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: 'I'd be fine with taking less food.  So, I would get 3 firewood, 1 food, and 0 water.  Is that correct?' 'And I would get 0 firewood, 2 food and 3 water. That seems right to me.' 'That'
Utterance: 'It looks like we have to continue this conversation beyond a certain point before we come to a deal, so - what is your most cherished camping memory?'
Example Output: No

Example Input: Context: 'Same here! Last time my daughter got dehydrated and it made her sick!' 'That sounds awful! 😮 Where are you going to be camping?' 'In Arizona, so I know it'll be hot. How about you? '
Utterance: 'Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.'
Example Output: Yes

Example Input: Context: 'Hi!  The weather is going to be a lot colder than I anticipated, so I need extra firewood.  Would you be willing to give some to me?'
Utterance: 'Sure, but I need 2 packs of firewood and 2 packs of food and water'
Example Output:
No
