TOPIK Practice – TOPIK I 어휘 [어휘] 1–5 (7/22/2026) – ai bubble

정답: A. 거품

How to solve: The sentence describes something growing rapidly in relation to AI. The context of 'AI bubble' suggests an excessive, unsustainable growth. '거품' (bubble) fits this context.

A — '거품' means 'bubble'. It fits the context of an 'AI bubble' where value is inflated beyond its fundamental worth.

B — '기술' means 'technology'. While AI involves technology, 'technology growing' doesn't fit the 'excessive growth' nuance as well as 'bubble', which implies a potential collapse.

C — '시장' means 'market'. The market can grow, but the sentence implies something potentially unsustainable or problematic, which 'bubble' captures better.

D — '발전' means 'development' or 'progress'. AI's development is growing, but the sentence suggests a negative connotation or warning about excessive growth, which 'bubble' provides.

정답: C. 투자

How to solve: The sentence talks about the market overheating ('과열') due to something being 'too much' in the AI industry. Excessive '투자' (investment) is a common cause of market overheating and bubble formation.

A — '교육' means 'education'. Too much education doesn't directly lead to market overheating in a financial sense.

B — '관심' means 'interest'. While strong interest is related, it's the 'investment' that directly fuels market overheating and price speculation.

C — '투자' means 'investment'. Excessive investment leads to market overheating and can create a bubble. This fits the context perfectly.

D — '생산' means 'production'. Too much production could lead to oversupply, but '과열' (overheat) in market terms is more specifically related to excessive capital inflow and speculation.

정답: D. 급성장

How to solve: The sentence asks what AI technology has shown in recent years. The concept of an 'AI bubble' implies a period of significant and rapid growth before a potential correction. '급성장' (rapid growth) is the most fitting positive trend among the options.

A — '하락' means 'decline' or 'fall'. AI technology has clearly not been declining.

B — '정체' means 'stagnation'. AI technology is currently experiencing rapid advancements, not stagnation.

C — '감소' means 'decrease'. This is the opposite of the observed trend for AI technology.

D — '급성장' means 'rapid growth'. This accurately describes the recent trajectory of AI technology and is a fundamental characteristic leading to a bubble.

정답: B. 실제

How to solve: The sentence states that some experts warn AI company stock prices are 'too high' compared to a certain 'value'. In the context of a bubble, stock prices are often inflated beyond their '실제' (actual/real) value.

A — '미래' means 'future'. While future potential affects valuation, the concern in a bubble is often that current prices exceed the present actual value or even realistic future value.

B — '실제' means 'actual' or 'real'. This fits the context of a bubble where prices are speculated to be higher than the company's intrinsic or actual value.

C — '감성' means 'emotion' or 'sensibility'. This is not relevant to objective stock valuation.

D — '문화' means 'culture'. This term is completely unrelated to stock valuation or market analysis.

정답: C. 거품

How to solve: The phrase '___이/가 터지다' means '___ bursts'. In the context of 'AI bubble', it refers to the bursting of the '거품' (bubble), which would lead to negative consequences like companies facing difficulties.

A — '시장' means 'market'. A market doesn't 'burst' in this metaphorical sense; rather, a bubble within a market bursts.

B — '기술' means 'technology'. Technology does not 'burst'.

C — '거품' means 'bubble'. A bubble 'bursts' ('거품이 터지다'), leading to a market correction or collapse, which perfectly fits the sentence's implication of companies facing difficulties.

D — '발전' means 'development' or 'progress'. Development does not 'burst'.
