Archaeologists excavating a Neanderthal campsite found discarded gazelle teeth there whose coloration indicated that gazelles had been hunted throughout the year. The archaeologists concluded that the Neanderthals had inhabited the campsite year-round and thus were not nomadic. In contrast, the archaeologists cite a neighboring campsite of nomadic Cro-Magnons that contained teeth from gazelles all killed during the same season.
Which one of the following, if true, most seriously weakens the archaeologists’ reasoning?
(A) Neanderthals hunted a wide variety of both migratory and nonmigratory animals.
(B) Cro-Magnons and Neanderthals sometimes exchanged tools.
(C) Neanderthals saved gazelle teeth for use in religious rituals and later discarded them.
(D) Cro-Magnons usually followed the migrations of the animals they hunted.
(E) Gazelles inhabited the area around the campsites year-round.

Premise
At the Neanderthal campsite, discarded gazelle teeth suggest gazelles were hunted throughout the year.
Cro-Magnons show gazelle teeth from only one season, and they were nomadic.
Conclusion
Neanderthals lived at the campsite year-round, so they were not nomadic.
Prethinking
The argument assumes that year-round evidence of hunting means year-round residence.
To weaken this, we need another explanation for the mixed-season teeth that does not require year-round living.
Option check
A Different animals hunted → irrelevant to residence timing
B Tool exchange → unrelated
C Teeth were saved and later discarded → could mix seasons even if hunting was not year-round
D Cro-Magnons follow migrations → supports comparison but does not weaken Neanderthals
E Gazelles lived year-round → strengthens the argument
Correct Answer C
Conclusion
C is correct because teeth could have been accumulated over time and dumped later, so it does not prove Neanderthals lived there year-round.

In contrast, the archaeologists cite a neighboring campsite of nomadic Cro-Magnons that contained teeth from gazelles all killed during the same season.
Which one of the following, if true, most seriously weakens the archaeologists’ reasoning?
The archaeologists assume that the gazelle teeth found at the campsite were discarded there soon after the gazelles were hunted. The key weakness is that the teeth may have been collected elsewhere or over time and then discarded at the campsite later. If so, year-round gazelle teeth do not prove year-round habitation.
(A) Neanderthals hunted a wide variety of both migratory and nonmigratory animals.
Wrong. This does not explain why gazelle teeth from all seasons were found at the campsite.
(B) Cro-Magnons and Neanderthals sometimes exchanged tools.
Wrong. Tool exchange does not affect whether the gazelle teeth prove year-round habitation.
(C) Neanderthals saved gazelle teeth for use in religious rituals and later discarded them.
Correct. If Neanderthals saved the teeth and discarded them later, then the campsite could contain teeth from gazelles killed in different seasons even if the Neanderthals did not live there year-round.
(D) Cro-Magnons usually followed the migrations of the animals they hunted.
Wrong. This supports the idea that Cro-Magnons were nomadic, but it does not weaken the conclusion about Neanderthals.
(E) Gazelles inhabited the area around the campsites year-round.
Wrong. This may explain how gazelles could be hunted there year-round, but it does not weaken the claim that Neanderthals stayed there year-round.

Correct. If Neanderthals saved the teeth and discarded them later, then the campsite could contain teeth from gazelles killed in different seasons even if the Neanderthals did not live there year-round.
