(h) Given that p is true and q is false, construct a truth table that shows the truth value for the
following expression: (2 Marks)

(i) Define the term ‘expert system’ (1 Mark)
QUESTION TWO
a) Briefly explain the meaning of the following concepts. Give one example of potential career for
each case
(i) Linguistic Intelligence (2 Marks)
(ii) Spacial intelligence (2 Marks)
(iii) Bodily kinesthetic intelligence (2 Marks)

(ii) Intelligent agent (2 Marks)
(iii) Agent environment (2 Marks)
(b) Describe any two applications of a robot in the industry (2 Marks)
(c) State and explain three types of mobile robots (3 Marks)
(d) Briefly explain four characteristics of a robot (4 Marks)
