Hey, guys! here is an official explanation.
The original sentence expresses the main verb “attended” in the past tense and the two subordinate actions in the "-ing" form. This construction correctly indicates that “receiving” and developing” followed as a consequence of Einstein’s attendance of “the Swiss Federal Polytechnic School in Zurich.”
(A) CORRECT. This answer choice is correct as it repeats the original sentence.
(B) This answer choice breaks the correct parallelism of "receiving" and "developing" present in the original sentence.
(C) This answer choice expresses all the verbs in the underlined portion in the same form: “attended,” “received,” and “developed.” This change alters the original meaning of the sentence by making these actions independent and sequential rather than demonstrating that “receiving” and “developing” occurred as a consequence of the fact that “Albert Einstein attended the Swiss Federal Polytechnic School in Zurich.” Further, this answer choice introduces the redundant pronoun “he,” which unnecessarily repeats the subject of the sentence and breaks parallelism.
(D) This answer choice makes "attended" and "received" parallel, leaving "developing" as a subordinate action. This change alters the meaning of the sentence, as described above in the explanation for choice (C). Moreover, there is no "and" between "attended" and "received," as there should always be between the items in a two-item list.
(E) This answer choice creates an incomplete sentence that lacks the main verb and consists merely of a series of "-ing" forms: “attending,” “receiving,” and “developing.”
