The correct answer is: E. approachable, less.
The sentence is about a person who preaches liberal views but is not tolerant in practice. This means that the person is not open-minded and is quick to judge others. The word “approachable” means “easy to talk to” and the word “narrow-minded” means “having or showing a limited outlook or understanding.” Therefore, the person in the sentence is not approachable and is less tolerant than almost any other person.
The other options are not as good fits for the sentence. The word “hard” does not make sense in the context of the sentence. The word “tolerant” is the opposite of the word “narrow-minded” so it does not make sense to say that the person is tolerant but is also narrow-minded. The word “ambitious” does not make sense in the context of the sentence. The word “acceptable” does not make sense in the context of the sentence.
