Hi Cherisse,
Thanks for the update and for letting us know where these come from.
Overall I think that these questions are not necessarily a good representation of the type of questions you can expect on the current PMP exam. These seem more like knowledge-based questions that are intended to test your understanding of the materials from within a training course. The PMP exam contains more situational questions where you have to analyze what's going on and then make a decision based on the event that is happening.
That much said I agree with the answers you have chosen. Questions #2 and #3 could go either way and you can make an argument for the other answer choices. But I think you picked the right one. And question #5 is so oddly phrased that it's really hard to understand. Again, I would not expect to see something like this on the exam, but your answer also seems to be correct.
