Question

the lights are harmless to living things, but they can disrupt satellite communications and radio and television broadcasts. because the flow of charged particles and magnetism can damage electrical power grid and the satellites we depend on, scientists are studying solar storms and auroras so that they can better predict their occurrence. which conclusion does the paragraph support? radiation from solar storms poses a threat to people and other life forms on earth. scientists have little understanding of how auroras affect conditions on earth. some types of human technology are vulnerable to bursts of energy from the sun. solar energy from auroras is a resource that can power electronic devices on earth.

Explanation:

1. The first option is incorrect because the text states the lights (auroras) are harmless to living things.
2. The second option is incorrect; the text says scientists are studying solar storms and auroras to predict them, not that they have little understanding.
3. The third option is correct: the text notes that charged particles/magnetism from these solar events disrupt satellite communications, radio/TV broadcasts, and can damage power grids and satellites—all human technologies vulnerable to solar energy bursts.
4. The fourth option is incorrect; the text does not mention using aurora energy as a power source.

Answer:

Some types of human technology are vulnerable to bursts of energy from the sun.
