Task: Question Answering
Input (English): Passage: I live on a large property of apartments that has several nice activities for it 's residents to enjoy . One of my favorite activities is tennis ! I own 3 different rackets , all different colors , and like to experiment with each one . My neighbor Bill , who enjoys tennis as much as me , usually meets me on Tuesday afternoons for a few quick matches . We start by warming up before we get into playing with each other . The ball goes back and forth until someone misses a shot , or the ball goes out of bounds . The person who served gets the points and the person returning gets the ball to serve if they win . Bill has been playing for about 10 years longer than me , so he usually ends up winning . Question: who do they serve to? Option1: Each other, alternating. Option2: The other residents.
Output (English): Each other, alternating.
