Which word means 'impossible to overcome' (a difficulty)?

• A. credulous
• B. stonewalling
• C. insuperable
• D. portmanteau

Answer: (C)

A difficulty that cannot be overcome is described by insuperable. This word captures the idea of obstacles or problems that are so great or so persistent that they can’t be conquered or surpassed. It suggests a sense of finality in the challenge, something that stands firm against any effort to overcome it. The root idea comes from overcome, with the prefix in- giving the sense of not being able to overcome. Other options miss that specific sense: credulous means gullible or too trusting; stonewalling means to block or obstruct, often to delay; portmanteau is a blended word formed from parts of two or more words. None of these convey the notion of a hurdle that cannot be surmounted, which is why insuperable is the best choice.
