Choose the word that best completes the analogy. Then, write a few sentences explaining why it is the best answer.

Answer:

The word "unusual" best completes the analogy. The relationship between "peculiar" and "ordinary" is that they are antonyms, or words with opposite meanings. To maintain this relationship in the second part of the analogy, the word paired with "common" must also be its opposite. "Unusual" is an antonym for "common" and a synonym for "peculiar," which perfectly completes the logic of the analogy.
