Passage: 'Glacial retreat in high-mountain ecosystems disrupts seasonal hydrological cycles. Because snowpack and glacial ice act as natural reservoirs, their depletion leads to higher spring runoff accompanied by acute late-summer droughts, destabilising downstream agricultural economies.'
According to the passage, what is the primary consequence of glacial retreat during late summer?
Answer and explanation
Correct answer: D. Substantial water deficits affecting downstream farming
- Step 1: Scan the passage for the specific seasonal hydrological impacts occurring in late summer.
- Step 2: The text states that the loss of glacial ice reservoirs causes "acute late-summer droughts, destabilising downstream agricultural economies," which directly translates to substantial water shortages for downstream farming.
Answer
Substantial water deficits affecting downstream farming.
