Teacher: The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Context: 
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Solution: No
Reason: The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.

Now, solve this instance: Context: 'Hi, how are you, ready for the big camping trip?' 'Yes I am. I'm actually already at the camp and came across some homeless people who could really use all the food they can get.'
Utterance: 'Wow, ok. I'd can give you some food, I'd like to have a little extra food and water as we have a larger group going. '
Student:
No
