Passage Summary: Most people think space rocks hit Earth at random, but one scientist thinks there is a pattern because of a specific ring of craters found in the north from the time the dinosaurs went extinct.

Conclusion: Asteroid impacts on Earth are the result of a highly organized natural process rather than random occurrences.

Reasoning: There is a specific, non-random pattern of craters in the Northern Hemisphere that all date back to the same geological time period.

Analysis: The geophysicist is trying to prove a highly organized process based on a single pattern of craters. To strengthen this, we need to bolster the link between that specific pattern and the idea of a non-random, organized system. Look for an answer that suggests this pattern could not have happened by chance or provides additional examples of non-random impact clusters. We want to move the needle from 'this looks like a pattern' to 'this must be a pattern,' perhaps by showing that the timing of these impacts is too precise to be a coincidence.
