Hello; I'm 'The French',
I try on this website the quiz which is called Enough-2 (beginner level), but I'm made two mistakes (number 23 and 24).
I think I know the English grammar rule for the use of enough, but I saw the correction, and I still have not understand the answers who is giving by the correction.
I write phrase number twenty-three below:
23) "He's bored because he doesn't have enough to do.(why it's not to do enough?)
The rule is :
Adjective or adverb + enough or enough + noun
To do is the infinitive form of do, it's not a noun, why in this case the good answer is that.
Thank for you help, have a nice day.
"enough" is a pronoun here.
Have you had enough (= to eat)?
