There is a wrong order, should not put this sentence at the end of the speech:

It turned out monkeys from the first group took two hours less to train on average. it should be like this:

It turned out monkeys from the first group took two hours less to train on average. The reason was that the researcher expected the smarter group to be easier to train so he smiled to those monkeys and encouraged them a lot during the training. But he didn’t work as hard with the monkeys from the other group.

-------------------
in the speaking, we will need to follow the order in the lecture:

9. So what happened?
10. Well, the researcher trained the monkeys to perform the action and it turned out that on average it took him two hours less time to train the supposedly smart monkeys than these supposedly less intelligent monkeys.
11. Why?Well, it turns out that with the supposedly smart monkeys, the researcher smile them a lot, gave me a lot of encouragement, talked to them a lot, worked hard to communicate with them.
12. But with the monkeys he thought were less intelligent, he wasn't enthusiastic.
13. He didn't try quite as hard, wasn't quite as optimistic.
