Official ExplanationRead and look for errors:The sentence features two complete clauses. When this is the case, check that exactly one connector connects the two clauses. Additionally, the relationship the connector conveys must make sense in the context of the sentence. Here, the single connector "but" correctly conveys the contrast between the two clauses.
Scan and group the answers:Choices (A) and (B) use the connector "but." Choice (C) uses "with" and choices (D) and (E) use "while." Additionally, choices (A), (C) and (D) end with the name "Ms. Cerrato", while choices (B) and (E) end with the pronoun "her."
Eliminate wrong answers:Choice (C) can be eliminated because the connector "with" does not convey the contrast between the two clauses.
Choices (B) and (E) can be eliminated for using the ambiguous pronoun "her", which could refer to either of the two authors.
Choice (D) eliminates the verb "was" between "one" and "a". Removing the verb from the clause makes the thought incomplete and makes (D) incorrect.
This leaves Answer Choice (A) as the answer, because the sentence is correct as written.
TAKEAWAY: If a connector is used in a sentence that contains two independent clauses, there must be one and only one such connector and it must relate the two clauses in a logical manner.
