Question

order the topics from broadest to narrowest.
broader
the nile rivers history of flooding
the history of the nile river
the nile river
the worlds longest rivers
narrower

Explanation:

To order the topics from broadest to narrowest, we analyze the scope of each:

1. "the world's longest rivers" is the broadest as it encompasses multiple rivers globally.
2. "the Nile River" is narrower than the previous, focusing on one specific river.
3. "the history of the Nile River" is more narrow, focusing on the history of that one river.
4. "the Nile river's history of flooding" is the narrowest, focusing on a specific aspect (flooding history) of the Nile's history.

So the order from broadest to narrowest is: the world's longest rivers, the Nile River, the history of the Nile River, the Nile river's history of flooding.

Answer:

1. the world's longest rivers
2. the Nile River
3. the history of the Nile River
4. the Nile river's history of flooding
