For questions 1-18, name the type of logical fallacy being used.

1. Dr. Oz was a featured health expert on the “Oprah Winfrey Show” and says that a specific brand of weight loss product is effective at burning fats and calories. Therefore, it must be true.

2. I thought you cared about homeless people, but you did not attend the “concert for a cause” to support homeless people in Canada.

3. Every country is fighting the COVID-19 virus because it is a global pandemic.

4. It rained so hard when the power went off. The rain has caused the power to go off.

5. Family cohesion is correlated to volume of crimes. Therefore, family cohesion causes crime.

6. If you cannot justify that mermaids don’t exist, then they must exist.

7. Get enough sleep daily and be healthy or continue to go to bed late each night and be sick. These are the only two options.

8. You must follow what your parents told you because parents are always right.

9. Andy was accused of a crime. There was no solid evidence to prove that Andy committed the crime. Therefore, the accuser was wrong.

10. The pandemic will be over this year; a lot of people will lose their jobs and loved ones if it won’t.

11. You obey my house rules, or you cannot go out with your friends.

12. Mickey Simpson and Bugsy Humperdinck are running for President. Mickey argues that women won’t possibly vote for Bugsy as he has a religious conviction that tends him to become pro-life.

13. A commercial claim that a certain brand of toothpaste is the world’s leading brand as more than 80% of dentists recommended its use.

14. I do not accept the claim that human beings came from apes. Otherwise, my biological predecessors would be monkeys. Therefore, Charles Darwin’s theory of evolution must be wrong.

15. A pregnant woman tells the unmarried obstetrician-gynecologist that she doesn’t believe in her judgment because she has never been pregnant.

16. If you don’t want to drive from Boston to New York, then you will have to take the train.

17. New England Patriots quarterback Tom Brady likes his footballs slightly underinflated. The “Cheatriots” have a history of bending or breaking the rules, so Brady must have told the equipment manager to make sure that the footballs were underinflated.

18. Whenever our smoke detector beeps, my kids eat cereal for dinner. Therefore, the loud beeping sound must make them want to eat cereal.
