ABSTRACT
Use a piece of paper or cardboard to mask all but frame 1 on the next page. Read this frame carefully, and write the necessary word ON the programme itself.
When frame 1 is completed, move the cardboard down to unmask frame 2. You will see that the correct answer to frame 1 appears in the right hand margin opposite frame 2. Compare your answer with the printed answer, and then attempt frame 2. Continue like this throughout the programme. In certain frames you will not be required to make a response.
