Archaelologists
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.

1. 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 the traders.

2. 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 axheads of a type used at the time of the siege were found in the lower level of excavation.

第一题C，第二题A

Evidence:

1. some pieces of pottery of type 3 are found in middle layer

2. these potteries indicate a period latter than the destruction, or the legendary siege

Hinted assumption:

The lower the layer is, the more ancient the remainings are.

Q1: ask for conclusion

The middle layer reflects the period latter than the destruction on the basis of linking the potteries excavated and those indicative.

Q2: ask for weaken

In an attempt to weaken the apparent conclusion, just as Q1 shows, we must question whether the findings, those potteries, is representative of the remainings in the proper period of history. A, the best answer, gives the profound reason that it is highly possible the potteries found are those latter ones, which have been sinking for years through the burrows.
