Task: Question Answering
Input (English): Passage: After I finished eating dinner , I began to feel very , very sleepy . Before I go to bed , though , I have to brush my teeth . I walked up to the bathroom , grabbed my toothbrush from the shelf on the wall , and ran it quickly under cold water . First , I opened my mouth wide and ran the brush along my bottom teeth , humming to myself while I did so . Once the tops of the bottoms of my teeth were cleaned , I made sure to reach my brush around to the back of my teeth and scrubbed those until they were clean , too . Then it was time for the top of my teeth , repeating this process on top until I am satisfied . Sometimes , I need to add a little more toothpaste to my brush , and then I clamp my teeth shut and begin to scrub my teeth , moving the brush in small circles all over . I spit out all the extra foamy toothpaste and rinse my mouth until it is clean . Question: What did they start doing to the teeth? Option1: cleaning Option2: painting
Output (English): cleaning
