This week's book giveaway is in the Agile and Other Processes forum. We're giving away four copies of The Little Book of Impediments (e-book only) and have Tom Perry on-line! See this thread for details.
Which of the following lines of code, if inserted independently at Line 5, will cause the text within the ctherwise tag to display? (Choose all that apply)
D. books.add("Head First");
E. books = null;
Answer is BD,
I thought it would be E. Also the explanation gviven in the book is not satisfying. What is the correct answer?

the answer is C and E. Maybe there is a typo!
A, B and D are wrong because all of them add something to the books list and the list is NOT empty.
