The woman initially expressed concern about the long core time, expecting more freedom. The man explained that the human resources department stated the reason was 'to smooth coordination between departments,' especially because many meetings are concentrated in the early afternoon, and they want everyone to be in the office during that time. The woman then says, 'なるほど、部署間の連携をスムーズにするため、ですか' (I see, it's to smooth coordination between departments, isn't it?), confirming her understanding. Therefore, the correct answer is 'To smooth coordination between departments.'
