Exercise 31 Page 457

Let's first determine the difference between inductive and deductive reasoning

• Inductive reasoning means we find a pattern to prove something.
• Deductive reasoning requires us to prove something by facts and definitions.

Think about the statement. Is it a fact that when mom goes to the store she buys milk? No, it is not a fact. Just because it has happened historically there is no guarantee that it will happen in the future, which is called a pattern. Therefore, the second sentence uses inductive reasoning to reach the conclusion that mom will buy milk.
