Hi!
Can you explain the answer of question? I just can't understand why the correct answer is C

I agree with your assessment, jalolbek, and I question the validity of the source. Since the passage provides no information on the proportion of English school children that has never travelled abroad, and we have no pertinent information on school children from other nations, how are we in a position to state that the sample is unrepresentative? (For instance, what if 90 percent of English school children had not travelled abroad, and the same were true of school children from other countries? Then the sample would seem quite representative.) Although I am not keen on either (A) or (B), I cannot point out a fatal flaw in either (D) or (E). Since the passage has not led me to believe in the inevitable conclusion given at the end, (D) seems reasonable; it also takes for granted that the English are poor at learning foreign languages. That is, I am not sure that an excuse for the poor performance of English school children at learning foreign languages from the first line of the passage constitutes proof that the English are poor at learning foreign languages. Still, I do not have a definitive answer. IanStewart, any thoughts?

I typically discourage students from studying third-party material because some of it is loosely constructed and will likely lead to confusion rather than clarity. GMAT™ CR logic is linear in nature and easier to follow, even though there are, of course, some difficult questions. I would move on from this one without too much of a thought, to be honest.
