Ok you can use POE

1. The passage does not mention anything about the fact that Paczynski's theory is no longer credited. Out of Scope

2. Again there is no criticism mentioned against Paczynski or any other astronomers theory. Out of Scope.

3. The author does discuss the reason why Pacynski proposed the MACHO theory, but the passage does not discuss whether the theory was influential or whether any one got influenced by it. The 2nd part is Out of Scope.

4. No dispute between the astronomers is mentioned. Irrelevant.

5. The author first explains Paczynski's theory. Then he says that the microlensing logic can be flawed and he goes on to explain why it could be incorrect. Notice this line in the passage, 'can be mistaken for microlensing'. The portion after this line, the author explains why the astronomers can mistaken the phenomenon as microlensing. (Its in the 10th last line).

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
