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 uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.

Input: Consider Input: Context: 'I'd be willing to give you all my firewood if you could give me all the water.' 'I do need at least one extra water bottle in case the fire goes out of control, but I am willing to forgo any food as I can forage for food.' 'Alright. Thanks. I only ask for so much of the water because I am overweight and I know while camping I'll work up a huge sweat.'
Utterance: 'Great, that sounds good to me, are you okay with keeping all the food or would 3 be too much?'

Output: Yes

Output: Yes
