Question
(1) (a) Determine the validity of the following argument using Venn diagrams
Everyone who is sane (of sound mind) can do logic. Anyone who is not
sane is not fit to serve in a jury. Politicians cannot do logic. Therefore any
politician is not fit to serve in a jury.
(b) Determine the validity of the following argument by first writing the
argument in symbolic form:
If interest rates fall, then the economy will improve. If the economy
improves, then the unemployment will drop. In order for the Green party
to win election, it is necessary that the unemployment drop. Therefore a
sufficient condition for the Green party to win election is that interest
rates fall
