1. True or False. When you have two Boolean expressions joined by an or the entire expression will be true if both Boolean expressions are true.

2. True or false. A while loop can have an if statement inside the code block but an if statement can never have a while loop a true branch.

3. When we talk about abstraction, we are referring to __________ the details of the program logic.   A. summarizing

            B. hiding

            C. promoting

                           D. all of the above

4. The three parts and a module are ________, body and return statement

                             A. header

                statement

            }
        }

     }

3. Answer:
         D. all of the above
