Question 3 - True or False - 1 mark each - 5 marks

State whether each statement is True or False. Correct each of the false statements by rewriting the statement, changing the bold-printed portions only. No marks will be awarded for simply negating the false statement. Many learners did not correct the false statement - need exercises in doing this before matric.

  1. False - thickest and brightest
  2. False - Hardware 
  3. True - HTML (not technically correct but accepted) or False - Java
  4. True - amazon.com is cyber bookstore.
  5. False - WAP

Question 4 - Dear Doctor Byte ... - 1 mark each - 5 marks

For this question I read the answer to see if the kids 'knew' the answer.  This was the first time such a question was asked.  In future it will get 2 marks each as it required so much writing and thinking.
