You are presented with the quiz "Weathering means eroding rocks down into what pieces of minerals?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "weathering means breaking down rocks from larger whole into smaller pieces by weather" and "when rocks are weathered and eroded they break down into smaller pieces of rocks and minerals". 

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