Answer:
Convection current
Explanation:
Convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air, the cold air due to its greater density moves downward, and the cycle continues, this upward and downward movement is called convection current.

The author most likely includes this supporting text to <em><u>reinforce the case study's point that bird flu is dangerous</u></em>.
Explanation:
The book "When Birds Get Flu" by John DiConsiglio delves into real cases of how people contract the bird flu. The book discusses infection cases and how avian influenza or bird flu began in Washington.
In the statement from the book, the author remarks that <em>"one or two sick chickens could infect a whole town [which could in turn] infect the country—or even the world."</em> By emphasizing the seriousness and infection level of the flu, <u>John DiConsiglio seems to reinforce the dangerousness of the bird flu.</u>
Thus, the correct answer is the first option.
