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 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?



(A) 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.


(B) Most of those who traveled by airplane did so because other means of transportation to their destinations were unavailable.


(C) 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.


(D) Overall, people who did not travel by airplane had lower average transportation expenses than people who did.


(E) Those who traveled by airplane spent about as much, on average, on other means of transportation as they did on airfare.

Let’s look at the info provided


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

about half of the total dollar amount spent on transportation was 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.


What can we infer from the above stimulus?


(A) 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.


How do we know about this? We do not know why they chose to travel by airplane. Eliminate



(B) Most of those who traveled by airplane did so because other means of transportation to their destinations were unavailable.


Same as A.  We do not know why they chose to travel by airplane. Eliminate


(C) 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.


We know that the overall transportation charge was more. But to infer that they spent more per mile is extreme.


(D) Overall, people who did not travel by airplane had lower average transportation expenses than people who did.


- half of the total dollar amount spent on transportation was airfare

  • 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.


From this, we can infer that people who did not travel by airplane had lower average transportation expenses than people who did.




(E) Those who traveled by airplane spent about as much, on average, on other means of transportation as they did on airfare.



We don’t how much they spent on other means of transportation. Eliminate
