I don't like leaving that entire test available online, so I'll post my response to you here:

1 - 31 are correct.

Incorrect = 32

33 and 34 are correct, but they sure are clumsy, aren't they?

35 is odd -- your second sentence implies that baseball (what? the ball? the game?) teaches you about itself ... ???

In 36, please tell me which ONE noun "which" refers to.

37 - 47 are correct.

48 is missing a comma.

49 and 50 are correct.
