Question

read the opinion below.
getting sick with the flu is worse than having the common cold.
select the reason that best supports this opinion.
washing your hands frequently is the best way to avoid getting a cold or the flu.
the flu usually comes with a higher fever than a cold does.
the common cold usually lasts much longer than the flu does.

Explanation:

The opinion is that the flu is worse than the common cold. A higher fever (a more severe symptom) associated with the flu directly supports the idea that it is worse. Washing hands is a prevention method (not about severity) and the cold lasting longer (if true) would suggest the cold is worse (contradicting the opinion).

Answer:

The flu usually comes with a higher fever than a cold does.
