Question

be aware of mudflows. the danger from a mudflow increases near stream channels and with prolonged heavy rains. mudflows can move faster than you can walk or run. look upstream before crossing a bridge and do not cross the bridge if a mudflow is approaching. what is the main idea of this paragraph from the \volcanoes\ section of the ready.gov website?
a. the main cause of a mudflow
b. why mudflows happen near streams
c. what to do if you get caught in a mudflow
d. how to stay safe around a mudflow

Explanation:

• Option A: The paragraph doesn't focus on the cause of mudflows, but on safety around them. Eliminate A.
• Option B: The mention of streams is part of describing mudflow danger, not explaining why they happen near streams. Eliminate B.
• Option C: The paragraph gives advice on actions like looking upstream and not crossing a bridge when a mudflow is approaching, not what to do if caught in one. Eliminate C.
• Option D: The paragraph provides warnings (danger near streams, speed) and actions (look upstream, don't cross bridge if approaching) to stay safe around mudflows. This matches.

Answer:

D. How to stay safe around a mudflow
