Task: Wrong Candidate Generation
Input (English): Context: So we walked a little and came across the Gondola ride . I did n't notice there were both swinging and non swinging gondolas until we got right up front in the line . We had to wait while a gondola was cleaned since someone had thrown up inside . I wanted to chicken out at the last minute but the ride * looked * ok and I figured it must have been a little kid who 'd eaten too much junk food so I got on despite the nagging warnings in my head . 
Question: Why may someone have thrown up inside the narrator 's gondola ? 
Correct Answer: The narrator 's gondola was a swinging one .
Output (English): The narrator was in a stationary gondola .
