Question

How does the author's inclusion of the bar graph comparing rainfall and drought across time periods in "Marvelous Moisture" contribute to the author's purpose?

It is meant to entertain readers by summarizing facts through pictures instead of words.

It provides a timeline of historical events that are unrelated to the author’s central idea about rainfall.

It distracts from the author’s argument by focusing too much on ancient Egypt and not modern times.

It visually shows how rainfall has helped and harmed human life, supporting the author’s point that water shapes civilization.

Answer 1

It’s the last option. The bar graph visually demonstrates how periods of rainfall and drought affected societies over time, supporting the author’s claim that water both helps and harms human life and thus shapes civilizations.
