This week we learned about taste . I was lucky enough to be a volunteer and learned a lot about the human taste buds and my own abilities to distinguish between flavors . In the experiment I tested my ability to distinguish between different cubes of food . One was a potato and one was an apple .

Question: What may have happened if I did not volunteer ?
Answer: None of the above choices .I would not have found out that I have taste buds .I would not have found out how taste buds work .I would not have found out the difference between a potato and an apple .
