There are a few corrections to the explanations of the quiz
solutions. (The solution answers are correct, but some of the
explanations are incomplete, etc.) The on-line version has been
corrected, but the changes are reproduced below as well.

Question 5, choice A: new Test () has type Object

This choice is incorrect because new Test() is not a legal
expression. class Test has an explicitly defined constructor, and
that constructor requires a parameter. [The original explanation was incorrect.]

Question 6, choice B:

The solution says "Answer b is incorrect because fourth test is assigned the value of
firstTest on line . "

This should say "on line 6."
