Question

giant planet migration likely occurred much earlier, around 4.48 billion years ago, shortly after the planets formed. based on the texts, how would mojzsis and brassers (text 2) most likely respond to the theory discussed in text 1? choose 1 answer: a by arguing that the great planet migration was not actually caused by a gravitational instability b by disputing the idea that the great planets initially formed closer together than their current positions c by claiming that the great planet migration occurred earlier than the theory proposes d by asserting that the lunar rock evidence and cratering record of the inner solar system are not reliable sources of evidence

Explanation:

The key point is to analyze the time - related claim. Text 2 states the migration was around 4.48 billion years ago (shortly after planet formation), while we assume Text 1's theory has a different time frame. Mozjsis and Brassers would likely focus on the time aspect.

• Option A: There is no indication in the given text about the cause (gravitational instability) being disputed.
• Option B: There is no mention of the initial formation distance in the given text for a dispute.
• Option C: Since Text 2 gives an earlier time (4.48 billion years ago) for the migration, if Text 1's theory has a later time, this option is correct.
• Option D: There is no information about disputing the evidence sources (lunar rock and cratering record) in the given text.

Answer:

C. By claiming that the great planet migration occurred earlier than the theory proposes
