Fallacy

Determine which of the following statements are logical arguments and which are fallacies. If

1. Almost all the students I talked to said that they didn’t like the senator. I’m sure he’ll lose

6. I had an internship at a government agency last summer, and no one there worked very
hard. Government workers are lazy.
7. It’s a clear principle of law that people are not allowed to yell “Fire!” in a crowded theater.
By permitting protestors to hold a rally downtown, Judge Cohen is allowing them to do just
that.

9. Schools are like families; therefore, teachers (like parents) should be allowed to discipline
their kids.
10. Everybody knows that staying out in the rain can make you sick.
11. When we had a draft in the 1960s, the crime rate was low. We should bring back the draft.

14. If you aren’t part of the solution, you’re part of the problem.
15. All people are mortal. James is a person. Therefore, James is mortal.

copy something from someone else?
17. First, the government stops us from buying assault rifles. Then, it limits the number of
handguns we can buy. What will come next? Soon, they’ll try to take away all our guns.
18. Shakespeare was the world’s greatest playwright; therefore, Macbeth must be a great play.
19. Last month, I bought a new computer. Yesterday, I installed some new software. This
morning, my computer wouldn’t start up. The new software must be causing the problem.
20. Ellen DeGeneres is against testing pharmaceutical and cosmetics products on animals, and
that’s good enough for me.
