Official Explanation

The question asks for a possible characteristic of a group and a prediction about the group such that knowledge that the group has the characteristic would support the prediction. The question suggests that the answers for the two response opportunities may be dependent, such that the correctness of the answer for one response opportunity depends on the correctness of the answer for the other.

The evidence from the archeologist might support a prediction that the group uses thin-walled pots, on the basis of the group’s being sedentary rather than nomadic. The evidence might also support the prediction that the group is nomadic rather than sedentary, on the basis of its using thin-walled pots. However, the archaeologist states that a prediction can be made about pottery use. The archaeologist thus most strongly suggests that usage of thin-walled pots by a group can be predicted on the basis of the group’s being sedentary rather than nomadic.

The correct answer are The group is sedentary rather than nomadic and The group uses thin-walled pots.

Can someone explain with the Prediction that they use thin-walled pots, why can't the characteristic be uses fire for warmth and protection?

The advantage of thin-walled pots, as given in the passage is that thin-walled pottery is better able to resist the damaging effects of thermal stress resulting from being placed over a fire.

If someone uses fire for warmth and protection, can we say that he/she is placing pottery over fire?

I don't think so.

If this option had been "The group uses pottery to heat food over fire", it would have been correct. Of course, then we'll not have the first option since we cannot have two answers.

God, I always get the answers reversed on these types of questions. Any way to avoid repeating the mistakes?

Thanks - I had a simialr doubt and understood.

But can you please explain why the characteristic is- "The group is sedentary rather than nomadic." I'm unable to understand this.­

Why is the vice-versa not the correct answer?

Focus on this sentence :- We can therefore make predictions about pottery use by a group of people on the basis of a certain lifestyle characteristic of the group.
What prediction can we make based on the passage :- about the pottery use   (  Note this part in the passage " We can therefore make predictions about pottery use by a group of people" ) . We can infer whether they are using thin walled or thick walled pottery.
GMATinsight . Hence , the group uses the thin walled pots "  is the prediction.

The basis is of this prediction is the lifestyle as mentioned in the passage ..."....on the basis of a certain lifestyle characteristic of the group".
Hence , "the group is sedentary rather than nomadic "  ===> is the characteristic.
Hope it helps. Quite simple stuff.

Note :- Sedentary is a lifestyle. Most IT professionals have sedentary lifestyle where as most army people have active lifestyle.

Re: Archaeologist: Although thin-walled pottery is better able to resist [#permalink]
Let's identify the correct characteristic and prediction:

1. Characteristic: This should describe the lifestyle of the group.
2. Prediction: This should describe the type of pottery they are likely to use based on their lifestyle.

==> Given this information:

1. Characteristic: The group is sedentary rather than nomadic.
A sedentary group is less likely to transport pottery frequently, so they are more likely to use thin-walled pottery, which is better at resisting thermal stress but prone to breaking during transport.

2. Prediction: The group uses thin-walled pots.
If a group is sedentary, they are more likely to use thin-walled pots due to the reduced risk of breaking during transport and the benefit of better resistance to thermal stress.­

---
Why not the reverse:

Logical Flow: The original statement logically flows from lifestyle to pottery use. It's easier and more straightforward to predict the type of pottery based on known lifestyle characteristics than to infer lifestyle solely from pottery type. A sedentary lifestyle (cause) leading to the use of thin-walled pots (effect) is a direct application of the archaeologist's reasoning.

Additional Factors: The use of thin-walled pots alone might not conclusively indicate a sedentary lifestyle since there could be other reasons for using thin-walled pots (e.g., cultural preferences, availability of materials). Predicting the pottery type based on lifestyle is more direct and accounts for the primary reason stated in the argument (resistance to thermal stress vs. transportability).
