Task: Question Answering
Input (English): I was babysitting today and I got puked on , literally . It was like a moment from a slapstick comedy , you know , the one where the too - adorable - for - words toddler spews his mashed banana shit all over the unsuspecting babysitter's face . Yes , I had to go home and change ... yes , I should have charged them extra : PWhen I got home , I went straight over to Ankit's house . I hadn't seen him much lately , so I'll admit I was pretty eager to go over there . 
Question: What could have caused the baby to puke on the babysitter ?
Output (English): She fed him too much mashed bananas .
