Shelly wants to know if hummingbirds prefer honey, sugar, or corn syrup. she creates three solutions of equal sweetness. one solution is made of honey and water; the second is sugar water, and the third is corn syrup and water. she places three hummingbird feeders side-by-side outside a window. to make sure she could tell them apart, she puts each solution in a different-colored feeder: one is red, one is yellow, and one is blue. shelly spent a day collecting data by sitting in the chair and recording her observations about how many hummingbirds came to each feeder, how long they stayed at each, and, when possible, if they returned to a feeder after tasting another. shelly's experiment will not give conclusive results. what is the most important reason why it will not?
