Candid is to indirect as honest is to
Question: Candid is to indirect as honest is to
[A].frank
wicked
truthful
untruthful
[A].
[B].
[C].
[D].
Answer: Option D
Explanation:
Candid and indirect refer to opposing traits. Honest and untruthful refer to opposing traits. The answer is not choice a because frank means the same thing as candid.Wicked (choice b) is incorrect because even though it refers to a negative trait, it does not mean the opposite of honest. (Choice c) is incorrect because truthful and honest mean the same thing.
