Which of the following assumptions of the given statement is valid?

Statement:

They will be leaving in an hour, but now I have to remember my lessons, so I won't be able to say goodbye to them.

Assumptions:

I. The lessons will take more than an hour to complete.

II. People leaving are not expecting me to say goodbye to them before departure.

Solution

Let's analyze the assumptions based on the given statement: Statement: "They will be leaving in an hour, but now I have to remember my lessons, so I won't be able to say goodbye to them." Assumptions: I. The lessons will take more than an hour to complete. II. People leaving are not expecting me to say goodbye to them before departure. Now, let's evaluate each assumption: I. The statement doesn't explicitly mention the duration of the lessons, so we can't definitively say whether they will take more than an hour. It's possible that the lessons will take more than an hour, but it's also possible that they won't. Therefore, assumption I is not necessarily valid. II. The statement implies that the speaker won't be able to say goodbye to the people leaving because they need to remember their lessons. This suggests that saying goodbye is not possible due to the speaker's own constraints, not because the people leaving don't expect it. So, assumption II is valid. Therefore, the correct answer is: Only assumption II is valid. Hence, option 1.
