I was wondering if someone could check my work on this one.
This is a method question. We are looking for an answer choice that describes the reasoning the author used to arrive at the conclusion.
Conclusion is that any serious amateur should choose the E (exodus) if they are buying telescope for observations.
WHY: Some observers tested out the E and they saw observations in crisp detail, even though the other telescope gives off more light and is longer.
Speaking in abstract terms, the author argues for one method over an alternative by showing that the first was better in some way for something than the alternative.
a. Which claims?
b. They are testing the telescope, but the author is not showing how the testing is similar to ordinary use, but instead how the testing shows that it's good for ordinary use.
c. No, it's arguing for a wider usage of the phenomenon.
d. This is the interesting choice. I had a hard time identifying the group from the subset, as the stimulus talks about interested amateur astronomers in both instances. It seems though that the group is all amateur astronomers and the subset is the experience of the amateur astronomers when testing the E telescope, and the argument makes a conclusion about first on the basis of information about the second.
e. Might also be tempting, but the argument does not distinguish between the two.
Is my reasoning right for D?
Thanks.
