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.

archaeologists-seeking-the-location-of-a-legendary-siege-and-44157.html


looks like a very tricky question...what do we have to weaken? from the given argument, it might be inferred that the archaeologists are digging on the right site...
all but A actually support this idea, whereas A says that pottery might have gotten in the lower levels by accident.

The conclusion here is that the middle layer doesnt belong to siege and destroyed city.
Evidence is that there exist type 3 pottery in middle layer.
A says that its possible that these type 3 pottery is among the objects fell in the areas dig by Gerbils. This definitely can weaken the conclusion.
B mentions lower level, so cant weaken the conclusion.
C shows middle and lower layers may be related but doesnt hurt the conclusion. they both could be part of siege city or couldnt.
D says destruction caused by fire but no evidence of siege.
E again mentions lower level, so cant weaken the conclusion.

Here the conclusion is 'the bottom of the middle layer contains some pieces of pottery of type 3, but the lower layer does not'.

We need to weaken this conclusion, showing that the bottom of the middle layer does not contain some pieces of pottery of type 3 or that the lower layer contains pottery of type 3.

Option A, clearly says that pottery of type 3 is not belong to the middle layer. It is from upper layer. So A is winner.

We are not provided with a conclusion, so we have to draw one based on the evidence.

Evidence: Bottom of middle layer contains pottery 3. Pottery 3 is made AFTER the destruction.

We can infer that usually the deeper the level = the older the time period. Since as we move forward in time, we generally build up on things. So, the city was probably destroyed around the lower layer, or in the middle layer but beneath where the pottery was found.

Question: What casts doubt on the Type 3 pottery in the middle layer/destruction of city inference?

Prediction: If the pottery was moved around — if the location doesn’t represent the time period accurately.

A – decent choice, shows pottery could’ve been moved
B – doesn’t comment on Type 3 pottery
C – this implies at some point the middle-layer people used the wall below them to build up — but doesn’t show that the pottery could have moved down or up
D – Fire is totally irrelevant
E – “at the time of the siege” is vague — and this doesn’t relate at all to the pottery evidence

The correct answer is (A).
