Question

consider this claim:
daylight saving time should be abolished.
which is the strongest evidence to support the claim?
turning the clocks forward in the spring means an extra hour of daylight in the evenings, which might motivate people to do more active outdoor activities after work instead of sitting around inside.
an economics professor noted that his students often seem less alert in class during the week following daylight saving time because the time change throws off their sleep schedule.
a study from the national bureau of economic research found that turning the clocks forward in the spring increased energy consumption, contradicting the popular belief that daylight saving time saves energy.

Explanation:

The claim is that daylight saving time should be abolished. Strong evidence needs to directly undermine the purpose or show harm of daylight saving time. The first option supports daylight saving time (extra outdoor activity). The second is anecdotal (professor's observation of students). The third is a study from a reputable institution showing daylight saving time increases energy consumption, contradicting its supposed energy-saving benefit—this directly challenges its core rationale, making it the strongest evidence.

Answer:

A study from the National Bureau of Economic Research found that turning the clocks forward in the spring increased energy consumption, contradicting the popular belief that daylight saving time saves energy.
