Archaeologists excavating an early agrarian settlement discovered a concentrated deposit of charred animal bones at the center of the site.
The bones represent several different species and show varying degrees of burning.
Hypothesis 1: The deposits may be the remnants of communal food preparation - animals slaughtered and cooked during larger gathering of the settlement's inhabitants.
Hypothesis 2: The deposits may represent the remains of ritual animal sacrifices, in which animals were burned whole as offerings during religious ceremonies.
Useful to evaluate the argument:
Pre-thinking: If cut marks are present, then animals might have been used in food preparation and if they are not present, the animals might have been burned whole during ritual sacrifices.
A. Clarifies how common the practices were in the region but don't help in ascertaining for which purpose animals were used (food vs sacrifices) at the specific site.
Incorrect
B. Animal species that were commonly hunted for food could have been used for ritual sacrifices as well. Even if it is established that bones belonged to animal species that were commonly hunted for food, it does not clarify the purpose (food vs sacrifice) the animals were used for.
Incorrect
C. If bones display cut marks of the kind when animals are butchered for removal of meat, then they were used for food preparation. If not, then they were probably used for ritual sacrifices. This matching our pre-thinking.
Correct
D. Age of animals can not help us in finding their usage (food vs sacrifice). Animals of various ages could have been used for both purposes.
Incorrect
E. Records of contemporary cultures depicting animals being used for religious ceremonies don't rule out their usage for food preparation at the specific site and don't help us in finding their usage (food vs sacrifice)
IMO C
