Directions: Select the words which are opposite in meaning to the underlined…

Solution: The word opposite in meaning to the underlined word is "Unknown".

Key points:

• Renowned — an adjective meaning famous and respected.

• Famous — an adjective meaning widely known; this is a synonym of renowned, not an opposite.

• Unknown — an adjective meaning not known or not familiar; this is the opposite of renowned.

• Heard — a verb meaning perceived by the ear; it is unrelated in meaning and part of speech, so not an opposite.

• Distinguished — an adjective meaning respected or notable; this is similar to renowned, not an opposite.

Therefore, the correct answer is "Unknown" because it means not known or familiar, which contrasts with renowned (famous and respected).
