In the following multiple choice exercise:
"A lot of people are ... about the benefits of nuclear power."
A disbelieving B sceptical C incredulous D unconvincing
The answer key gives "B sceptical" as the correct answer. However, I really can't see why "C incredulous" is incorrect here. Could somebody give me a hand with this one, please? Thanks
I am not a teacher, but I will do my best.
It sounds quite like in Spanish. Escéptico is more like Incrédulo, but still there is a subtle difference.
Incredulous: Unwilling to admit or accept what is offered as true. Disbilief.
Scepticism implies unwillingness to believe without conclusive evidence. Uncertainty.
From Merriam-Webster.synonyms: uncertainty, doubt, dubiety, skepticism, suspicion, mistrust mean lack of sureness about someone or something.
Uncertainty may range from a falling short of certainty to an almost complete lack of conviction or knowledge especially about an outcome or result <assumed the role of manager without hesitation or uncertainty>.
doubt suggests both uncertainty and inability to make a decision <plagued by doubts as to what to do>.
dubiety stresses a wavering between conclusions <felt some dubiety about its practicality>.
skepticism implies unwillingness to believe without conclusive evidence <an economic forecast greeted with skepticism>.
suspicion stresses lack of faith in the truth, reality, fairness, or reliability of something or someone <regarded the stranger with suspicion>.
mistrust implies a genuine doubt based upon suspicion <had a great mistrust of doctors>.
I hope it helps.
