Question

Explanation

Show analysis

Support 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. █████ ████████ ██ ███████ █████ █████ ██ ██ █████████ █████ ███ █████ ███ ████████ █████ ██ ██████████ ████████ █████ ██████ ████ ███ ████ █████████ █████ █████ ███ ██████████ ████████████ ███ ████ █████ ████ ███ ██████ ██████

Argument Structure

This stimulus starts by giving us general information about growth rings in some mammals' teeth. These are formed by opaque bands of cementum deposited in the summer and translucent ones deposited in the winter. Then the stimulus tells us about the specific case of pigs' teeth found in a Stone Age trash pit. These all had cementum bands of constant width except the last one, which was translucent and half the normal width. The stimulus doesn't draw a conclusion from these statements.

Notable Inferences

The stimulus presents us with a general claim about how these growth rings are formed, and then tells us about a specific scenario with an unusual aspect: the final growth ring on the pigs' teeth was half the width of the others. From the first sentence, we know that translucent cementum bands are deposited in the winter. So the fact that the last band was "invariably" translucent might suggest that these pigs died sometime in the winter.

in an unusually █████ ██████

This is a tricky answer choice. The narrower width of the last band might suggest the pigs died "early", in some sense, and the fact that the band was translucent does suggest the pigs died after winter had begun. But we have no support for the claim that the winter itself arrived "unusually early." If anything, the fact that the opaque band just before the last band was apparently of the same width as the others might suggest that the winter actually arrived at the usual time. Even if this weren't true, we would have nothing in the stimulus to indicate when the winter had arrived, only that it did.

at roughly the ████ ███

This isn't supported. The information in the stimulus only tells us about general characteristics of the growth rings on each tooth. We aren't given a comparison of the growth rings on teeth from different pigs, so we can't say whether or not the pigs were the same age when they died. It's possible some of the pigs had many more growth rings on their teeth than others — the stimulus doesn't say.

roughly in midwinter

This is supported. The fact that the last band is translucent suggests the pigs died in the winter, and the fact that it was half the width of the normal bands suggests that they died in the middle of winter, about halfway through the process of depositing translucent cementum.

in a natural ███████████

Nothing in the stimulus gives us any indication of the cause of the animals' death.

from starvation

Nothing in the stimulus gives us any indication of the cause of the animals' death.
