Structural unemployment from specialisation risks

Steps:

• Identify specialisation as focusing production on specific goods like steel, toys, and textiles to gain efficiency.
• Recall disadvantages include vulnerability to market changes, affecting workers' jobs.
• Evaluate options: A relates to affordability, not direct worker impact; C describes diversification, opposite of specialisation; D involves consumer choice, irrelevant to workers.
• Select B as it matches the risk of job loss from demand shifts.

Why B is correct:

• Structural unemployment occurs when workers' specialised skills become obsolete due to changes in global demand, as defined in labour economics, leaving them mismatched for new jobs.

Why the others are wrong:

• A: Specialisation often enables trade benefits, improving affordability, not hindering it.
• C: Specialisation requires narrow skills, not learning variety.
• D: Choice overload is a consumer issue, not a worker disadvantage of specialisation.

Final answer: B
