In each of the questions, a sentence is divided into

Solution

• Part B: The error is in part (B) “to team collaboration”.

The correct phrase should be “of team collaboration”. The preposition “of” is needed after “importance” to indicate the relationship between the two nouns. ·         The error in part (D) is the phrase : “he was hoped that”. The correct phrase should be “he had hoped that”. The verb tense is incorrect; “was hoped” is a passive construction that doesn’t fit the context. Instead, the sentence should use the past perfect tense “had hoped” to indicate the manager’s prior expectation. “The manager insisted on the importance of team collaboration, but they were unable to reach an agreement, so he felt frustrated, because he had hoped that they would reach a consensus soon.”
