Read and understand · 1/2What interval do the images cover?

Read the answer and explanation

September 20 to November 7. The first paragraph supplies the two image dates.

Clue: NASA’s November 11 account compares Landsat 9 images of Navajo Reservoir from September 20 and November 7. Water levels rose nearly 18 metres over that interval.

Read and understand · 2/2Why does fuller storage not prove every drought problem ended?

Read the answer and explanation

Long-term drought persisted in places. The final paragraph explicitly says long-term drought persisted.

Clue: The storms eased short-term drought while causing destructive river floods. Long-term drought persisted in places, so fuller water storage was not evidence that every drought problem had ended.

Grammar in this story: Simultaneous contrasting effects

while causing

While connects drought relief with flood damage happening during the same storms.

Your turn

Explain why the recovery needs qualification.

See one possible answer

The reservoir rose rapidly, but the storms also caused destructive floods and long-term drought remained in some places. Fuller storage therefore does not prove that every drought problem ended.

Your answer can be different. Give a reason and use your own words.
