Given data

• We need a word that completes: "…do not look _____."
• Options: unique, different, likely, alike.

Concept/Approach
Look alike is an idiomatic pairing meaning "appear similar." The negative form "do not look alike" is the standard way to say their appearances are not similar. Other options are ungrammatical or shift meaning.

Option analysis
alike — idiomatic complement to look meaning "similar in appearance." ✅different — would require look different from each other; as a one-word complement it is less idiomatic than alike in this test pattern. ❌unique — means one of a kind; does not fit the comparative structure with twins. ❌likely — means probable; wrong part of speech/meaning. ❌
