What does 'dupe' refer to in terms of a person's character?

The term 'dupe' in relation to a person's character specifically refers to someone who is easily deceived or tricked. This characteristic highlights vulnerability or gullibility, implying that the individual can be manipulated or fooled by others. Such a person may often take things at face value without skepticism, making them susceptible to dishonesty or deception.

In contrast, the other options describe different character traits that are not aligned with the concept of being a 'dupe.' For instance, being wise indicates a depth of understanding and discerning judgment, which is the opposite of being easily deceived. An authoritative figure is someone who holds power or influence, typically characterized by a strong, commanding presence, rather than naivety. A quick decision-maker suggests someone who can evaluate information swiftly and make choices efficiently, demonstrating decisiveness rather than susceptibility to manipulation. Therefore, the correct interpretation of 'dupe' clearly aligns with the idea of being easily misled or tricked.
