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.

Which one of the following is most supported by Dr. Khan's statements?
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.
Contrary to Professor Burns's view, the recent observations confirm the earlier ones.
Professor Burns's claim about the implications of the recent observations is incorrect.
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.
The poor conditions present during recent observations render them worthless.
