It's always very obvious, and the idea that some people are still doubtful of that is extremely annoying.

so why 30 people choosed the wrong answer of picker "dont know"

Multiple possible reasons.  It's harder to tell when both samples are smaller.  The 60fps one didn't seem to be locked, so it often dropped--that's the biggest one.  You have to be watching the video in a browser that supports 60fps, and you have to remember to select the option, which everyone might not have done.

There probably are some people out there who can't tell, or at least don't care enough to try to tell, but there are still those who insist that NO ONE can tell.  It's just not true; most people can.  Yet the subject just keeps coming up as though it's still some mystery.
