Question

1. which sentence from the passage supports the idea that sunspots cause more auroral light?

\however, sometimes the lights can be seen outside their usual latitudes, usually during high sunspot activity.\
\this causes more charged particles to be ejected from the sun...\
\because sunspot activity is cyclical, auroral light displays tend to be cyclical as well.\
\the lights are harmless to living things, but they can disrupt satellite communications and radio and television broadcasts.\

Explanation:

To determine which sentence supports sunspots causing more auroral light, we analyze each option:

• First option: Talks about lights being seen outside usual regions during high sunspot activity, but doesn't directly link sunspots to causing more auroral light.
• Second option: "This causes more charged particles to be ejected from the sun..." - If sunspots lead to more charged particles (which cause auroral light), this shows the causal link.
• Third option: Discusses the cyclical nature of both, not causation of more auroral light.
• Fourth option: Talks about effects of auroral lights, not what causes more of them.

The second option explains that sunspot - related activity (implied by "this") causes more charged particles, which are responsible for auroral light, so it supports the idea.

Answer:

The option with the sentence "This causes more charged particles to be ejected from the sun..." (the second option among the given choices)
