Task: Question Answering
Input (English): Background Paragraph: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. 
Story: Two neighboring counties, Brown and Green county, had different weather patterns occur last month. The weather in Brown county was quite stable, but green county experienced atmospheric convection and other related phenomena. 
Question: Which county had less parcel-environment instability?
Output (English): Brown.
