Which type of argument is intended to give probable support rather than conclusive proof?

• A. Modus ponens
• B. Deductive argument
• C. Slippery slope
• D. Inductive argument

Answer: (D)

Inductive reasoning provides probable support rather than conclusive proof. In inductive arguments, the premises give evidence for a conclusion but don’t guarantee it; the conclusion is supported to varying degrees and could be false even if all premises are true. The strength depends on factors like sample size, representativeness, and how evidence is gathered. For example, surveying a sample of people and finding most prefer a product lets you predict that the general population will prefer it, but it isn’t guaranteed. This contrasts with deductive arguments, where a valid form such as modus ponens ensures the conclusion follows from the premises with necessity if the premises are true. Slippery slope is more a rhetorical pattern that argues a chain of events without solid evidence for each step, and it isn’t a general method of providing proof, whereas inductive reasoning is the standard approach for showing probable support. Therefore, the type intended to give probable support rather than conclusive proof is the inductive argument.
