Passage Summary: The author argues that spending money to study asteroids is a smart move, comparing it to how regular people buy house insurance to prepare for 'what if' scenarios.

Conclusion: Government funding of Near-Earth Object (NEO) research is a justifiable and wise expenditure.

Reasoning: Just as individuals buy home insurance to protect against potential disasters, governments fund NEO research to prepare for the possibility of an asteroid collision.

Analysis: The statement about home insurance serves as an analogy intended to support the main conclusion. By comparing asteroid research to a common, sensible financial practice like insurance, the author attempts to show that the government's spending is rational rather than wasteful. In 'Role in Argument' questions, focus on how this comparison functions as a premise that establishes a general principle of fiscal prudence. It provides a familiar context to help the reader accept the author's stance on a more abstract scientific topic.
