You are presented with the quiz "What found in a place shows that animal or plant used to live in that place?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "if fossils of an animal or plant are found in a place then that animal or plant used to live in that place" and "fossils are the remains of prehistoric life". 

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


 

 remains
