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.

Example Input: Context: 'Hello! I'll be camping soon and need to get my hands on some supplies. The food is what I need the most.' 'I'm glad you are joining the camp! I will be bringing my girl scout troop for some badge earning opportunities.'
Utterance: 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.'
Example Output: Yes

Example Input: Context: 'Hi! I'm super excited to go camping with my family as a great way to vacation due to Covid19. My kid is so restless from being cooped up in the house all the time. Are you planning on going camping too?' 'I am! It is the perfect way to get away and still manage to social distance! I am worried about having enough water though, are you short on any supplies?'
Utterance: 'I think I'm good. I'm not 100% sure. My husband likes to do adventures on the fly. He got these water filter straw thingies from Amazon and said that if we run out of the water I packed, that we can drink the water in the lake but I don't really trust the straws.'
Example Output: No

Example Input: Context: 'I am thinking I will want food most'
Utterance: 'Great! Food is not my priority but water and food is.'
Example Output:
No
