Task: Negotiation Strategy Detection
Input (English): Context: 'My primary concerns are staying hydrated, I have been feeling sick and throwing up from being so high up in the mountains. ' 'Oh, so sorry to hear that.  I can understand why water would be important to you.  I am worried about being too cold at night. My sleeping bag is not rated well for cold weather (I packed the wring one).' 'Oh I understand that for sure. I am not used to the cold weather either which is not helping. Would you be interested in a trade for water in exchange for firewood? '
Utterance: 'Well, I am worried about staying hydrated as well.'
Output (English): Yes
