It's a common warning for emulators. In case of emulator there are no actual sensors that's why it unable to create sensor port. Moreover, this warning appears during the boot of the emulator.
If you stop it after this message it is not right. You should wait more until emulator boot.
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.
