四番。会社で、女の人と男の人が話しています。女の人は、この後まず何をしますか。

The correct choice is Option 2: 'Update the list of participants.' The woman initially proposed calling the restaurant immediately, but when the man suggested updating the list first, she agreed: '私が今すぐリストを更新してしまうわ。そのあと、店に電話を入れるね' (I will update the list right now. After that, I will call the restaurant). Thus, updating the list (Option 2) is the immediate first action she takes, and calling the restaurant (Option 1) happens second.
