Task: Question Answering
Input (English): My daughter's 10th birthday was coming up in about a month. My husband and I had decided to throw her a party because she was so excited to turn 10 years old. We planned some entertainment for the party and agreed on the food and treats to be served. Then it was time to invite all of her friends to the party. We made a list of her friends with her help. We then looked online for invitations and found a great selection. We let our daughter pick her favorite and ordered 30 of them. When the invitations came we filled out the names for each then addressed the envelopes with only names so that she could hand the invitations out at school. Each invitation explained what the party was for, when it would be, and what to bring and expect. She took the invitations to school the next day and handed them to all of her friends, barely able to contain her excitement. The party was a hit. 
Question: Who was the party for?
Output (English): their 10 year old daughter
