Once we have identified the main conclusion, we can treat the remaining parts of the argument as premises used to support the conclusion.

We now pose the question, Is the above argument a good argument, in the sense previously mentioned (does it give good reasons to accept its conclusion)?

To answer this you should have determined that the conclusion is that one should have working fire alarms in their house.

What are the premises given which support the conclusion? Basically, a story is taken from the news that recounts what almost happened to a household which did not have working fire alarms. Now consider the following questions:

These questions bring out a fundamental point in argument analysis: Many times if you happen to agree with a conclusion before reading the argument, there is a greater chance that you will judge the argument for that conclusion as a good argument rather than a bad argument. This leads to the following two observations:

  1. When evaluating whether an argument is good or not, it is important to examine the actual argument itself and ignore any previous conceptions you may have about the truth or falsity of the argument's conclusion.
  2. It is possible that a conclusion is true, even when a particular argument for the conclusion does a poor job in supporting the truth of the conclusion.
