The use of "him" as the object of the sentence is extremely confusing, as it could refer to the subject or the "guru." To clarify this issue, the reflexive pronoun can be used to refer back to the subject of the sentence. The answer choice that appropriately uses the reflexive pronoun is "began to make improvements in himself."

The use of "him" at the end of the sentence is confusing. With the subject of the sentence being the third person pronoun, the object can be the reflexive pronoun and refer back to the subject. Therefore, the correct answer choice is "to the point of ignoring himself."

The use of "him" in the underlined portion of the sentence is confusing, and needs to more clearly refer to a specific individual. The use of the reflexive pronoun can make it clear that the pronoun refers to the "commanding officer." The only answer choice that uses the reflexive pronoun is "which caught up with the entire unit and himself."

The use of "him" as the object of the dependent clause in the sentence is confusing, as it is unclear if it refers to the subject of the sentence or to someone else. This confusion can be cleared up by using the reflexive pronoun that can refer back to the subject, "himself." Therefore, the correct answer choice is "enough left over so he can pay himself."

The use of "him" as the object of the sentence is confusing, as it is unclear who exactly is being referred to. As the only person mentioned in the sentence is the subject, the final pronoun needs to be the reflexive pronoun, so that it can refer back to the subject. Therefore, the correct answer choice is the only one that uses a reflexive pronoun, "an extra copy of every article for himself."

The use of the simple pronoun "him" at the end of this sentence is confusing, as it is unclear whether this refers to the subject of the sentence or to some other person. This confusion can be cleared up by making the pronoun the reflexive pronoun "himself," which refers back to the subject of the sentence. As the only answer choice to properly use the reflexive pronoun "himself," the correct answer choice is "making everything more difficult for himself."

The use of "him" at the end of this sentence is confusing and strange, as it does not properly refer back to the subject of the sentence. One might normally replace "him" with "himself," but another option, introducing "his own" as a modifier of abilities, creates a shorter and clearer sentence, so "only confident about his own abilities" is the correct answer.

The original sentence has an unclear referent. Only the choice with Velma's name clarifies that Velma is indeed the individual who crossed in the middle of the street, as opposed to the taxi driver.

The sentence has a vague pronoun reference. The use of "their" before "prescriptions" is ambiguous because we do not know if "their" refers to the doctors' or the pharmacists' prescriptions. The sentence needs to clarify to whom the pronoun refers, so the best answer choice is the one that does this, "and many pharmacists regularly complain about doctors' prescriptions."

It is unclear if the “him” refers to Kennedy or Nixon. The correct answer makes it clear with whom I agree.
