Complete the 12 sentences below. Choose the best answer for each one.
1............... was the finance director who insisted that the launch be postponed, not the marketing team.
Wrong!
Use "It" in an it-cleft to emphasize the person who made the decision: it was the finance director, not someone else.
2It was Dr Marin ............... challenged the committee's assumptions during the hearing.
Wrong!
Use "who" because the emphasized element is a person, Dr Marin.
3It was during the final hour of negotiations ............... the two sides finally accepted the compromise.
Wrong!
Use "when" because the cleft highlights a time, the final hour of negotiations.
4It was in the temporary warehouse ............... the auditors discovered the missing records.
Wrong!
Use "where" because the cleft emphasizes a place, the temporary warehouse.
5............... undermined trust was the management's refusal to release the full report.
Wrong!
Use "What" to form a pseudo-cleft subject meaning 'the thing that undermined trust'.
6What mattered most to the inspectors ............... the revised safety protocols, not the glossy presentation.
Wrong!
Use "were" because the emphasized complement after the pseudo-cleft is plural: the revised safety protocols.
7It was ............... that caused the production delay, not the design software.
Wrong!
Use "the delivery schedule" because an it-cleft after 'was' needs the emphasized phrase, not a full finite clause in this position.
8The question is not whether she resigned; the question is ............... .
Wrong!
Use "why she resigned" after 'The question is' to create a wh-cleft focusing the unresolved issue.
9............... the board rejected was the proposed timetable, not the underlying strategy.
Wrong!
Use "What" because the sentence is a pseudo-cleft: 'what the board rejected' is identified as the timetable.
10It was ............... that the journal agreed to publish the findings, not before.
Wrong!
Use "only after the data were verified" because the sentence emphasizes that publication did not happen before verification.
11It was ............... that the investigation was suspended, not because the witnesses were unavailable.
Wrong!
Use "because the figures were inconsistent" to emphasize the reason for the suspension in an it-cleft.
12All the consultant ............... was summarise the risks that the engineers had already identified.
Wrong!
