You are presented with the quiz "Rabbits are what, so they cannot remove toxic material from their stomachs before it is absorbed?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "the vomiting reflex is used to remove toxic material from the stomach before it is absorbed" and "rabbits lack the vomiting reflex, and are physically almost incapable of regurgitation". 

So, what's the best answer to the question?


 

     incapable of regurgitation
