Erratic
Imaginary
Uncertain
Short-lived
Answer is Right!
Answer is Wrong!
The correct answer is B. Imaginary.
A chimera is a mythical beast that is part lion, part goat, and part snake. In modern usage, a chimera is something that is imaginary or fanciful.
Erratic means unpredictable or inconsistent. Uncertain means not sure or doubtful. Short-lived means lasting for a short time.
While all of these words could be used to describe a chimera, the most accurate synonym is imaginary.
