Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. energy.
- The passage is about how glacial meltwaters are used to generate hydropower. It mentions that reservoirs filled by meltwaters help supply the nation's needs.
- "Energy" is a more general term that encompasses all types of energy produced, including electricity. It is suitable here as it aligns with the broader context of energy supply, which includes electricity.
- Thus, the completed sentence is: "So one consequence is that melting glaciers help to compensate for low rainfall in times of drought, filling reservoirs to supply the nation's energy supply."
- This sentence correctly indicates that the water from the melting glaciers helps ensure a steady supply of energy, addressing potential shortages during drought periods.
