                    (ii)  Section B contains 5 True or False of 1 mark each.
                    (iii)  Section C contains 5 Fill in the blanks of 1 mark each.
                    (iv)  Section D contains 5 VSQ (very short questions) of 1 mark each.
                    (v)  Section E contains 2 questions one of 2 marks and the other of 3 marks.
                3.  The project work given at the end of the paper is to be assessed by the teacher using his/her discretion.

                 (a)  A natural number raised to an integral power (positive, negative or zero) always gives a positive
                     number.
