The rapid advancement of artificial intelligence has [1] profound questions about the future of human labour, as machine-learning systems increasingly perform tasks once thought to require uniquely human judgement. Automation has historically [2] physical, repetitive labour, but contemporary AI systems are now encroaching upon cognitive and creative domains previously considered immune to mechanisation. Economists remain divided over whether this new wave of automation will translate [3] net job losses or, as with previous technological revolutions, ultimately create more employment than it destroys. What distinguishes the current moment, however, is the sheer [4] at which these systems are being deployed across nearly every sector simultaneously, leaving little time for workers to retrain or for institutions to adapt. Policymakers are therefore under mounting pressure to develop frameworks — from universal basic income to mandatory retraining programmes — that can [5] the transition without leaving vast segments of the workforce permanently displaced.

   • A. asked
   • B. lifted
   • C. risen
   • D. posed ✓

   'Pose a question' is the fixed collocation for an abstract subject — a development, phenomenon, or advancement — giving rise to an issue requiring consideration; 'has posed profound questions' is standard academic phrasing. 'Asked' is used for a person or a directly quoted context, not naturally for an abstract subject like 'advancement'. 'Lifted' does not collocate with 'questions'. 'Risen' is intransitive and cannot take 'questions' as an object, making it grammatically impossible here.

2. Blank [2]
   • A. replaced
   • B. substituted
   • C. displaced ✓
   • D. superseded

   'Displaced labour' is the standard economic term for workers or work being removed from their previous position by a competing force such as automation. 'Replaced' is grammatically possible but more commonly used naming what did the replacing, and lacks the specific labour-market connotation of 'displaced'. 'Substituted' requires the preposition 'for' to work here. 'Superseded' implies something rendered obsolete by a newer version, a slightly different sense than removing workers from jobs.

3. Blank [3]
   • A. to
   • B. into ✓
   • C. as
   • D. toward

   'Translate into X' is the fixed phrasal construction meaning to result in or become manifest as a particular outcome — 'translate into net job losses' is standard economic phrasing for a cause leading to a measurable effect. 'Translate to' is used more for converting units or measurements. 'Translate as' would imply interpretation or naming rather than causal consequence. 'Translate toward' is not an established collocation.

4. Blank [4]
   • A. rate
   • B. pace ✓
   • C. speed
   • D. velocity

   'Pace at which' is the standard fixed collocation in English for describing the rate of progress of a process over time. 'Rate at which' is close and grammatically correct, but 'pace' is overwhelmingly preferred specifically for the rhythm of an ongoing process like technological deployment. 'Speed at which' is used more for physical velocity. 'Velocity' is a technical physics term, inappropriate for an abstract societal process.

5. Blank [5]
   • A. manage
   • B. cushion ✓
   • C. ease
   • D. facilitate

   'Cushion the transition' is the precise idiomatic phrase for softening the impact of a difficult change so that it is less harmful to those affected — it directly relates to 'without leaving... permanently displaced'. 'Manage' and 'facilitate' are more neutral, describing oversight or enablement without implying protection from harm. 'Ease' is close in meaning but less specifically tied to the social-protection policy language that 'cushion' carries.
