User: I want to see an IMAX movie tonight. Are there any movies in theaters tonight?
Assistant: Actually there are quite a few out tonight. Would you like me to check IMAX presentations that are scheduled?
User: Yes, please.
Assistant: Sure. I see that there is a showing of the movie 1917. It is an 3D viewing.
User: Is there any IMAX showings scheduled around 3:00pm?
Assistant: Yes. The showing closest to 3:00pm is the 4:45pm showing and that is a IMAX showing.
User: No. That won't work. I need a movie after 5:30pm. Hopefully an IMAX showing. Closer to 9pm.
Assistant: I see that there is a showing of 1917 scheduled at 9pm and this is the last showing for the night.
