II.              Item 2

If you hate Slippery Slope arguments, you will do poorly in class

If you do poorly in class, you will drop out of school.

If you drop out of school, you will commit crimes

If you commit crime, you will go to prison

If you go to prison, you will die of AIDS.

Type of fallacy: Slippery Slope

Analysis: The process of inference:

         Hidden premise: All students who hate Slippery Slope argument will do poorly in class –> factual error

     If you hate Slippery Slope arguments 

 ————>> You will do poorly in class

           Hidden premise: All students who do poorly in class will drop out of school –> factual error)

————>>   You will drop out of school 

               Hidden premise: People who drop out of school will commit crimes –> factual error)

————>>  You will commit crimes 

               Hidden premise: People who commit crimes will go to prison –> factual error)

      ————>>  You will go to prison 

            Hidden premise: People who go to prison will die of AIDS –> factual error)

     ————>>  You will die of AIDS

***The conclusion is unreasonable and unacceptable due to factual error of premises

III.              Item 3

Rooster crow just before the sun rises.
Therefore, roosters crowing cause the sun to rise.

 

Type of fallacy: Post hoc

According to this saying, rooster crow precedes the rising of the sun so roosters crowing cause the rising of the sun. Actually, rooster crows instinctively and the sun rises as its cycle not because of rooster crowing. Therefore, the conclusion that “roosters crowing cause the sun to rise” is false.

  Structure: All cats have four legs                 All S are P

                  I (the dog) have four legs------>>           a is P

                ---------------------------------                        ---------------

                    I am a cat                                              a is S

Type of fallacy: Structural fallacy

  The above argument is invalid. Two premises are true but the conclusion is false due to the inference.
