Previous Year Questions

(A) completes subject-verb phrase and serves as the main clause of the sentence. It logically introduces the action. (C) phrase adds more context to the main clause. It explains where he was going and sets up a reason for why he had to take the bus. (E) continues the explanation started in (C). It provides one of the reasons for why he couldn't use another means of transport. (B) introduces additional information about another reason why he previously did not need to take the bus. (D) completes the thought introduced in (B) by explaining that his usual source of transportation (his friend's help) was unavailable.

The correctly arranged sentence is: "He had to take the bus to his office because he had never learned to drive and his friend, who used to give him a lift, was on vacation."

Thus, ACEBD is the only logical and grammatically correct sequence.
