You will be given a definition of a task first, then some input of the task.
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.

Context: 'I will provide you the food, but I am asking only one for my people.' 'I am giving you all the water,  how come you need the food? ' 'The main reason is to prevent us from cold.  Please provide three wood and three water.  If this is okay, then I will provide you three food.'
Utterance: 'Food doesn't prevent cold. Thank you for giving me all the food but I need 1 wood to cook the additional food. You still end up with more items in the  end  '
Output:
Yes
