conclude that hummingbirds prefer white flowers write a report about the kinds of flowers in the garden observe hummingbirds at flowers and record the flower color research the number of different hummingbirds that live in the garden
I gave my students this multiple choice question: Students visited a garden to observe hummingbirds. They wanted to find out if hummingbirds were more likely to visit colored flowers or white flowers. Which should the students do first for this investigation?

Only one answer is correct among these 4 choices:
- conclude that hummingbirds prefer white flowers
- write a report about the kinds of flowers in the garden
- observe hummingbirds at flowers and record the flower color
- research the number of different hummingbirds that live in the garden

Could you tell me which one is correct?

observe hummingbirds at flowers and record the flower color
