Taxi drivers, whose income is based on the fares they receive, usually decide when to finish work each day by setting a daily income target; they stop when they reach that target. This means that they typically work fewer hours on a busy day than on a slow day.

Summary
Taxi drivers’ income is based on their fares.
They often decide to finish work when they reach a daily income target.
They tend to work fewer hours on busy days than on slow days.

Notable Valid Inferences
Taxi drivers get more money per hour on busy days than on slow days.

A
The number of hours per day that a person is willing to work depends on that person’s financial needs.
This could be true. The stimulus does not give any indication on what considerations go into the drivers’ income targets. It could be the case that one’s financial needs determines their income target.
B
People work longer when their effective hourly wage is high than when it is low.
The stimulus provides clear evidence against this. The stimulus says that drivers stop working when they meet their income target; they will reach their income target more quickly when their hourly wage is high, so they will work fewer hours on these days.
C
Workers will accept a lower hourly wage in exchange for the freedom to set their own schedules.
This could be true; the stimulus does not give any information to indicate what wages they will accept in exchange for freedom over their schedules.
D
People are willing to work many hours a day in order to avoid a reduction in their standard of living.
This could be true; the stimulus does not contradict this. We don’t know how many hours “many” hours means, and we don’t know whether or not taxi drivers are hitting this threshold of “many hours.”
E
People who are paid based on their production work more efficiently than those who are paid a fixed hourly wage.
This could be true; the stimulus does not give any information that compares how efficiently people work under different payment systems.

Further Explanation

The key to this question is understanding what an "effective hourly wage" means.

If you get paid a total of $100 over the course of a day, what's your "effective hourly wage"? Well, that depends on how many hours you worked. If you worked 1 hour to make that $100, then you're "in effect" getting paid $100/hour. If you worked 10 hours to make that same $100, then you're "in effect" getting paid $10/hour ($100 divided by 10 hours).

Understanding this helps to make (B) clearer as the correct answer choice.
