You could form French questions in several ways. The first way (and simplest, if I may add) is by raising your pitch which indicates an earlier statement becomes a question i.e "Il mange" is a statement when your pitch is lower but becomes a question when you raise your pitch (on the last word in the sentence). You could also use inversion. Normally, in a sentence, you will have the Subject+Verb(+object)- for example, "elles sortent en voiture" (The girls go out in a car). For inversion, all you have to do is make the verb your headword- verb+subject(+object) and your question mark so you have this- Sortent-elles en voiture? With inversion, you do need a hyphen to join the verb and the subject. There are other ways but that's it for now. Hope this helps!
I agree with dodumosu and emmaliv. Report it, but perhaps they wanted the more literal "It is eating my food, why?"
"il" does mean "he", but in French every word has gender and some male nouns would be considered "it" in English, but "he" in French. http://dictionnaire.reverso.net/francais-anglais/il
