Which word describes a persuasive but valid-sounding argument?

• A. Cogent
• B. Convoluted
• C. Decorum
• D. Capricious

Answer: (A)

A cogent argument is one that is clear, well-reasoned, and convincing. It presents relevant evidence and logical connections so the reader finds the conclusion persuasive because the reasoning holds up. The phrase “persuasive but valid-sounding” fits well here because cogent arguments strike a balance: they seem valid because their logic is sound and the premises appear credible, not merely because they rely on flashy rhetoric.

Convoluted describes something tangled and confusing, which typically undermines persuasion rather than supports it. Decorum refers to proper behavior or manners, not the quality of an argument. Capricious means unpredictable or whimsical, which has nothing to do with how persuasive or logically sound an argument is.
