Who will be the winner of the next lottery? What football team will win the next game? What is the amount of light needed to grow tomatoes? Which four types of bird feathers have the prettiest colors?
I gave my students this multiple choice question: Which question can most likely be determined through a scientific investigation?

Only one answer is correct among these 4 choices:
- Who will be the winner of the next lottery?
- What football team will win the next game?
- What is the amount of light needed to grow tomatoes?
- Which four types of bird feathers have the prettiest colors?

Could you tell me which one is correct?
