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.

VeritasKarishma can u please explain me this CR.How to find conclusion ?


"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."

They are excavating the middle and lower layers of a mound. No mention is made of the upper layer but we can assume there must be one since there is a "middle" layer. Depending on where they find the remains, they can find the location of siege and destruction.


"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."

So the bottom of the middle layer has stuff from the later period (after the siege and destruction). One would naturally assume that the siege must have happened at the time of the lower layer then and the middle layer must have formed after the destruction. That is why the middle layer contains artefacts from the later period. Hence, destruction may not have happened at the time of the middle layer.

Before we move on to the options, note why excavating layers can tell us when the destruction took place. The mound would have formed over centuries. The lower layer would contain remains of life and other elements which were present during that time. Over time, dirt would settle and higher layers would contain remains from a later period. so the lower you dig, the more you can find about how life was in the older days.

Now let's go on to the options. We need one that weakens the force of the evidence i.e. that tells us that the destruction may not have happened in the lower layer or may have happened in the middle layer.

(A) Gerbils, small animals long native to the area, dig large burrows into which objects can fall when the burrows collapse.
This brings into question the period in which the siege happened. It is possible that the siege happened in the middle layer and the artefact was in the upper layer but a gerbil dropped it in the bottom of the middle layer. Then the period of the siege cannot be guessed. So the force of the given evidence is weakened.

(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.
This fortifies the idea that the siege took place at the time of the lower level. We need to weaken the evidence but this in fact strengthens it somewhat.

(C) Several pieces of stone from a lower-layer wall have been found incorporated into the remains of a building in the middle layer.
Stones of lower layer have been found in middle layer. This doesn't impact our siege/destruction timeline as such. Did the siege take place at the time of the lower layer and the wall was damaged in it? How did the stones reach the middle layer. Too nebulous.

(D) Both the middle and the lower layer show evidence of large-scale destruction of habitations by fire.
Two layers show evidence of destruction by fire. The time of the destruction is not clear then.

(E) Bronze ax heads of a type used at the time of the siege were found in the lower level of excavation.
This fortifies the idea that the siege took place at the time of the lower layer. We need to weaken the evidence but this in fact strengthens it somewhat.

Answer (A)

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).

Hi Skywalker18,

In my opinion, this is a pretty bad question. You are correct -- no conclusion here is given. It seems that this question was written as a follow-up to a question asking about the conclusion of the argument (which would not happen on the real GMAT). To answer this, we need to first determine the most likely conclusion, which is that the middle layer does not represent the period of the siege. Given that, A is the best answer, since it provides an alternate reason for why pottery from after that period would be seen in the middle layer. But again, in my experience this type of question would not be asked on the GMAT.

Hope that helps!
-Carolyn

Anyone has a opinion on the quality of this question? CR is usually one of my strongest sections but after reading the prompt three times I still could not properly comprehend what is even in question.

It feels like some minor background knowledge could be needed to come up with a proper solution.

Any thoughts?
