In the given question, a sentence is divided into four parts and given in the alternatives (A), (B), (C), and (D). There is an error in one part. Choose the alternative containing that part of the sentence that has the error. Choosing the alternative with the error will be the answer.
It is 14:25 hours now and the arrival time of the train is 14:30 hours, so we have to wait for five more minutes, and the train is going to come to the station within five minutes.
Show answer & explanation
Correct answer: D
Explanation
Redundancy (Tautology): The sentence has already established in Part (B) and Part (C) that the arrival time is 14:30 (5 minutes from now) and that the speakers have to wait for five minutes.
Repeating that the train is "going to come within five minutes" in Part (D) is logically redundant and makes the sentence grammatically cluttered.
Furthermore, in formal or technical English (using "hours" for time), the phrasing "going to come to the station" is informal. A more precise term would be "arrive at the station."
