Dr. Khan: Professor Burns recognizes that recent observations fail to confirm earlier ones that apparently showed a comet reservoir far out in our solar system. She claims this nonconfirmation is enough to show that the earlier observations are incorrect. But the recent observations occurred under poor conditions.

Summary

Recent observations fail to confirm earlier observations that showed a comet reservoir far out in the solar system, according to Professor Burns. Professor Burns claims that this failure to confirm is enough to show that the earlier observations are incorrect. The recent observations occurred in poor conditions.

Strongly Supported Conclusions

The recent observations are not sufficient evidence to show that the earlier observations are incorrect.

A
If the recent observations had been made under good conditions, they would have provided conclusive evidence of a comet reservoir far out in our solar system.

This is anti-supported because even if the recent observations were accurate, those observations failed to confirm earlier observations about a comet reservoir in the solar system.

B
Contrary to Professor Burns’s view, the recent observations confirm the earlier ones.

This is anti-supported because the recent observations were taken when weather conditions were poor, meaning they are probably not useful results. This means they shouldn’t be used to confirm any findings one way or another.

C
Professor Burns’s claim about the implications of the recent observations is incorrect.

This is strongly supported because the author states that the recent observations were taken when weather conditions were poor, which casts doubt on their validity. Since Professor Burns uses these observations to cast doubt on earlier observations, Professor Burns is incorrect.

D
The recent observations, even if they had been made under good conditions, would not have been enough to suggest that the earlier ones are incorrect.

This is unsupported because the author doesn’t explore how we should have interpreted the results of recent observations if those observations had been made under good conditions.

E
The poor conditions present during recent observations render them worthless.

This is unsupported because while the poor conditions cast doubt on recent observations’ usefulness in evaluating the earlier observations, it is too strong to say that the poor conditions makes them entirely worthless.
