How is the information on the "Volcanoes" page organized?

The page in question is the information on the Volcanoes from  ready.gov

The answer to the question is B. The page presents four different kinds of threats that volcanoes pose and what to do before, during, and after an eruption.

When looking at the page we can see it is separated as the manual for the volcano eruption. It first lists the hazards of the volcano eruption, what to do if the warning starts, and then explains how to act now, during and after the eruption.

There is no information about scientific researches, dangerous volcanos or shelters.

this would be in the imperative mood. it is a category of verb forms that are used to express orders,instructions,commands or requests.
