 I'll give it a try (spoiler?) | Comment 1 of 5
Starting with statement 1 as a given, the running deductions are:
Jumping to 6: Some alligators know that flying fish live in the trees
Then to 2: Some alligators prefer caramel to chocolate
Then to 7 (this is tricky):  Some alligators might be (i.e. are not automatically excluded from being) steeplechasers
Then to 5: It is possible that some alligators watch hockey (since some alligators might be steeplechasers.
Then to 3: Since certain days are set aside for alligators to watch hockey, there must indeed be alligators that watch hockey (or what's the point?) therefore: Some alligators watch hockey, and those alligators must also be steeplechasers (consistent with 4,5).
Then to 8: Some alligators are vegetarians

Answer:  Some alligators are vegetarians
