Travel Agent: In the book travelling abroad, the author claims that European hotels are better designed than American hotels. This claim is justified by a thorough comparison of 25 populat European hotels and 25 popular American hotels. In this comparison, none of the American hotels were as complexly designed as any of the European ones.

The travel agent's argument is most vulnerable to which of the following criticisms?

a) The hotels reviewed by the book may be those that best serve its proposal.
b) Hotels can be judged by other merits besides design
c) The author of the book has written other books favoring European travel.
d) Hotels in other parts of the world may be better designed than those in Europe.
e) Someone who hasn't been to Europe might not appreciate hotel design.


OA is A - Why? After all, A) supports Travel Agent's argument. Travel agent tends to disagree with the author of the book. How could A) be a criticism of his argument?

I am unsure about all the five answer choices.


Thanks
