generate response: I would be travelling on Monday and heading TO Stevenage FROM Cambridge. I'm sorry, I stated that wrong the first time.. Intent: find_train. Slots: train-day=monday, train-departure=cambridge, train-destination=stevenage, train-leaveat=10:45
Response: THere is a train that leaves at 11:21 and then trains that leave every two hours after that. Does one of those sound best?
