Question

Only one of the sentences below is CORRECT. Which one is it? A) In my opinion they are much too young to get married. B) On my opinion they are too much young to get married. C) In my opinion they are not enough old to get married. D) On my opinion they do not have age enough to get married.

Answer 1

Letra C se aproxima mais do correto.

Answer 2

The correct answer is Alternative A.

However weird this might sound to non-natives, the much too structure is grammatically correct. Much too modifies an adjective and an adverb, whereas too much modifies a noun and a verb. As you might know, young is an adjective, so it fits the structure pattern.

Semantically, they mean the same: an excessive quantity.

Regarding the other alternatives: B is wrong because the expression is "in my opinion" and it doesn't follow the much too + adjective structure; C would be correct had it been written as "they are not old enough"; D same as in B, plus "do not have age enough" is not proper grammar.
