Yes I was interested about that one as well - apparently it's related to the Proto-Indo-European 'porkos' (and hence the Latin porcus), which I wouldn't have guessed but which makes sense given the p-b-v thing that happens between Indo-European languages. Apparently in English we have a word 'farrow' for a litter of piglets, but I'd never heard of that before.
Being French (that only helped for raspberry though), speaking English and having sufficient knowledge of German, it's remarkably easy to get at least three quarters of them right. I guess that reputation of Dutch to be easy to learn for people who speak Germanic languages is in part well-deserved.
This is the closest foreign language to English - you should be able to get two thirds of them from sounding about right. A smattering of German and French covered the rest.
Great quiz
