Ah, the old Premack principle conundrum. Let's see, if Jeff spends the most time on blocks, then that must be his least preferred activity. So B is the way to go. Piece of cake, just like building a tower with those blocks!

Haha, this question is a real block-buster! I'm gonna go with D - playing with crayons will serve as a reinforcer for playing with trucks. Why? Because who doesn't love a good crayon-drawing session, am I right?

Hmm, I'm not too sure about this one. I was thinking C, but now I'm second-guessing myself. Didn't the Premack principle say something about the more preferred behavior reinforcing the less preferred one? Guess I better review my notes.

But playing with trucks is more preferred by Jeff, so it would serve as a reinforcer for playing with blocks.

I think the answer is B. Playing with trucks will serve as a reinforcer for playing with blocks. The Premack principle states that a more preferred behavior can be used to reinforce a less preferred behavior, and since Jeff spends the most time playing with blocks, that must be his least preferred activity.
