Meaning: 'Witness' means to see or experience something, particularly an event or situation, which in this case refers to observing the findings of the study.

Wrong options:

• Corrborate: 'Corrborate' is a misspelling of 'corroborate,' which means to confirm or give support to a statement or theory, but it does not fit the context of directly observing the study's findings.
• Testify: 'Testify' implies giving a formal statement or evidence, usually in a legal context, which does not align with the casual observation of a study's results.
• Confirm: 'Confirm' means to establish the truth or correctness of something, but it lacks the nuance of direct observation that 'witness' conveys.

Correct answer: divisions

Explanation: The term 'divisions' is appropriate as it refers to separations or distinctions among colleagues, fitting the context of job titles creating barriers. It is plural, matching the context of multiple instances of division.

Meaning: 'Divisions' means separations or distinctions that create differences among groups, in this case, among colleagues due to job titles.

Wrong options:

• compartments: 'Compartments' refers to separate sections within a larger space, which does not accurately convey the social context of job titles creating distinctions among people.
• demarcations: 'Demarcations' implies clear boundaries or limits, which is too formal and does not capture the social implications of job titles as effectively as 'divisions.'
• partitions: 'Partitions' suggests physical separations, which does not fit the abstract concept of social divisions created by job titles.

Correct answer: forgo

Explanation: The verb 'forgo' fits grammatically and contextually as it means to decide not to have or do something, which aligns with the willingness of workers to give up a pay rise for a better title.

Meaning: 'Forgo' means to decide not to do or have something, indicating a choice to prioritize a job title over financial gain.

Wrong options:

• revoke: 'Revoke' means to take back or withdraw something, which does not fit the context of willingly giving up a pay rise.
• forbear: 'Forbear' means to refrain from doing something, but it is less commonly used and does not convey the same active choice as 'forgo.'
• resign: 'Resign' means to voluntarily leave a job, which is not the same as choosing to give up a pay rise for a title.

Correct answer: reaching

Explanation: The word 'reaching' fits grammatically as it is a present participle that describes the state of vanity growing to a certain level. It conveys the idea of vanity attaining a significant level, which is appropriate in this context.

Meaning: 'Reaching' means arriving at or achieving a certain level or extent, indicating that vanity is growing to alarming proportions.

Wrong options:

• attaining: 'Attaining' implies achieving something through effort, which does not fit the context of vanity's growth as effectively as 'reaching.'
• touching: 'Touching' means to come into contact with something, which does not convey the idea of growth or extent in this context.
• finding: 'Finding' refers to discovering something, which does not align with the concept of vanity increasing.

Correct answer: labelled

Explanation: The word 'labelled' fits grammatically as it is the past participle used in a passive construction, indicating that individuals do not want to be categorized in a subordinate role. It aligns well with the context of job titles and social status.

Meaning: 'Labelled' means to be categorized or identified in a certain way, in this case, as subordinate, which is undesirable for the workers mentioned.

Wrong options:

• defined: 'Defined' suggests setting clear boundaries or meanings, which does not capture the social implications of being categorized as subordinate.
• marked: 'Marked' implies being distinguished or noted, which does not convey the same sense of unwanted categorization as 'labelled.'
• identified: 'Identified' means recognized or established, but it lacks the connotation of social categorization that 'labelled' provides.

Correct answer: place

Explanation: The verb 'place' fits grammatically as it indicates the act of positioning emphasis on ability. It is appropriate in the context of discussing how job titles affect perceptions of ability.

Meaning: 'Place' means to put or set something in a particular position, in this case, emphasizing ability through job titles.

Wrong options:

• set: 'Set' can also mean to place, but it is less specific in this context and does not convey the same nuance of emphasis as 'place.'
• fix: 'Fix' implies making something stable or permanent, which does not fit the context of emphasizing ability through job titles.
• allocate: 'Allocate' means to distribute or assign, which does not align with the idea of emphasizing ability in the context of job titles.
