There have been many posts in the past where people have attempted to get us to do their course work for them and the usual reply, as in your case is, do your research to the point at which you feel confident about your answers. 

Perhaps John and I should set up in business doing people's course work for them, then we might make a bit of extra money on the side.

Do you feel much better now by writing this message? Yes I woke up one morning and I thought that it would be an perfect idea to get people to do my course instead of me, yes I'm so lazy that I'm looking for someone to do the job instead of me. My geology book is not yet available in my schools library, I've even tried to loan some other book that would might help me, witthout any success, so I've spent many days by searching for information on google, and by that I failed to get an A, so writing here was my last option. Goosh I just hate people like you -.-

Go back to your lecturer and explain the situation to them about your books etc.  But to be honest, even if I was sympathetic to your problem I'm not inclined to cooperate now as you clearly think it's ok to throw a tantrum if you don't get your own way.

Fully agree.  One day you will thank Gus for saying that.  In the real world you have to think for yourself, and not get stroppy and childish because you are told a few home truths.

I just Googled 'Evidence for sea floor spreading' and came up with no end of hits. But within the third one are complete answers (not just multi choice) to your first question, so your 'having searched for days' doesn't actually add up. It took me minutes.

We are more than willing to help with the odd questions YOU might have, or even discuss various topics. 

So the first question you should be asking your tutor is why is the reference book for this not available in the library?

You don't say where you are, or what level you are working at, but, assuming you are English and doing A level geology, the recommended book for that was McLeash 'Geological Science'  ISBN 0-17-448221-3. Published by Nelson Press and available through Blackwells in nowhere else.  Its not an expensive book, and obviously I still have my copy - I certainly didn't remember that information.

While I agree with Gus and John that this site should not be a homework answer site, some extenuating circumstances exist to explain your thwarted reaction that compel me to offer some opinions and partial answers. On question 1, I doubt that heat flow is a reliable or even  available measure of seafloor spreading since there is considerable ongoing controversy over how to locate magma pools by seismic tomography or other methods. Seafloor bathymetry seems a more promising means for locating midocean spreading ridges. I don't know how anyone can answer the question on pole wander from the cited tellus test 1 figure which shows animated landmass wanderings from 560 to 30 Mya in 10 Ma increments. This animation is the best thing I've ever seen on this topic which even beats www.scotese.com if it is accurate. It shows India docking with Eurasia around 30 Mya while some claim this happened as long as 65 Mya. Others say it was a 2 phase docking so 30 Mya is not implausible for the 2nd phase. On the plate subduction question, the tellus test 21 figure cited is a typical 1900 to present historical earthquake map for the area in question that shows the direction of subduction if one knows that the earthquake color dots from yellow through red represents increasing focal point depths in the Wadati-Benioff zone but it doesn't have a distance scale or locate the trench or onshore volcanos that might allow a computation of the subduction angle at a particular longitude like the problem 115E. Furthermore, the subduction angle question is close to a trick question.  Cliff Frohlich in "Deep Earthquakes" (2006) shows in Figures 10.14 and 10.15 a curving Wadati-Benioff zone of  less than 90 degrees at a cross-section C-C' close to 115E while stating that "Near 120E and beneath about 500 km the near vertical Wadati-Benioff zone bends backwards so that the XXX plate subduction direction turns slightly xxxward." The trench at 115E/10S can be found in any good atlas to identify the trench and major plate involved.
