Question

complete the sentence.
the red ball is bigger ___ the blue ball.
options: sleep, who, than

Explanation:

To complete the sentence "The red ball is bigger ____ the blue ball", we need a word that is used in comparative structures. "Than" is used to introduce the second element in a comparison (when using comparative adjectives like "bigger"). "Sleep" is a verb and "who" is a pronoun used for people, so they don't fit here.

Answer:

than
