Take the smallest prime integers and play. 2*2*2*2*2*2 =64 Since if you times by 2 once more, it will be 128, which is THREE digits instead of the two digits asked for in the question. so that's one. let's try the next prime up from 2, which is obviously 3. 2*2*2*2*2*3=96 so that's two. if you multi...

So, for the second question, we have both statement (1) and (2) repeating the information given in the question. For those questions, do we just look at the 2 statements' agreeing with the question as a confirmation of the question? Hence, D? Or do we have to look at the fact that they're different ...

IMO E, supported directly by the following sentence in the passage: Each country was also to notify the six other countries when it had completed its action.

The only beef I have with (D) is that the GMAT does not like to use "extreme" adjectives. E.g, "impossible" could've been replaced with "difficult" in order to make (D) a more viable choice. But I see where people are coming from when they choose (D). It is a good answer.
