Question

Choose the word with the same denotative meaning as formidable in the following passage? ...these difficulties were infinitely more formidable? a. unexpected b. insignificant c. discouraging d. measurable

Answer 1

c I would say and the only other choice is really d
I take the usage of "infinitely" as a qualifier here to indicate the character facing these difficulties has little chance of overcoming them from their own viewpoint. They sound discouraged.
