You are presented with the quiz "The device used by biologists to make small things appear bigger was invented by whom?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "microscope is used to see small things by biologists by making them appear bigger" and "many people think that Leeuwenhoek invented the microscope". 

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


 

     Leeuwenhoek
