Chapter 3, answer to question 7 (Page 220)
G is incorrect: Apart from the three Wind objects that are ready to be garbage collected, there is also an unreferenced String object (value "1 2", the one that was created in the System.out.println - line). So, there are 4 objects eligible for garbage collection.
The valid answers are A and B, or the text of option G should read "Three objects of type Wind are eligible for garbage collection"
