Question

for the ancient egyptians, the nile river was an important natural resource, or environmental feature that people used to meet their needs. look at the diagram describing the flow of the nile river. then answer the question below.
the flow of the nile river
(some text in diagram boxes: e.g., “the nile begins to flood”, “april–may: the nile is at its lowest point. harvest begins”, “sept.–oct.: the nile is at its highest point”, “nov.–march: the nile recedes. planting begins”)
which statement describes the nile river in ancient egypt?
the nile river had a constant, unchanging flow.
the nile river was dry for most of the year.
the nile river flooded at regular times during the year.
the nile river was entirely unpredictable.

Explanation:

To solve this, we analyze the diagram:

• The "constant, unchanging flow" is wrong as the diagram shows different stages (flood, recede, etc.).
• "Dry for most of the year" is incorrect since the diagram shows the Nile has water (floods, recedes, not dry).
• "Flooded at regular times" matches: The diagram has stages like (approx) June - Aug (flood begins), Sept - Oct (highest), Nov - March (recedes), April - May (lowest), showing a regular annual cycle.
• "Entirely unpredictable" is wrong as the stages are regular (flood, recede, etc. at consistent times).

Answer:

The Nile River flooded at regular times during the year.
