Question

there are a lot of prefixes that mean not. these include the prefixes non- and un-. when either of them come at the beginning of another word, the meaning will be the opposite of the root word. for example, something unusual doesn’t happen very often, or not usually. a nontraditional school is not traditional. what does the word unknown mean in the passage below? halcyon, lewis and lenore all knew they would be on the team. however, the identity of the fourth player was still unknown. options: a halfway known, b known again, c before being known, d not known

Explanation:

The passage explains that prefixes like "un -" mean "not". The word "unknown" has the prefix "un -" and the root "known". So "unknown" should mean "not known", which matches option D.

Answer:

D. not known
