repairing arguments

Normally, when in a conversation, it is rare for someone to state every single premise of an argument so that those around him can understand it to be a strong or a valid argument. People often times just assume that everyone else understands what he is speaking about; nothing has to be justified as strong or valid because it’s not essential for us to state all the premises that come along with the argument. However, many statements are in need of repairing. For example: “Tom’s car is running out of gasoline. He needs to get to the gas station as soon as possible before his car dies.” As of now, that statement would not be a very good argument because the conclusion and the premise do not complement each other. If instead, you add another premise that verifies some information we normally assume to be true, it would strengthen the argument. For example, adding “It is crucial for a car to have gasoline in it in order for the car to drive” verifies to the reader that a car needs gasoline in order for it to function properly. With that additional premise given, it reveals the hidden premise to the reader and strengthens the beginning argument.
