We're presented with two hypotheses about the charred bone deposits:
Hypothesis 1: They're the remnants of communal food preparation.
Hypothesis 2: They're the remains of ritual animal sacrifices where animals were burned whole during religious ceremonies.
We need to go through each option and find out which one gives us a definitive answer of the correct hypothesis while disregarding the other hypothesis in its entirety.
A. Whether similar deposits of charred animal bones have been found at other settlements in the same region.
This has nothing to do with the settlement in question and other settlements could follow entirely different practises, making this option
irrelevant.
B. Whether the bones belong to animal species that were commonly hunted for food in the surrounding region.
This still doesn't reject either hypothesis since the settlers could have possibly used the same animals that they considered food to be fit for sacrifice. Hence,
eliminated.
C. Whether the bones display cut marks of the kind produced when animals are butchered for the removal of meat.
This seems like a worthy option since the presence of cut marks would prove hypothesis 1 where the animal would be cut up for meat preparations and reject hypothesis 2 since the animals were sacrificed whole and would not have any cut marks on their bones. And in the absence of cut marks, it would prove hypothesis 2 and reject hypothesis 1.
Keep.
D. Whether the deposit contains bones from animals of various ages or predominantly from animals in their prime.
This is too vague since it can be applied to prove either hypothesis since the settlers could choose to sacrifice the animals in their prime and eat the ones of various ages, or the other way round, and hence it doesn't outright reject either hypothesis so it can be
eliminated.
E. Whether written or artistic records from contemporary cultures depict animals being used in religious ceremonies.
Again, this is too vague since there are a lot of contemporary cultures who could each follow their own distinct sets of rules and hence we cannot reject either of the hypotheses for this particular settlement with this option.
Eliminate.
Therefore, our
best option is C.
