Exercise : 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 door to such a mess (2). He never drives any of them (3). They  all look old and beat up and leak oil all over the place (4). It is bad for the neighborhood, and it will decrease property value (5).

The conclusion for this argument is  : 

It is bad for the neighborhood, and it will decrease property value.

Additional premises would be preferable, like : His old cars cause so much damage and commotion to the community and the environment. ( This claim could be placed before claim 4. )

Subagruments  : 

The argument has a couple of subarguments. The 2nd, 3rd, and 4th claims are a subargument for the 1st argument. 

Good argument :

In my opinion the argument was not strong. I also believe that the argument was not a valid one. One of his premises is false, and hence the argument becomes invalid. One of his premises could be false; the claim that states, "People do not like living next door to such a mess." If he had stated "I do not like living next door to such a mess" would have made the argument stronger, but it would not have a connection with the conclusion. The conclusion basically states that, the neighbor's actions with his old cars, would be bad for the entire neighborhood. His premises is false because, one person cannot speak on behalf of others, especially when the premises does not provide evidence of the entire neighborhood's opinion.(This is a hasty generalization) .

Overall I felt that this exercise helped me identify keys claims and concepts that are present in a sentence. This exercise also helped me understand the connection within the sentences, and fill in the blanks if the connection was missing. In the end, it was pretty helpful. :)
