Hi

First of all: avoid to confuse you by a gmat question and try to understand the situation at end; trying to identify the premise and conclusion

What we know:

1) towns decimated by volcanic ashes

2) the conseguences is due to a volcanic activity that destroyed all in 160 BC

Now, here the question:

A) coins minted before 160 and no after.....this could explain and at the same time reinforce the archaelogists hyphotesis that the destruction accoured in 160 BC (is what we looking for eventually)

B) piece of gold were found before and after 160 (is all destroyed by volcano how we could have something produced after 160 by human being ?? )

C) This not explain us WHY the destruction and people decimated by volcanoes: isneutral like answer and it doesn't neither to affect our conclusion nor our argument at all. This option tells nothing about, the eruptions were near the island but nothing more: they could have affected the entire situation but even at all.

D) and E) similar in reasoning to B

Hi Ankit546

I'd imagine that you're trying to differentiate between a) and c), as the other 3 weaken the argument. I agree with carcass above, and he / she uses the same logic that I did.

When I see two possible answers for strengthen questions, I look at a couple of other elements:

1) How tightly is the answer bound to strengthen the argument? In c) above the wording suggests that it strengthens the argument by talking about eruptions in the correct timeframe. But it is not bound to strengthen the argument; it could be that the eruptions where not related to any events on the island so in that sense it adds nothing (particularly if you consider that there are already signs of volcanic activity in the region). In a) the final scenario (i.e. argument + answer) gives evidence of volcanic activity and a very precise time, both in the correct region.

2) What are the elements of the conclusion that needs proving / strengthening? The conclusion is that a village was destroyed by a volcano in 160BC. The argument supplies evidence for the destruction of the village by volcanic ash but gives nothing for the time (160BC) of the eruption, or its location. Answer c) talks about volcanic activity which is attractive but not necessary, the time (which is necessary) but not the location. Answer a) gives the time and the location. It doesn't give the method of destruction, but this is ok because the argument already contains this evidence.

Hope that helps

B.

Ya, when i was trying to solve this problem, I thought that premise is mainly about a time frame and volcanic activity. So, I thought "C" might just win it. But a great explanation provided by both you and carcass.

The explanation definitely helped

Cheers,

Ankit
