Hi Elva,
Sorry to rain on your parade a little but you're unlikely to find textbook answers to all of those questions...and i'm not going to provide them for you. But here's a few tips on answering questions in physio:
It's all about developing your clinical reasoning and your logical thought processes. So basically head off to your favourite anatomy text and look carefully at the muscles, ligaments etc around the pelvis and the structures you're being asked about. (and one of the best lessons a lecturer ever taught me way back in the day was to know your anatomy). Then find out what the actions of those muscles are and which actions they oppose. And then it's up to you to use your logic and mental gymnastics to extrapolate what would happen if the muscles were too weak/strong/tight/long etc.
Essentially the questions aren't asking you to find the perfect answers from a book and re-hash them to your lecturers, ...it's asking you to use your logic and reasoning to apply your anatomical knowledge, and biomechanics to justify your answers. So you should be able to find out the basics like the anatomy and biomechanics (your levers and pivots/fulcrums) and then apply that to answer the questions.
Good luck.
