If you mean open office documents, then yes, OpenOffice can be opened in a computer without it under certain conditions. One is that the document was saved as the type of program that the computer you're working on accepts. For instance, if you try to open an OpenOffice Writer document that has been saved as a Word 97 document and the computer has Word installed on it, it should open and work just fine.
You can do the same with all the OpenOffice versions of the Microsoft products. So you could save an OpenOffice Impress as a Powerpoint document and open it in powerpoint just fine. You may run into glitches here and there but it usually converts pretty well for me.
However, if it's just saved as an . Otf file and your computer doesn't have open office installed, it won't work. But I would just install open office, it's free and very easy to download from openoffice.org.
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.
