This exercise tests your understanding of basic grammar rules.
1One day people will ............... colonize Mars.
Wrong!
After "will", use the base form "be able to" to talk about future ability.
2What have you ............... to find out?
Wrong!
The present perfect form is "been able" after "have".
3I am very much interested in ............... to paint.
Wrong!
After "interested in", use the gerund "learning".
4You don’t look happy ............... me.
Wrong!
After "happy", use the infinitive "to see" to give the reason.
5That dress is new, ...............?
Wrong!
A positive statement usually takes a negative question tag, so the correct tag is "isn't it".
6It was ............... that I didn’t go out.
Wrong!
With "so" before an adjective and a singular countable noun, the correct order is "so warm a day".

The adverb "madly" modifies the expression "in love".
8She was ............... injured in the crash.

The fixed expression is "Feel free" when giving permission or encouragement.
