How do I convert the mkv file?

Use a program called Any DVD Converter. Ignore the name, its not only for DVD conversion, it will convert your mkv to avi, wmv, rm etc. Get it at this link: any-dvd-converter.com/download.

I recommend Convert X to DVD. It will convert any video file to a playable DVD. vso-software.fr/products/convert_x_to_d.

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.
