⏰ 制限時間: 20分
Paragraph A
The rapid advancement of artificial intelligence (AI) has ignited a global debate about its potential impact on employment. While technological progress has historically created new industries and jobs even as it displaced older ones, many economists now argue that AI represents a fundamentally different kind of disruption — one that threatens not just manual labour but cognitive tasks that were previously considered the exclusive domain of human intelligence.
Paragraph B
The automation of routine tasks has been underway for decades. Factory robots have long replaced assembly-line workers, and automated teller machines reduced the demand for bank tellers in the 1980s and 1990s. However, until recently, tasks requiring judgement, creativity, or social interaction were thought to be beyond the reach of machines. This assumption has been shattered by advances in machine learning, natural language processing, and computer vision. AI systems can now diagnose diseases with a level of accuracy that rivals experienced physicians, write coherent articles, compose music, and even engage in complex legal analysis.
Paragraph C
A widely cited 2013 study by economists Carl Benedikt Frey and Michael Osborne at the University of Oxford estimated that approximately 47 per cent of jobs in the United States were at high risk of automation within the following two decades. The study identified occupations such as telemarketers, data entry clerks, and accountants as particularly vulnerable. Critics of this research argue, however, that such projections overestimate the pace of technological adoption and fail to account for the inertia inherent in labour markets and regulatory frameworks.
Paragraph D
Rather than eliminating jobs outright, some researchers propose that AI is more likely to transform them. In this view, AI becomes a collaborative tool that augments human capabilities rather than substituting for them entirely. Radiologists, for example, may use AI to handle the initial screening of thousands of images, freeing their time for complex cases requiring nuanced interpretation. Similarly, lawyers may rely on AI to conduct document review and legal research, allowing them to focus on courtroom strategy and client relationships. Proponents of this “augmentation thesis” contend that productivity gains driven by AI will ultimately generate new categories of employment, much as the invention of the spreadsheet eliminated many bookkeeping roles while simultaneously creating the profession of financial analyst.
Paragraph E
Not everyone is convinced. Critics point out that the benefits of AI-driven productivity are likely to accrue disproportionately to capital owners and highly skilled workers, widening existing inequalities. Workers in middle-skill occupations — those involving routine cognitive tasks such as data processing, paralegal work, and customer service — face a “hollowing out” effect, where their roles are automated away without an equivalent expansion of middle-skill opportunities. Low-skill service jobs that require physical presence and human empathy, such as caregiving and hairdressing, may be more resilient to automation in the short term, while high-skill knowledge workers leverage AI to amplify their output. The result, some economists warn, could be a labour market polarised between a small, highly compensated cognitive elite and a large pool of low-wage service workers, with little room for the middle ground that has historically underpinned a broad middle class.
Paragraph F
Policymakers are beginning to grapple with these challenges. Several governments have introduced initiatives to reskill workers whose occupations are at risk, recognising that lifelong learning and vocational retraining will become essential features of modern labour markets. Some economists have proposed a universal basic income (UBI) as a mechanism for redistributing AI-generated wealth, though the financial feasibility and social implications of such a policy remain hotly debated. Meanwhile, technology companies argue that the solution lies in expanding access to STEM education and digital skills training from an early age, ensuring that future generations are equipped to work alongside, rather than be displaced by, intelligent machines.
Paragraph G
The historical precedent offers limited comfort. The First Industrial Revolution caused profound social dislocation before the benefits of mechanisation became broadly shared over several generations. Whether the AI revolution will follow a similar trajectory — painful disruption followed by widespread prosperity — or whether it will instead entrench inequality in ways that previous technological transitions did not, remains one of the defining economic questions of the twenty-first century.
設問
Questions 1–6: TRUE / FALSE / NOT GIVEN
パッセージの情報と一致するものを TRUE、矛盾するものを FALSE、情報がないものを NOT GIVEN と答えなさい。
Question 1
The automation of routine factory tasks began only after AI became widely available.
正解: FALSE — "Factory robots have long replaced assembly-line workers" (Paragraph B) → AI以前から自動化は進行していた。
Question 2
AI systems are now capable of performing some tasks at a level comparable to experienced professionals.
正解: TRUE — "AI systems can now diagnose diseases with a level of accuracy that rivals experienced physicians" (Paragraph B)
Question 3
The 2013 Frey and Osborne study concluded that nearly half of US jobs faced a significant risk of automation.
正解: TRUE — "approximately 47 per cent of jobs in the United States were at high risk of automation" (Paragraph C) — "nearly half" = 約47%。
Question 4
All economists agree that the Frey and Osborne projections accurately predict the speed of job displacement.
正解: FALSE — "Critics of this research argue, however, that such projections overestimate the pace..." (Paragraph C) — 批判者がいる = 全員同意ではない。
Question 5
The "augmentation thesis" argues that AI will work alongside humans rather than completely replacing them.
正解: TRUE — "AI becomes a collaborative tool that augments human capabilities rather than substituting for them entirely" (Paragraph D)
Question 6
Universal basic income has already been adopted by a majority of governments as a response to AI-driven unemployment.
正解: NOT GIVEN — "Some economists have proposed a UBI... though... remain hotly debated" (Paragraph F) — 提案段階であり、大多数の政府が採用済みとは書かれていない。
Questions 7–10: Multiple Choice
最も適切な選択肢を A / B / C / D から1つ選びなさい。
Question 7
According to the passage, what is considered distinctive about AI compared to previous waves of automation?
正解: B — "threatens not just manual labour but cognitive tasks that were previously considered the exclusive domain of human intelligence" (Paragraph A)
Question 8
According to the passage, which workers are described as most vulnerable to the "hollowing out" effect?
正解: C — "Workers in middle-skill occupations — those involving routine cognitive tasks... — face a ‘hollowing out’ effect" (Paragraph E)
Question 9
The word "augments" in paragraph 4 is closest in meaning to:
正解: C — enhances — "augments human capabilities rather than substituting for them" → replace(代替)の反対なので enhance(増強)が正解。
Question 10
What does the author suggest is uncertain about the AI revolution?
正解: B — "Whether the AI revolution will follow a similar trajectory — painful disruption followed by widespread prosperity — or whether it will instead entrench inequality... remains one of the defining economic questions" (Paragraph G)
Questions 11–12: Short Answer(3語以内)
パッセージから3語以内で答えなさい。
Question 11
What term does the passage use to describe the reduction in middle-skill occupations caused by automation?
正解: hollowing out — "face a 'hollowing out' effect" (Paragraph E)
Question 12
According to proponents of the augmentation thesis, what did the invention of the spreadsheet ultimately create, despite eliminating bookkeeping roles?
正解: financial analyst — "creating the profession of financial analyst" (Paragraph D)
