Their being fictional helps us to realise that the actual truth-values of premises and conclusions are usually irrelevant to determining whether or not arguments are valid: The first reason is that many people are not very clear about the possible ambiguities of such a statement.

If it is raining then it is cloudy. Roughly, then, an inductively forceful argument is one that is not deductively valid — the truth of the premises would not ensure the truth of the conclusion — but whose premises provide good reason to expect the conclusion to be true rather than false.
