[plt-scheme] solution for exercise 11.2.4

Not true. You answered the question already and they are *trivial*  
question. I just want you to learn to think about what you're doing  
instead of just following something in a rote manner. Once you know  
how to think about it, you'll internalize and empower yourself to  
apply such things in situations where you never expected it.

Try again. I expect an answer in 10 mins.
