Structure of Arguments

My neighbor should be forced to get rid of all the cars in his yard. 1 People do not like living next to such a mess. 2 He never drives any of them. 3 They all look old and beat up 4 and leak oil all over the place. 5 It is bad for the neighborhood, 6 and it will decrease property values. 7

Argument? Yes

Conclusion: My neighbor should be forced to get rid of all the cars in his yard.

Additional premises needed? If a car leaks oil, then it should get fixed, otherwise sold, if it is not in use or in good running condition. a

Identify any subargument: 5 supports 6 and a. 2, 3, 4 ,7 are independent and support the conclusion, 1.

Good argument? Premise 7 is not proven to be true. But if it was then the argument would be good and valid.

This exercise was very useful. It helped me to analyze arguments and identify sentences that are claims and ones that could be possible conclusions.
