💡 Detailed Explanation
Translation of Script:
- Narrator: A man and a woman are talking. Why did the man miss school yesterday?
- Woman: Sato-kun, you were absent yesterday. Did you catch a cold?
- Man: Actually, yes, I caught a cold and had a fever. But my head was fine.
- Woman: I see. Are you okay now?
- Man: Yes, I slept a lot yesterday, so I'm completely fine today.
- Woman: That's good.
Explanation of Answer:
- The woman asks if he missed school because he caught a cold (風邪をひいたの？).
- The man confirms: 'Actually, yes, I caught a cold and had a fever' (実は風邪をひいて、熱が出たんだ).
- He also adds that his head did not hurt (頭は痛くなかったけど), ruling out the 'headache' choice.
- Therefore, the reason is catching a cold. Choice 1 (風邪を ひいたから) is correct.
