Reading the passage
Why did the mammals survive? They were small. The final paragraph directly connects smaller size with being better able to survive the catastrophic climate changes. The author then explains why having that useful size was a matter of luck rather than preparation for the impact.
Working the answers
- A
They couldn't have adapted in advance to the new conditions, according to the author. Nothing says they had survived similar changes before.
- BCorrect
The final paragraph explicitly says smaller species were better able to survive, and the mammals in question were small.
- C
Intelligence isn't offered as an explanation.
- D
We aren't told these mammals occupied a wide range of environments. That might sound like a useful survival advantage, but it isn't the reason given here.
- E
Rapid reproduction isn't mentioned either. A plausible biological explanation is not a substitute for the one the question asks us to identify.
