A) Sally hypothesizes that the flap rate depends upon the bird's weight and constructs a mathematical model describing her theory.
B) Sally hypothesizes that the flap rate depends upon the bird's weight. She then designs an experiment to measure flap rate as a set of birds grow and reports her results.
C) Sally observes dozens of species of birds and records their flap rates and other characteristics. She then measures which characteristics correlate best with flap rate and reports her findings.
D) Sally observes dozens of species of birds and finds the highest flap rate.
