On her way to work today, Wendy paid one dollar more to fill her car's gas tank than she paid one week ago to fill the same tank.

A) Wendy's car is leaking gasoline.
B) The price of gasoline has gone down.
C) Wendy needs her car for transportation.
D) Wendy took a trip out of town this week.
Is it c?

No.

The most logical answer is that the price of gas has gone up. However, we can't tell if it's A or D.

You haven't been given enough information.

To determine the correct answer, we need to analyze the given information. Wendy paid one dollar more to fill her car's gas tank today than she did one week ago. Based on this information, we can eliminate options A (Wendy's car is leaking gasoline) and D (Wendy took a trip out of town this week) since they do not directly relate to the cost of filling the gas tank.

Now, let's consider options B (The price of gasoline has gone down) and C (Wendy needs her car for transportation). Since Wendy paid more today than she did one week ago, it implies that the price of gasoline has increased, not decreased. Therefore, option B can be eliminated.

This leaves us with option C (Wendy needs her car for transportation) as the correct answer. The fact that Wendy is still paying to fill her gas tank suggests that she requires her car for commuting purposes or other transportation needs.
