KAPLAN OFFICIAL EXPLANATION
(C)
Step 1: Read the Original Sentence Carefully, Looking for Errors
The underlined portion begins with the subject “several people” and the verb phrase “have designed.” The verb is in the present perfect tense, so it should refer to an action that started in the past but is still occurring in the present. However, the act of designing occurred in the past and finished before another past event happened(Edison receiving his patent). Thus, this should use the past perfect tense (“had designed”) instead.
Step 2: Scan and Group the Answer Choices
(A), (B), and (C) begin with “several people,” while (D) and (E) begin with “similar light bulbs.” Either subject could be acceptable. It’s more useful to note that (A) has the erroneous “have” paired with “designed,” while (B) and (E) change “have” to “having,” and (C) and (D) change it to “had.”
Step 3: Eliminate Choices Until Only One Remains
(A) contains the mistaken “have designed,” so eliminate that first. (B) and (E) change the phrase to “having designed” and “having been designed,” respectively. However, the -ing form of “having” leaves the sentence incomplete, without an active verb. That eliminates (B) and (E). The remaining choices correctly change the verb to “had designed.” (D) changes the subject, which could be okay but seems suspiciously unnecessary. Then (D) uses the present tense verb “receives” at the end, despite the fact that the rest of the sentence puts all actions in the past. That eliminates (D). (C) is correct. This choice provides a past perfect verb for the designing and creating that happened before Edison received his patent. Read this choice back into the sentence to verify that it is correct:
While Thomas Edison is often credited with inventing the incandescent light bulb, historians note that several people had designed and created similar light bulbs before Edison received his patent.
