### HideShow timer Statistics

The teeth of some mammals show growth rings that result from the constant depositing of layers of cementum as opaque bands in summer and translucent bands in winter. Cross sections of pigs teeth found in an excavated Stone Age trash pit revealed bands of remarkably constant width except that the band deposited last, which was invariably translucent, was only about half the normal width.

The statements above most strongly support the conclusion that the animals died

(A) in an unusually early winter

(B) at roughly the same age

(C) roughly in midwinter

(D) in a natural catastrophe

(E) from starvation

I'll go with C .

c)roughly in midwinter

Since the last band is translucent the pig should have died in winter .
And since the band is only about half the normal width.The animal should have died some where midway. through the winter.

I think only C is appealing.

Another C.

(A) in an unusually early winter (then the previous layer would be thinner too)

(B) at roughly the same age (the number of layers might have varied among pigs; argument doesn’t say otherwise)

(C) roughly in midwinter (good – the last layer was only half the normal width)

(D) in a natural catastrophe (could be, but still, we can conclude only about the time when the death came, not about the cause)

(E) from starvation (the same - we can conclude only about the time when the death came, not about the cause)
