Meaning: 'Redefined' means to change the meaning or understanding of something, in this case, worker identity in the context of the gig economy.

Wrong options:

• transferred: Transferred implies moving something from one place to another, which does not fit the context of changing worker identity.
• submitted: Submitted suggests presenting something for consideration or judgment, which is not relevant to the transformation of worker identity.
• confirmed: Confirmed means to establish the truth or correctness of something, which does not convey the idea of changing or evolving worker identity.

Correct answer: juggle

Explanation: The verb 'juggle' is appropriate here as it conveys the idea of managing multiple tasks simultaneously, which aligns with the context of individuals balancing various gigs. It fits grammatically as it is in the present tense, matching the overall tense of the passage.

Meaning: 'Juggle' means to handle or manage several activities at the same time, reflecting the reality of gig workers balancing different jobs.

Wrong options:

• bring up: Bring up means to introduce a topic or raise an issue, which does not fit the context of managing multiple jobs.
• take after: Take after refers to resembling someone, typically in appearance or behavior, which is unrelated to the context of managing work.
• concentrate: Concentrate means to focus attention on a particular task, which contradicts the idea of managing multiple gigs.

Correct answer: routine

Explanation: The word 'routine' fits well as it refers to a regular or habitual pattern of behavior, which contrasts with the adaptability valued in the gig economy. It aligns grammatically as a noun that completes the sentence's structure.

Meaning: 'Routine' refers to a regular, predictable pattern of activities, which is being challenged by the gig economy's emphasis on flexibility.

Wrong options:

• flexibility: Flexibility suggests the ability to adapt, which is actually a valued trait in the gig economy, making it contextually incorrect here.
• revenue: Revenue refers to income generated, which does not relate to the concept of stability in work patterns.
• delegation: Delegation means assigning tasks to others, which does not fit the context of contrasting with stability.

Correct answer: safeguards

Explanation: The term 'safeguards' is appropriate as it refers to protective measures or provisions, which are lacking in the gig economy. It fits grammatically as a plural noun that complements the sentence structure.

Meaning: 'Safeguards' means measures taken to protect something, in this case, the rights and benefits of workers in the gig economy.

Wrong options:

• licenses: Licenses refer to official permissions, which do not relate to the protective measures needed for workers.
• indiscretions: Indiscretions refer to lack of discretion or judgment, which is irrelevant to the context of worker protections.
• forces: Forces imply coercive power or influence, which does not fit the context of lacking protective measures.

Correct answer: pushing

Explanation: The gerund 'pushing' fits grammatically as it indicates an ongoing action that is a result of the challenges posed by the gig economy. It aligns contextually with the idea of urging a reconsideration of the social contract.

Meaning: 'Pushing' means to encourage or compel someone to take action, in this case, to rethink the relationship between employers and employees.

Wrong options:

• which push: 'Which push' is grammatically incorrect as it does not fit the sentence structure; it lacks the necessary form to convey ongoing action.
• pushed: 'Pushed' is in the past tense, which does not match the present continuous context of the sentence.
• and push: 'And push' is also grammatically incorrect as it disrupts the flow of the sentence and does not convey the intended meaning.
