I just discovered an error in the book which was copied over into the homework problem (problem 7 of Problem Set 2).

The last sentence:

     What information is not dropped?

should read:

What information is lost?

And, while I am at it, I think it would be useful to add an extra sentence to the beginning of the problem set, to wit:

     Implement the following functions using AND, OR, and NOT
     logic gates. The inputs are A,B, and the output is F. In each case
     (a, b, and c), you are to use only the minimum number of AND and OR
     gates. 

Hope that helps.
