Question

Which possible outcome below would not have supported the hypothesis?

if generation 3 had 33% of all three birds

if each bird ate only one type of food and not the other two

if generation 3 had flock distributions similar to those shown in the graph below
2 pie charts are shown. The first is labeled Three Foods with about half representing Flock X, about 33 percent being Flock Y, and 20 percent being Flock Z. The second is labeled Two foods with the same chart specifications.

Answer 1

The outcome that would not have supported the hypothesis is the one showing generation 3 with the same flock distributions in the "Three Foods" and "Two Foods" pie charts (i.e., no change in percentages between the two conditions).

Why: the hypothesis predicts that changing the available foods will change which birds are favored, so identical distributions across the two food conditions would show no effect and therefore fail to support the hypothesis.
