Metal rings recently excavated from seventh-century settlements in the western part of Mexico were made using the same metallurgical techniques as those used by Ecuadorian artisans before and during that period. These techniques are sufficiently complex to make their independent development in both areas unlikely. Since the people of these two areas were in cultural contact, archaeologists hypothesize that the metallurgical techniques used to make the rings found
in Mexico were learned by Mexican artisans from Ecuadorian counterparts.
Which of the following would it be most useful to establish in order to evaluate the archaeologists' hypothesis?
(A) Whether metal objects were traded from Ecuador to western Mexico during the seventh century
(B) Whether travel between western Mexico and Ecuador in the seventh century would have been primarily by land or by sea
(C) Whether artisans from western Mexico could have learned complex metallurgical techniques from their Ecuadorian counterparts without actually leaving western Mexico
(D) Whether metal tools were used in the seventhcentury settlements in western Mexico
(E) Whether any of the techniques used in the manufacture of the metal rings found in western Mexico are still practiced among artisans in Ecuador today

Is the answer D. We want to know whether people in western mexico during the 17th century were aware of the techniques to develop such rings.
They could have either got it from Ecuadorian counterparts. If this is the case, then mexicans would have never known to make rings.

Option C,d and E are not relevant.
Options A and C are close.
In order to learn the technique,metals must be available in Mexico.
If option C is true,artisans from mexico learn technique from Ecuadorian counterparts without leaving mexico itself.this leads to question whether metals imported from Ecuadorian.
Option A evaluate this question.

What's the problem with 'D'? If metal tools were not used then metal rings cannot be made. Option A just says if metals were exchanged or not but the question talks about technique.

Question states,
"archaeologists hypothesize that the metallurgical techniques used to make the rings found in
Mexico were learned by Mexican artisans from Ecuadorian counterparts "
Option C states,
"western Mexico could have learned complex metallurgical techniques from their Ecuadorian
counterparts without actually leaving western Mexico" Without leaving or leaving won't help to evaluate the hypothesis which is indeed repeated in the option choice C
However, A clearly helps to evaluate the hypothesis.

I agree with ankurmit above - that's exactly the reason why A is relevant. In order to reach the conclusion that the Mexicans learned how to make the rings from the equadorians, the argument must assume that the rings were actually made by the mexicans themselves. If metal goods were traded from equador to mexico, it is possible that the rings found are Ecuadorian in origin, not Mexican, in which case the mexicans did not have to learn the techniques at all. However, if metal objects were not traded, then this would strengthen the conclusion that the rings were made locally, and the techniques would then have to be learned. Thus, knowing A strengthens or weakens an assumption made by the argument, and is the least worst of the answer choices given in that it has some relevancy to the question.ankurmit wrote:Metal rings recently excavated from seventh-century settlements in the western part of Mexico were made using the same metallurgical techniques as those used by Ecuadorian artisans before and during that period

This is not obvious at first glance, but rather reached by elimination. At first I eliminated all five answer choices as irrelevant, and only then took another look at what A actually means. The other answer choices have even worse flaws, making them irrelevant:
B land or sea has nothing to do with anything.
C would've been fine without the "leaving mexico" part - there's no reason to assume that the mexicans learned the techniques by email, and the argument perfectly allows mexicans to go to Equador. so even if the mexicans were able or not able to learn the techniques remotely, this tells me nothing of whether they did actually learn them or not.
D requires a knowledge of metallurgy not likely to be required on the GMAT - perhaps it is possible to make metal rings without metal tools to make them? I don't know, and the GMAT is not likely to require me to know this obscure knowledge. If it was important, the argument would've said something about it - It's a trap answer confusing rings with tools.
E we care not for the present, but for the 7th century.

Hi Geva,
I personally agree with your thoughts regarding (A). So do you mean the official explanation is incorrect, despite that there is no dispute on the correct answer (A)?
According to official explanation:
If the answer to (A) is yes ---strengthen
If the answer to (A) is no ---weaken
According to your explanation (which I think is more convincing than OE)
If the answer to (A) is yes ---weaken
If the answer to (A) is no ---strengthen

In my opinion, the choice A is correct because it could strengthen or weaken the premise, i.e. the people of these two areas were in cultural contact.
If there were trades, then the choice strengthen the premise, thereby strengthening the conclusion.
If there were not any trade, then it somewhat weaken the premise. The choice eliminate a way that could lead to culture contact between the two countries. R
I find the question tricky because it focus on evaluating the premise rather than conclusion or assumption as other evaluate questions.
---
I do not think whether who are the creators of the ring is important. The conclusion is about who are the creators of the techniques that are used to manufacture the ring.
