This is a speaking and listening exercise. What you have to do is simulate a phone conversation with your friend Federico.
For that you need to read the guide that they give you for the dialogue and then listen to the audio, finally answer the part of the dialogue that corresponds to you.

This is the guide for the dialogue:

**You**: Answer the phone.

**Federico**: (He says hi and asks how you are)

**You**: Say hi.

**Federico**: (He tells you something and asks you something)

**You**: Answer and ask him what he is going to do today.

**Federico**: (He answers you)

**You**: Tell him what you want to do.

**Federico**: (He asks you and invites you again)

**You**: Answer and explain why.

**Federico**: (He says good bye.)

**You**: Say goodbye and hang up.
