Task: Wrong Candidate Generation
Input (English): Context: However , I was already having a horrible day , and to top it off , some little spawn of the devil threw a STINK BOMB in my classroom right before fourth period ! Well , that just pushed me over the edge . I had to spend the rest of the day going from classroom to classroom and using the classroom of whichever teacher had prep that period . This meant that I ( and my students ) had to carry around all my books , materials , etc . 
Question: Why did I have to move from classroom to classroom ? 
Correct Answer: Because my classroom smelled really bad .
Output (English): Because another teacher was using my classroom .
