Task: Question Answering
Input (English): I recently graduated from college and decided to throw a party at my house to celebrate. I wanted to invite my classmates who graduated along with me. I made a list of everyone that I wanted to invite. Then, I went to the store to buy the invitations. I looked through the rows of cards until I found the graduation invitation section, with one section specifically for college graduation. I looked through the selection of cards there until I found a few that I liked. Deciding that I wanted to send a variety of different cards to my friends, I bought a few of each card until I had enough cards for everyone. Then, I went to the cashier, purchased the cards, and went home. Once I got home, I wrote messages in each of the cards along with the names of each person that I was inviting. Then, I mailed the cards. 
Question: Who wrote all the invitations?
