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. 

The use of the simple pronoun "him" is confusing in this sentence, as it is unclear exactly who the pronoun refers to, the subject or some other person. The best way to clear this confusion up is by using the reflexive pronoun "himself" to refer back to the subject. Thus, the correct answer choice is "to pamper himself with nice meals on the road."

This phrase must have a pronoun and a possessive pronoun which refer to all three individuals: "we" and "our."

In the answer choice "she always goes to our favorite restaurant," the pronoun “she” does not agree with the subject of “Sheila, Veronica, and I”—it should be “we.”

In the answer choice "we always go to her favorite restaurant," the possessive pronoun “her” should be “our,” as it refers to a restaurant preferred by all three subjects. Though this sentence could be correct, it is not the best option because “her” is not specified.

In the answer choice "we always went to our favorite restaurant," the verb “go” must agree with the present tense of “spend,” so it is incorrect.

In the answer choice "they always go to their favorite restaurant," the pronouns “they” and “their” exclude “I” as a subject, so it is incorrect.

The use of "him" at the end of the sentence is confusing and awkward, as it is not clear to whom the pronoun is referring. Changing the simple pronoun to a reflexive pronoun allows the pronoun to refer back to the subject of the sentence clearly. Thus, the correct answer choice is "that only benefitted himself."

The sentence is faulty because it uses a pronoun with an ambiguous antecedent. The reader can't be sure who either "they" or "them" is referring to -- the bankers or the computers. The error can be fixed by rearranging the sentence so that "they" is followed by the clarifying subject "bankers."

This is an example of an ambiguous pronoun. The "him" in "to give him away" in the original sentence could be applying to either the dog or the cat, so we must make clear that it is one or the other.

The sentence implies that a single female author wrote the Scivas; however, the first clause mentions two women. To resolve the potential ambiguity that "her," which could refer to either Teresa or Hildegard, would introduce, the name of the author must be used rather than a pronoun. "They," which is commonly used in vernacular English to refer to a subject whose gender is either unknown or not specified, is only used to refer to plural antecedents according to the strict rules of standard written English. Finally, as only one work (the Scivas) is mentioned in the passage, the pronoun referring to it must also be singular.
