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.

Example Input: Context: 'Hey!  I hope you're having a good week and staying well.  So we are negotiating on supplies! 🙂' 'Yes. Hoping we can make a good deal.' 'Me too!  I'm hoping for two food items and one water.  I'm diabetic so if my blood sugar drops, I may need the extra carbs.  And water because water is important! 🙂 '
Utterance: 'I prefer two water and one food. I can understand why you need the extra food items. I'm not much of a snacker but do drink a lot of water all the time. Keeps me from eating more!🙂'
Example Output: Yes

Example Input: Context: 'Okay. I'm not especially worried about food. What's your lowest priority?' 'I have enough food too. Can I take 2 water, 1 firewood and 2 food?' 'How about two water, 1 firewood and 1 food, since we both value water the most?'
Utterance: 'Is that what you want or what you are offering?'
Example Output: No

Example Input: Context: 'I'm also going camping with my two children and 2 of my nephews  How would you like to divide the supplies?' 'Well what do you need the most of?' 'I need the most firewood due to a congenital issue that results in us having poor blood circulation to our extremities, thus making them susceptible to frostbite in the cold!'
Utterance: 'Oh dear, that sounds serious!  Well I need food the most because my children eat sooo much and I don't think I packed enough.  How about I'll give you all my firewood in exchange for all your food?'
Example Output:
No
