정답: B. 천둥

How to solve: The sentence describes a 'big sound from the sky'. Among the choices, '천둥' (thunder) refers to the sound, making it the most appropriate fit.

A — 번개 (lightning) is the light, not the sound.

B — 천둥 (thunder) is the loud sound that accompanies lightning.

C — 구름 (cloud) are visible in the sky but don't make a 'big sound'.

D — 비 (rain) is precipitation and doesn't directly refer to a 'big sound' in this context.

정답: C. 번개

How to solve: The sentence mentions a 'bright flash' ('번쩍') from the sky at night. '번개' (lightning) is the bright flash of light associated with a thunderstorm.

A — 바람 (wind) is air movement, not a bright flash.

B — 햇빛 (sunlight) occurs during the day, not '번쩍' at night.

C — 번개 (lightning) is the bright flash of light during a thunderstorm.

D — 무지개 (rainbow) appears after rain with sunlight, not as a flash.

정답: B. 천둥번개

How to solve: The sentence describes heavy rain and something that 'strikes' (치다). Among the choices, '천둥번개' (thunder and lightning) refers to both thunder and lightning, which commonly accompany heavy rain and are described with '치다' (e.g., 번개가 치다, 천둥이 치다).

A — 안개 (fog) is fog and does not involve striking or heavy rain in this context.

B — 천둥번개 (thunder and lightning) refers to thunder and lightning, which fit the description of '치기 시작했어요' and often accompany heavy rain.

C — 눈 (snow) is snow, which is different from rain and thunder/lightning.

D — 맑은 날씨 (clear weather) is the opposite of the situation described.

정답: B. 폭우

How to solve: The sentence describes conditions (trees falling, slippery roads) caused by '강풍' (strong wind) and a type of rain. '폭우' (heavy rain) is severe enough to cause such damage and conditions, more so than a light shower or drizzle.

A — 소나기 (shower) is a short, sudden shower, usually not causing trees to fall.

B — 폭우 (heavy rain) is very heavy rain, which, combined with strong winds, can indeed cause trees to fall and roads to become slippery.

C — 이슬비 (drizzle) is very light rain and would not cause such severe effects.

D — 맑은 하늘 (clear sky) means a clear sky, which is the opposite of a situation with rain and strong winds.

정답: B. 조심해야

How to solve: The sentence states that it's dangerous ('위험하니') when there's severe thunder and lightning. Therefore, one 'should be careful' (조심해야 합니다).

A — 웃어야 합니다 (should laugh) is inappropriate for a dangerous situation.

B — 조심해야 합니다 (should be careful) is the correct action to take when facing danger like severe thunderstorms.

C — 달려야 합니다 (should run) might be dangerous and is not the general safety advice for a thunderstorm.

D — 소리쳐야 합니다 (should shout) is not a general safety measure for thunderstorms.
