3. C Interpret stem: Weaken
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
Conclusion: This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language
General Prediction: “I need a reason that Neanderthals could NOT have made their amazing tools without language.
In other words, they needed language.Interpret: what is language needed for? To collaborate with one another. To strengthen this “I need a reason that the N’s needed to collaborate with each other or others/other groups.”
Premises:
• Experiment—college students taught to make A tool
• They did it fine even in the group that did not use a verbal language to communicate.
Notice any WEAKNESSES in the argument:
FLAW! OVERGENARALIZATION. It generalized from Neanderthals to a modern group of students!
Specific Prediction/Considering the argument in its whole.
Maybe the students are just not the same as Neanderthals… the experiment has a FLAW! It generalized from Neanderthals to a modern group of students. Maybe the students could do it without language but the
Neanderthals may not have understood the techniques needed. The N’s may have needed more instruction than our students did. Maybe the N’s learned from a visiting tribe… all of that could mean they could need some type of verbal communication.A couple of points here:
• Specific predictions are not as helpful as general ones—they take longer to think of, they may not match the answers given, and as a comparison, the general prediction works BETTER!
• This is a clear example of a harder question. 700-level questions need PRACTICE, PRACTICE, PRACTICE so that your creative, problem-solving mind is stimulated and experienced. A young solver who is just starting to look at GMAT/LSAT problems would likely have a very difficult time with this question
• KEEP PRACTICING!
• On test day, you would have gone to the answers almost immediately after the general prediction.
• There ARE
HINTS in the passage--specific words--the students made one of many types of tools the N's made-- These hints help you to connect harder questions. Problem? It takes a lot of PRACTICE to learn to see these.
• KEEP PRACTICING!
A. Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
So??? This doesn’t mean they needed it to make their tools.
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.
SOOO? No better than A at connecting to the conclusion.
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. Hmmmm. I wasn’t sure at first. This seems to need a bit of interpretation. I’ll come back. I think it MAY be our answer. I’ll check and see if D and E have errors.
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.
SOOOOOO??? What does this tell us about what the N’s needed??
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.
Ewww. I am going to interpret C first. At first glance, I don’t think this connects me to the conclusion, and furthermore, I think it might be the OPPOSITE of what we want to do. Let’s do C.
C. As I consider, this simply says that IF a harder tool was made by the N’s, (see the specific words…) this MIGHT indeed be the reason that the N’s needed to collaborate, discuss ideas, communicate, learn from one another’s experience etc. This weakens the ability to get to the conclusion b/c it makes the experiment NOT valid. It makes the experiment an even bigger over generalization. This gives us the info we need to FAIL to get to the conclusion.
Done. Weakened!
