Pick an answer to check it
wrongNot this one · the answer is BExplanation
The passage says that the company opens a route only when the number of people making reservations in the same direction reaches a certain level, so B is correct. A is wrong because the vehicles only make fewer stops on the way, not none; C is wrong because some routes are specifically for taking children to and from school; D is wrong because the passage says tickets during the rush hours for commuting have to be snapped up, not bought at any time. Therefore, choose B.
