Transportation expenses accounted for a large portion of the total dollar amount spent on trips for pleasure by residents of the United States in 1997, and about half of the total dollar amount spent on transportation was for airfare. However, the large majority of United States residents who took trips for pleasure in 1997 did not travel by airplane but used other means of transportation.

If the statements above are true, which of the following must also be true about United States residents who took trips for pleasure in 1997 ?

Most of those who traveled by airplane did so because the airfare to their destination was lower than the cost of other available means of transportation. Most of those who traveled by airplane did so because other means of transportation to their destination were unavailable. Per mile traveled, those who traveled by airplane tended to spend more on transportation to their destination than did those who used other means of transportation. Overall, people who did not travel by airplane had lower average transportation expenses than people who did. Those who traveled by airplane spent about as much, on average, on other means of transportation as they did on airfare.

Half on airfare; Most use others 问题类型
推理题 推理过程
已知机票花费占交通总花费近一半，然而多数休闲旅行者不坐飞机。这意味着坐飞机的人花费较高，不坐飞机的人整体平均交通花费相对较低。 选项分析
A选项：文中未提及坐飞机的人选择飞机是因为机票价格比其他交通方式低，属于无中生有，排除。 B选项：文中没有提到其他交通方式不可用导致人们选择飞机，无中生有，排除。 C选项：题干没有关于每英里花费的比较信息，无法推出，排除。 D选项：因为机票花费占总交通花费约一半，且多数人不坐飞机，所以整体上不坐飞机的人平均交通花费比坐飞机的人低，该项可以推出，当选。 E选项：题干没有给出坐飞机的人在其他交通方式和机票上花费的比较信息，排除。
