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: 'hello how are you' 'i'm good thank you, How are you doing today?' 'I am good, let's plan our camping trips. I am diabetes, so water is very important to me. what about you?'
Utterance: 'I need water too'
Example Output: No

Example Input: Context: 'Oh yeah, that's for sure. What camping item do you prioritize?' 'I'm going to need some extra wood because I'm somewhat injured and can't really gather more.' 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.'
Utterance: 'Yes, that's important. I don't need much.'
Example Output: Yes

Example Input: Context: 'Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?' 'That sounds fair, how much food do you feel you need? ' 'I would prefer 2 because it's really easy to underestimate how much I could need.'
Utterance: 'That's fine, I'll take 1. I think I have enough with what was originally given. '
Example Output:
Yes
