Economists compared average commute times in three neighborhoods before and after a new rail station opened.

Economists compared average commute times in three neighborhoods before and after a new rail station opened.

| Neighborhood | Before | After |
|---|---|---|
| A, near station | 46 min | 35 min |
| B, near station | 41 min | 34 min |
| C, far from station | 38 min | 37 min |

Which choice most effectively supports the claim that the largest reductions occurred in neighborhoods near the station?

Answer and explanation

Answer: A: A fell by 11 minutes and B by 7 minutes, compared with a 1-minute decline in C.

The claim is specifically about which neighborhoods had the largest reductions, and A supplies the actual size of each neighborhood's decline, showing A and B's larger drops against C's much smaller one. B and D each describe a single neighborhood's standing at one point in time, not the change the claim is about. C is true of all three neighborhoods but doesn't distinguish which had the largest reduction.
