Builder inheritance versus class inheritance: 1) The ImageNews builder extends the news builder (builder inheritance). 2) The ImageNews builder class is an instance of (but does not extend) Images, and extends MMObjectBuilder (class inheritance). Since we were discussing builder inheritance, 1) is the statement that is relevant to our topic.
