💡 Detailed Explanation
Translation of Script:
- Narrator: A man and a woman are talking. How many hours did the woman study yesterday?
- Man: Yamada-san, did you study a lot yesterday for the exam?
- Woman: Yes. I usually only study for 1 hour, but yesterday I studied for 3 hours.
- Man: Wow, 3 hours! That's a lot. I only studied for 2 hours.
- Woman: We both worked hard.
Explanation of Answer:
- The woman states her study time clearly:
- Normal day: 1 hour (いつもは１時間).
- Yesterday: 3 hours (昨日は３時間).
- The man also mentions his own time (2 hours - ２時間) to serve as a distractor.
- The question is about the *woman's* study time yesterday. Therefore, she studied for 3 hours. Choice 3 (３時間) is correct.
