Boxing/Unboxing isn't covered until Chapter 4. Question 11 should not be in chapter 3.

Boxing and unboxing is mentioned in Chapter 3, I think on pages 102, 103, and 106. It talks about how generics avoid boxing and unboxing, but it doesn't really spell out what they are.

So I agree that the question doesn't fit well in Chapter 3. There should have been a sidebar that explained what boxing and unboxing are in better detail.
