read the paragraph. then, add the best topic sentence. one sign of a storm is a change in air pressure, the weight of the air pressing down on the earth. dogs can sense this change, so they may act nervous before a storm. birds may also fly lower, and frogs may croak more. even insects notice differences in the air before a storm. sensing that the air has more water in it, flies and mosquitoes come out before a storm. weather and noise levels can change the ways animals behave. some animals act differently before an earthquake hits. certain animals act differently right before a storm hits. some dogs get frightened before a storm.
Answer
# Brief Explanations:
The paragraph details how various animals (dogs, birds, frogs, flies, mosquitoes) act differently before a storm due to air - pressure and moisture changes. The best topic sentence should summarize this. The first option is too broad with "weather and noise levels", the second is about earthquakes not storms, and the fourth is only about dogs. The third option, "Certain animals act differently right before a storm hits", best captures the main idea of the paragraph.
# Answer:
Certain animals act differently right before a storm hits.
