Candid is to indirect as honest is to

Analogies, Logical Reasoning /
Question: Candid is to indirect as honest is to
[A].

frank

[B].

wicked

[C].

truthful

[D].

untruthful

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.
