Meaning: 'Was made' means that an action (the attempt) occurred in the past, emphasizing that something was done rather than who did it.

Wrong options:

• making: 'Making' is a gerund and does not fit grammatically as it cannot serve as the main verb in this passive construction.
• make: 'Make' is in the base form and does not agree with the past tense context of the sentence, making it incorrect here.
• made: 'Made' is the past participle but lacks the auxiliary verb 'was' to form the passive voice, thus it does not fit.

Correct answer: pushed down

Explanation: The phrase 'pushed down' indicates a reduction in decision levels, which fits contextually as it suggests a lowering of authority or responsibility. This aligns with the overall intent of the sentence to describe changes in supervision.

Meaning: 'Pushed down' means to lower or reduce something, in this case, the levels of decision-making authority.

Wrong options:

• put off: 'Put off' implies delaying something, which does not fit the context of changing decision levels.
• turned: 'Turned' lacks clarity in this context and does not convey the intended meaning of reducing levels.
• set up: 'Set up' suggests establishing something rather than reducing it, making it contextually inappropriate.

Correct answer: trained

Explanation: The word 'trained' fits grammatically as it is in the past tense, matching the overall narrative of past actions taken regarding the managers and supervisors. It indicates that these individuals received instruction in leadership methods.

Meaning: 'Trained' means to have been taught or instructed in specific skills or methods, in this case, group leadership methods.

Wrong options:

• fired: 'Fired' implies termination of employment, which contradicts the context of providing training.
• overlapped: 'Overlapped' does not fit grammatically or contextually as it suggests a different meaning related to redundancy or coincidence.
• deduced: 'Deduced' means to conclude or infer, which does not align with the context of receiving training.

Correct answer: endeavored

Explanation: The word 'endeavored' fits grammatically as it is in the past tense and indicates an effort made by the managers and supervisors to apply their training. It aligns with the context of attempting to use their skills effectively.

Meaning: 'Endeavored' means to make a serious effort or attempt to do something, in this case, to apply their leadership skills.

Wrong options:

• expanded: 'Expanded' suggests increasing or enlarging something, which does not fit the context of making an effort to use skills.
• gathered: 'Gathered' implies collecting or assembling, which does not convey the intended meaning of effort in applying skills.
• covered: 'Covered' suggests discussing or addressing something, which does not align with the context of making an effort.

Correct answer: will be labelled

Explanation: The phrase 'will be labelled' is in the future passive voice, indicating that the changes are expected to be labelled in the future. This fits grammatically and contextually as it refers to a forthcoming action regarding the experimental changes.

Meaning: 'Will be labelled' means that at a future time, the changes will receive a specific name or designation, in this case, the 'participative program.'

Wrong options:

• labelled: 'Labelled' is in the past tense and does not indicate a future action, making it incorrect in this context.
• was labelled: 'Was labelled' is also in the past tense, which does not fit the future context of the sentence.
• were labelled: 'Were labelled' is in the past tense and does not align with the future expectation indicated in the sentence.
