Task: Question Answering
Input (English): On Saturday night, I decided to go bowling with four of my good friends.  When we got to the bowling alley, we paid the cashier.  Then we each got shoes to go bowling in and selected our bowling balls.  We had to try a few balls by picking them up to see how it felt when we held it.  After everyone had their shoes and their balls, we went to our assigned lane.  Once there, we had to set up the computer that keeps track of the scores by putting in our names.  When that was done, my friend Darren went first. He got a strike!  After Darren, Lori, Ann, and Jeff went.  I went last and got a gutter ball.  I got to go again and I knocked over five pins.  The computer calculated our scores and we went onto the next frame.  At the end, the computer tallied everyone's final scores.
Output (English): What day did they go bowling?
