Question

read the selection from the introduction paragraphs 1 - 4.
viruses survive better in low - humidity indoor air. humidity is a measure of the amount of water vapor in the atmosphere, so air with a lot of water vapor in it is known as humid.
what can be inferred from this selection?
a people only catch viruses indoors.
b high - humidity air causes common viruses.
c there is a direct connection between viruses and humidity.
d people can avoid viruses by spending more time outdoors.

Explanation:

• Option A: The text doesn't say people only catch viruses indoors. It just mentions viruses survive better in low - humidity indoor air.
• Option B: High - humidity air doesn't cause viruses. The text says viruses survive better in low - humidity.
• Option C: The text states that viruses survive better in low - humidity indoor air. This shows a connection between viruses (their survival) and humidity.
• Option D: There is no information in the text to support that spending more time outdoors will help avoid viruses. Just because viruses survive better indoors (in low - humidity) doesn't mean outdoors is a virus - free zone.

Answer:

C. There is a direct connection between viruses and humidity.
