I must say that I am not angry at your apparent lack of initiative, disappointed maybe, but not angry.
As I said, chemistry is tricky and I don't know the product(s) of oxidation of aniline with KMnO4 & V2O5 off the top of my head either.
None of us is born knowing this stuff, but we do have to study to learn it; "crazy homework" is put together by a prof. whose purpose is to make you think your way through questions, or at the very least hit the books to get the basics.
You need to search (in general) oxidizing agents in org. chem. and more specifically, oxidations with V2O5/KMnO4.
I'm not aware that trifluoroacetic acid (CF3COOH) is an oxidizing agent.
P.S. Do I get at least HALF a snack now ??
