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 ?
Options: 
- Because my classroom smelled really bad .
 - Because I did n't have my own classroom .
 - Because they were spraying mine for bugs .
 - Because another teacher was using my classroom .


Because my classroom smelled really bad .
