Dialogue:

M: Where is Joan? She said she would be here at three. And now it's three-thirty. She must have missed the train.

W: I think so, but I hope she won't miss the next one. Otherwise, she should be late for the opening address of the conference.

Question: What's the woman worried about? 

- Joan may have taken a wrong train.

- Joan will miss the next conference.

- Joan may be late for the opening speech.


Joan may be late for the opening speech.
