1. We are required to explain whether this argument is an inductive or deductive argument. It is a deductive argument.
A deductive argument states an existing theory or a general observation and then tests if the theory can be used to reach specific conclusions. It is unlike an inductive argument, which develops a theory or makes broad generalizations from specific observations.
2. In the argument above, the writer assumes that "we are an intelligent species" and concludes that "the use of our intelligence gives pleasure."
