Lexis and structure: Choose the option that best completes the gap. The committee ___ to announce its decision the next day.

“The committee” is treated as one group here, so the verb is singular: “is expected”. The word “its” later in the sentence confirms the committee is acting as one body.

“Are expected” and “have expected” use plural verbs, which do not match the single unit. “Have expected” also does not make sense, since the committee is the one being expected to act, not the one expecting.

“Is expected to announce” means people believe the committee will announce its decision.
