In this task, you are given a conversation between a flight agent and the customer. You are given 4 options and you need to select the goal of the conversation. It is provided as part of customer's context, which has to be one of the following: `book`: Make a new reservation, `cancel`: Cancel an existing reservation, `no_flight`: No flight found for the customer's preference, `no_reservation`: No reservation / No change / No cancellation was made in the conversation, mostly enquiring details

Let me give you an example: customer: Hi. 
 agent: Hello. How can I help you? 
 customer: I would like to change my existing reservation as my plan to go for a holiday trip got postponed. Can you please help me with this? 
 agent: Sure, may I know your name please? 
 customer: My name is Anthony Phillips. 
 agent: Please wait a moment. 
 customer: Sure. 
 agent: Unfortunately there is no reservation found with your given name. 
 customer: Not a problem, thank you for checking. 
 agent: Thank you for choosing us.
The answer to this example can be: no_reservation
Here is why: Here the customer has not asked for any booking, he just wanted to update his already booked flight, so the status would be no_reservation

OK. solve this:
customer: Hello, I am Rachel King. 
 agent: Hello, How can I be your helping hand the day? 
 customer: Due to bad weather condition, I want to cancel my reservation ticket. Can you help me out in this? 
 agent: Sure, I am here to help you. Please wait for a minute, I will be right back. 
 customer: Sure. 
 agent: Thanks for being patient. We did not find any reservation with your name to cancel the reservation. 
 customer: It's ok, not a problem. 
 agent: Thank you for contacting us. 
 customer: Thank you for your information.
Answer:
no_reservation
