Recently, beekeepers have noticed an alarming and sudden disappearance of honeybees from their hives. Some beekeepers and environmentalists worry that crops genetically engineered to contain the gene for the Bt insecticidal toxin may be killing the bees. Which of these experiments tests the hypothesis that Bt is killing the bees?

collecting hundreds of bees; half of the bees world be kept in a facility with plants genetically engineered to contain the gene for Bt toxin, while the other half would be kept in a facility with plants not genetically engineered to contain the gene for Bt toxin. The survival rate for both sets of bees would be calculated and compared.
