Question

complete the analogy.
anxious is to calm as amateur is to
professional beginning
athlete experience

Explanation:

In the analogy, "anxious" and "calm" are antonyms (opposites). To complete the analogy, we need an antonym for "amateur". "Amateur" refers to someone who does something as a hobby or without professional training, so its antonym is "professional" (someone who does something as a profession with training/skill). "Beginning" is a noun related to start, "athlete" is a person in sports, "experience" is a noun about knowledge from doing, none are antonyms of "amateur".

Answer:

professional
