1. French wines taste better than American wines -- it is incorrect it seems
2. John ran as fast as, or even faster than, Paul
i thought both of them are correct.. but latter one is correct and former one is wrong
comparison confuses me always.. kindly help!
Who told you it was incorrect? You are understandably going to be confused if some book or friend is giving you wrong advice.
It could have been an American who thinks that American wines taste better than French wines.
Otherwise, there is nothing wrong with the sentence.
what about the second sentence?
John ran as fast as, or even faster than(,) Paul
The sentence is fine, 2nd comma not required.
It would be better as:
John ran as fast as, and even faster than Paul.
There may be some question, or context or other where 'as fast as, or even faster' would be a suitable reply/response; but as it stands, 'and' makes more sense.
