Task: Question Answering
Input (English): Passage: I had a break between my classes and was feeling a little hungry . I walked to the library and went into the basement where the vending machines were . I did not want a whole meal , so a vending machine snack seemed like a good choice . After looking through my options I decided that some animal crackers would do the trick and help me feel full and alert before my next class . I put my seventy five cents into the coin slot and punch in A-4 , which was the number under the animal crackers that I wanted . As soon as I did the stop on the animal crackers dropped just long enough for one pack of animal crackers to fall down . Off I went , happy to have found a vending machine and buy the animal crackers that I desired . Question: When did they push back the lid on the retrieval drawer?
