的理解是，新的朝代有可能用旧时代墙上的石头建造他们新的建筑，因此C不会削弱结论。
但A说的是小动物捣洞，可以导致上层的东西，如pottery of type 3从顶层掉到中层。这样的话就会削弱结论了。
感觉A难就难在并没有指明上层遗迹的存在。可是，既然文章说有中层了，必然就会有上层。

其他网站的解释，跟我说的一样。（怕解释错了，验证了一下）

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.

Gerbils can distort the evidence. If the pieces of pottery of later period falls into middle layer, then perspectives of archaeologists can get distorted. My answer.

你说的是对的。回头看看还是A比较sounds.
C说的several剩下的旧的stone去砌新墙还是说得过去的。
A的如果新的掉到旧的里（也就是many or most）就说不过去了。
强弱的问题，several不如many or most

我想说这道题没有conclusion sentence，题目也是要让攻击evidence。
