Which of the following statements about arguments is true?

The statement that arguments must have at least one premise is indeed true. In the structure of an argument, a premise provides the supporting reasons or evidence that lead to a conclusion. An argument without a premise would lack the foundational reasoning needed to support its claim, making it incomplete. A valid argument typically contains multiple premises that collectively reinforce the conclusion. This structural requirement highlights the essential role premises play in forming coherent and persuasive arguments.

In contrast, other options present misinterpretations of the nature and function of arguments. For instance, while emotional appeals can be part of some arguments, they are not a requirement for an argument to exist. The possibility of disputing arguments is a fundamental aspect of critical thinking, as arguments are often subject to analysis and counterarguments in discussions. Furthermore, arguments can manifest in both written and spoken forms, which broadens their applicability beyond just written communication.
