Question

story 3: the storys main idea is that unusually strong solar storms produced rare and widespread sightings of the northern lights across the united states. which detail most strongly supports this idea?
some people enjoy photographing the night sky when conditions are clear.
the geomagnetic activity also disrupted communication satellites and delayed a nasa mission.
the moon appears brighter in certain phases.
national parks often provide good locations for stargazing

Explanation:

To determine the detail that supports the main idea (strong solar storms caused rare northern lights sightings), we analyze each option:

• The first option is about night - sky photography, which has no relation to solar storms or northern lights.
• The second option states that geomagnetic activity (caused by solar storms) disrupted satellites and a NASA mission. Since solar storms are the cause of both the northern lights and this geomagnetic - related disruption, this option supports the idea that strong solar storms had significant effects (including enabling northern lights sightings).
• The third option is about the moon's phases, which is irrelevant to solar storms and northern lights.
• The fourth option is about stargazing locations in national parks, which doesn't relate to solar storms or northern lights.

Answer:

B. The geomagnetic activity also disrupted communication satellites and delayed a NASA mission.
