Example -- Humans cannot fly. Therefore, Jenny cannot fly.
Analysis -- The premise that would make this argument strong or valid is "Jenny is a human being." Jenny could be either a human being, an animal, or insect.This is a logical argument, but it also needs to be repaired.The only statement that needs to be added is that "Jenny is a human." If we all know that Jenny is a human, then the argument would be both stronger and valid. A better way to state this argument is "Humans have never been able to fly, and since Jenny is a human, she obviously cannot fly." The argument is now complete and sounds better than the first sentence. The statement "Humans cannot fly" is common sense, and it does not need any additional background information. However, the argument still needed to conclude that "Jenny is a human being" in order to make this argument valid and stronger.
Very nice example. This is true because Jenny can either be an object or an animal. It is to vague to assume that Jenny is human, but if it is stated that Jenny is human then it would make the argument strong or valid. This statement does need to be repaired in order to make the argument valid or strong. All they sentence would need is to state that Jenny is human. This is a good example and simple to understand the concept of repairing arguments. Good job. Its true that humans can not fly, but what if Jenny was a bird then she would be able to fly, so this statement does need to include that Jenny is human.
