Key steps

• uncertain = not certain; the prefix un- gives the opposite meaning.
• historians are people who study history.
• valuable is an adjective describing food crop.
• undoubtedly is an adverb meaning “without doubt”.
• After for, we need a noun: survival.

In the first sentence of III, use the pattern:

About 3 billion people undoubtedly depend on it for survival. The importance of rice is reflected worldwide in many myths and legends. One Chinese legend tells of a certain time when a destructive flood damaged all the crops. One day, hungry people saw a dog with unusual yellow seeds on its tail.
