Using Exhibits 1.5 and 1.6 as a guide, draw up graphs to illustrate the inductions and deductions in the following statements. (If there are gaps, supply what is needed to make them complete arguments.)

therefore, we may conclude that money supply is the basic economic variable.

b Research studies show that heavy smokers have a higher rate of lung cancer than do non-smokers; therefore, heavy smoking causes lung cancer.

c Show me a person who goes to church regularly, and I will show you a reliable worker.
