1.Yes! so easy for me
That's because I study Japanese, so I will always recogize it. Friends of mine are studying Chinese and Korean, so I pretty much learned through them what the languages sound like. But even before that I could tell them apart. Only sometimes I mixed up Korean and Chinese. I think Japanese words sound more.. clear? whereas Chinese sounds very cute but a bit.. like mumbling sounds to me. I can't explain it right in English
