World War One: Treat of Versailles HELP?

You should really ask your sister *where* she "threw your history notebook out" so you can go find it, as its loss has made you "a tad iffy on the World War One topic". You should also consider calling out the internet repairman as well, because you really should be able to find out stuff about WW1 online. There's clearly something wrong somewhere. Hope this helped.
