Task: Question Answering
Input (English): On a bright, sunny Monday morning I put on some light clothes and headed outside to mow my lawn. I opened the garage door, put on my sunglasses, and grabbed a bottle of cold water. I gassed up the lawn mower with my portable gas tank. I pushed the mower into the yard where I normally started to mow. I cranked to mower, and on the third try it started. I pushed the mower back and forth throughout my yard, creating straight and conformed lines. Once I had completely mowed the front of my yard, I turned the mower off and took long drinks of my water. I then pushed the mower to the backyard and started it up again. Making straight lines in the grass, I completed the backyard, as well. As I turned my mower off, a neighbor who was passing by waved and gave me a smile. I smiled back and continued to clean up and put my mower away. 
Question: What did they drink while mowing?
Output (English): Water
