Anthropologist: In an experiment, two groups of undergraduates were taught how to create one of the types of stone tools that the Neanderthals made in prehistoric times. One group was taught using both demonstrations and elaborate verbal explanations, whereas the other group learned by silent example alone. The two groups showed a significant difference neither in the speed with which they acquired the toolmaking skills nor in the level of proficiency they reached. This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language

Which one of the following, if true, most weakens the anthropologist's argument?

(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.

(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.

(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.

(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.

(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.

I find C a better answer. It is completely unclear that why E is right. Can someone please explain.

Conclusion: Neanderthals could have produced their sophisticaed tools even if they did not possess language.
Premise: As two groups of students, one using language and the other not, were both able to produce one of the types of tools used by Neanderthals.

Prethinking : Argument that can highlight the difference in tool made by 2 groups of student and Neanderthals will weaken the Conclusion

(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
out of scope. The argument is about whether there is relation between Sophistication of the tools produced by Neanderthals and their language skill. This option is about whether there is other evidence that Neanderthals possessed language.

(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.
This option strenghtens the argument as other group without any verbal explanation and discussion among themselves was able to make the tools at same proficiency as first group

(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.
correct choice. As this option would make the comparision to undergraduate students less relevant since the tools made by the undergraduate students were less sophisticated than those made by the Neanderthals

(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.
out of scope, As we are discussing the relation between langauge skills and ability of Neanderthals to make sophisticated tools

(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.
out of scope. The question isn't whether the tools produced by Neanderthals were more (or less) sophisticated than those produced by anatomically modern humans, but whether the tools produced by Neanderthals are evidences that they possessed language.

OA should be C

In the question stem
Conclusion- Neanderthal have made tools in same way even if they don't have language

It uses results of experiment to reach conclusion.
But we can show that tools designed by Neanderthal are different from created during experiment we can weaken argument.

C and E r possible candidate

But E is wrong because if Neanderthal tools are much less sophisticated thenthe reasoning in argument somewhat support the conclusion.

Whereas C clearly states weakness in argument
