Task: Question Answering
Input (English): I wanted to send invitations to 25 people I hoped would come to a birthday party for my boyfriend. I drove to a store that sells different types of cards, including packages of invitations. There, I found some festive-looking cards that would be ideal for this purpose. I chose three packages holding 10 invitations each. I paid for them at a cashier's counter. After driving home, I filled out each invitation in ink with the necessary information and signed my name. Then I wrote out the envelopes by hand with each person's name and address. I had to use my address book to find the information or else I needed to look it up online if I didn't have the details. When this task was complete, I placed a postage stamp in the upper-right corner of each envelope, then licked the adhesive on each envelope before pressing the flap down to seal it. The final step was to bring all the envelopes to the post office the next day and place them in the box for outgoing mail.
Output (English): who signed all the invitations?
