a
The number of █████ ███ ███ ████ █ ██████ ██ ███████ ██ ████ ███████ ██ ████ ████████ █████████ ██████
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 ████ █████ █████████ ██████ ████ ██ ████ ████ ████ ██ ██ ████
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 █ █████ ██████ ████ ██ ████████ ███ ███ ███████ ██ ███ █████ ███ ██████████
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 ██ ████ ████ █████ █ ███ ██ █████ ██ █████ █ █████████ ██ █████ ████████ ██ ███████
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 ████ █████ ██ █████ ██████████ ████ ████ ███████████ ████ █████ ███ ███ ████ █ █████ ██████ █████
This could be true; the stimulus does not give any information that compares how efficiently people work under different payment systems.
