OA: A

My question: Can someone explain the reason for A being the right answer ? I chose A over E because it *sounded* right. (You can say it was a guess)

Also, I would also like to know about the difference in usage between 'enough to' vs 'enough for'.

In B C and D the issue is "IT"

Firstly is has no antecedent and secondly when used as a subject the sentence becomes indirect and longer.

between A and E

A expresses meaning more clearly i.e.the license enables to drive

E does not express this thing

Umm.. You say that "A expresses meaning more clearly i.e.the license enables to drive "... but doesn't the sentence imply the exact opposite - that a driver's license is not enough ?

Err...yes I made a typo mistake



But I think you have got the main idea

A. A driver's license in one country is not always enough to enable a person to drive in another country legally.

We need a subject e.g. a person in the sentence

E. A driver's license in one country is not always enough for driving in another country legally.

The subject is missing here (a driver / person needs to be mentioned in the passage)
