what does mr mckee tell nick about gatsby in chapter 2

He doesn't say anything about Gatsby. There is a mistake on the lesson plan that I found in several places on the internet. The question on the plan says "What does Mr. McKee tell Nick about Gatsby?" See below:

In the answer section the question reads:

8. What does Catherine tell Nick about Gatsby?

Answer: She tells Nick that Gatsby is the nephew of Kaiser Wilhelm, another rumor which adds to Gatsby’s mysteriousness.

**Added – Additionally Catherine says that is how Gatsby got his money. Kaiser Wilhelm was the ruler of Germany during World War I (source Spark Notes).
