Which sentence gives a reason that supports the writer's
claim?
(1) The school tardiness policy needs to be revised.
(2) Students should not be punished for
circumstances that are out of their control. (3) For
instance, the city buses tend to run late in the
wintertime. (4) Students should not be forced to
wake up an hour early just to be sure that they're
not five minutes late.
Sentence three gives evidence, stating that city buses tend to run late. As opposed to the other sentences, it backs up what the author is claiming (the tardiness policy needs to be revised) other than just bulking up the claim.
