Reading the passage
The third group thinks there was a distinct event, but one limited to the Earth-Moon system. Its short duration is the reason for that local explanation.
Working the answers
- A
“Only the Moon” leaves out Earth. This group places the breakup within the Earth-Moon system.
- BCorrect
The text explicitly connects the “relatively brief duration” with the claim that the catastrophe didn't extend throughout the inner solar system. Local debris would have been swept up quickly.
- C
The explanation concerns where the breakup occurred and how quickly its debris disappeared. It doesn't attribute the short duration to a small quantity absorbed by planets across the inner solar system.
- D
This group disputes the event's reach, not the four-billion-year date.
- E
The local extent fits, but “may have lasted a long time” does not. A brief event is central to this group's reasoning.
