LR Question 2 Explanation

QUESTION TEXT: The teeth of some mammals show “growth rings” that result…

QUESTION TYPE: Most Strongly Supported

ANALYSIS: Cementum is deposited in opaque bands in summer and translucent bands in winter. The bands are always the same size.

Since the final band was translucent we can say it was deposited in winter. Since it was half the normal size it is likely the pigs died halfway through winter.

___________

1. We have no evidence the winter was early. We have evidence the pigs died before winter was over, that is all.
2. We don’t know how many bands the pigs had each, some may have been older. We only know they died at roughly the same time, after they had each deposited half of a translucent band that winter.
3. CORRECT. Yes. Translucent bands are placed in winter. And since the bands are half of the normal size, we can guess that the pigs died halfway through winter.
4. We have no evidence of how the pigs died, only when.
5. Same as D.
