Question Stats:

55% (01:32) correct

45% (01:35) wrong

based on 2 sessions

Anne: Halley’s Comet, now in a part of its orbit relatively far from the Sun, recently flared brightly enough to be seen by telescope. No comet has ever been observed to flare so far from the Sun before, so such a flare must be highly unusual.
Sue: Nonsense. Usually no one bothers to try to observe comets when they are so far from the Sun. This flare was observed only because an observatory was tracking Halley’s Comet very carefully.

Sue challenges Anne’s reasoning by

a) pointing out that Anne’s use of the term “observed” is excessively vague
b) drawing attention to an inconsistency between two of Anne’s claims
c) presenting evidence that directly contradicts Anne’s evidence
d) offering an alternative explanation for the evidence Anne cites
e) undermining some of Anne’s evidence while agreeing with her conclusion

Sue challenges Anne’s reasoning by

a) pointing out that Anne’s use of the term “observed” is excessively vague no where has this been done!
b) drawing attention to an inconsistency between two of Anne’s claims Sue doesn't mention anything about consistency of Anne's claims
c) presenting evidence that directly contradicts Anne’s evidence Sue does not present any evidence
d) offering an alternative explanation for the evidence Anne cites Correct answer. Sue provides alternate explanation using the same evidences that Anne states
e) undermining some of Anne’s evidence while agreeing with her conclusionWrong, infact sue contradicts the conclusion

Hope this helps

Hi,
For option B, you have said that Sue doesn't mention anything about the consistency of Anne's claims.
However, she does point out to the inconsistency, doesn't she?
Sue says, that the fact that Halle's comet was observed to have flared was because it was being tracked (ie specifically observed).
