Final answer:
The word pair that best represents the contrast between incredulous and credulous is naïve : experienced.
Step-by-step explanation:
The analogy incredulous : credulous indicates a contrast between someone who is skeptical or unwilling to believe something (incredulous) and someone who is easily convinced or believes everything (credulous). Therefore, we need to find a pair of words where one represents skepticism or doubt and the other represents trust or easily believing.
Looking at the given options, the word pair that best represents this contrast is c) naïve : experienced. Naïve means lacking experience or judgment and is often used to describe someone who is easily convinced or gullible. Experienced, on the other hand, suggests knowledge gained through practice or exposure, which implies a level of skepticism or critical thinking. Hence, c) naïve : experienced is the correct answer.
