HG_2.3.1 Video Lesson - Intro of the 3 Laws of Deductive Reason

What does the law of detachment allow us to do when given a true hypothesis?

• It allows us to change the hypothesis.

• It allows us to ignore the conclusion.

• It allows us to negate the hypothesis.

• It allows us to conclude the truth of the conclusion.

In the law of syllogism, if 'A implies B' and 'B implies C', what can we conclude?

• C implies A

• A implies C

• C implies B

• B implies A

What is the main idea behind the law of syllogism?

• To combine two conditional statements into one

• To negate both the hypothesis and conclusion

• To separate the hypothesis from the conclusion

• To confirm the hypothesis is true

What does the law of contrapositive involve?

• Switching and negating the hypothesis and conclusion

• Confirming the hypothesis is true

• Combining two conditional statements

• Ignoring the original statement

If 'P implies Q', what is the contrapositive?

• P implies not Q

• Not Q implies not P

• Not P implies not Q

• Q implies P
