Hi Install AppMgr III https://play.google.com/store/apps/detai... When you install any apps after that, it will automatically tell you if any app is movable to SD card. Alternatively, you can open the app and see a list of movable apps. BTW, Xperia M should have enough space to install quite a lot of apps, so do you really need to do it?
If you still feel so, then above is the procedure.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
