Let’s check the answers.
(A) “one” is a pronoun. There is no switch to “you” or “we” later in the sentence so it checks out
fine.
(B) “wants” is a simple present tense verb. Check SVA. Who “wants”? One wants. We have a
singular subject (one) and a singular verb (wants) so they check fine. “them” is a plural
pronoun that refers to “others” which is also plural.
(C) “ignoring” is a gerund so check to see if it should be an infinitive instead. Yes! Ignoring
should be changed to to ignore, which is parallel to “to demand.”
(D) “even” is used correctly. It is expressing a higher degree.
Revised Sentence:
