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.

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.

I believe if we may prove that lower layer and middle layer had sae features we will be able to weaken the conclusion.

The archaeologists are basing their information on which layer the siege can be in with respect to the artifact that is found. What can greatly undermine this thought process: If the artifact were moved around around by an outside force. If the artifact were indeed initially in the highest layer it would have been possible for the siege to have taken place in the middle layer. If something moves the artifact to the bottom of the middle layer, our assumption that the siege took place at a layer lower than the middle layer would be incorrect. Therefore (A) is the best answer.

Can any one comment ...Why A is better than D.??
