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: 'Would you be willing to trade a piece of firewood for an extra water bottle? That will save me some time from chopping down extra wood.' 'no, best i can offer is i get 3 firewood, 2 water and 1 food' 'No thanks.☹️'
Utterance: 'ok, last deal, i get 3 firewood, 1 water and 1 food'
Example Output: No

Example Input: Context: 'Hi! I like to hike so I really need more water. Could I take 2 packages of water and 1 of food and 2 of firewood?' 'I am ok with the water, i just would like one water and one food, but i would appreciate two firewoods, i get cold at night '
Utterance: 'We both sound pretty reasonable! So you think you need 2 firewood?'
Example Output: No

Example Input: Context: 'Ok me too! I am concerned the most with firewood as it is the basis for my camping activities: campfire, story telling, and producing heat. ' 'OK so how about you take 2 firewoods and 1 food' 'That works for me. May I have two waters since I have more of a need of water'
Utterance: 'That works for me since I have the filter!'
Example Output:
Yes
