Task: Question Answering
Input (English): Every night I must put my son to bed. His name is Alex, and we have the same routine we do each and every night. Last night, we started our bedtime routine by taking a bath. Alex played with his bath toys, and splashed around in the bubbles. He then got dried off and put on his pajamas. Last night he wore his favorite pajamas with Lightning McQueen from the movie "Cars". We went into the bathroom and brushed our teeth, Alex used his green Crayola crayon toothbrush, and got his teeth nice and clean. We then read a bedtime story, last night was Goodnight Fish, which was a book he got when he and his grandparents went to visit the aquarium. After that, he got tucked into his crib, with his favorite blanket, and his favorite stuffed animals: a lamb and a penguin. We sang "Twinkle, Twinkle Little Star", and turned off the lights. Like each night, it was a good night. 
Question: who took the child to bed?
Output (English): The parent.
