A taxi driver earns a flat amount per passenger plus a charge per mile driven. Based on current gas prices, she estimates that approximately 35 percent of the money she earns per mile driven will be spent on gasoline. However, for the past two weeks, the taxi driver has in fact spent about 45 percent of the money she earns per mile on gasoline. Yesterday, while performing routine maintenance on her car, she noticed that her tires were somewhat underinflated, which would negatively affect her car’s gas mileage.

Of the following claims, which is most strongly supported by the passage?

A. The taxi driver’s gas mileage has steadily gotten worse over the past two weeks.
B. Even before discovering the issue with her tires, the taxi driver had reason to believe that on at least some nights her car’s gas mileage was worse than anticipated.
C. When her car is in perfect maintenance, the taxi driver spends 35 percent of the money she earns per mile on gasoline.
D. The taxi driver’s gas mileage fluctuated greatly over the past two weeks.
E. The increased proportion of earnings spent on gasoline decreased the taxi driver’s overall income.

Of the following claims, which is most strongly supported by the passage?

Look for a must be true choice.
A. The taxi driver’s gas mileage has steadily gotten worse over the past two weeks.
Can you prove the highlighted part based on the argument ? I don't think so.

B. Even before discovering the issue with her tires, the taxi driver had reason to believe that on at least some nights her car’s gas mileage was worse than anticipated.
Look closely at the highlightedpart. It's talking about money per mile. So definitely the mileage is affected.

C. When her car is in perfect maintenance, the taxi driver spends 35 percent of the money she earns per mile on gasoline.
The premises says she ESTIMATED the figure. You can not be sure about this.

D. The taxi driver’s gas mileage fluctuated greatly over the past two weeks.
Same as A

E. The increased proportion of earnings spent on gasoline decreased the taxi driver’s overall income.
Well, the overall income didn't change for sure; her profits did.

B is correct !

Hi I was able to eliminate other 4 wrong options, but couldn't understand why B was right. By your reasoning, still couldn't understand how driver would have known before the maintenance that he is loosing on mileage.

Hey,

Prior estimate: 35 percent of the money she earns per mile driven will be spent on gasoline.
For last 2 weeks: spent 45 percent of the same.

Since she is spending more money on gasoline so either she is driving more distance or using more liters of gasoline to drive the same distance.

Former case can be rejected as the estimate is already based on 'per mile'. So, it must be that the engine is sucking more gasoline per mile i.e the mileage has gone worse. Now, the mileage could have gone worse steadily every night or to a one time extreme that caused a 10 percent decrease. In either case, the taxi driver had reason to believe that on at least some nights her car’s gas mileage was worse than anticipated.
Hope that makes sense.
