This I have discovered has a major disadvantage . ( You may wish to skip the rest of this post , by the way . ) Basically , because the poo does n't go into water but just sits there , it has time to make the room smells more before you flush . On the other hand though , there is no possibility of splashback .
According to the above context, choose the best option to answer the following question.
Question: Why does the room smell so much .
Options:
- Because something was left to rot in the room .
 - Because the lack of water means the poo is exposed .
 - None of the above choices .
 - Because something died in the room .


Because the lack of water means the poo is exposed .
