Choose the hypothesis for the controlled experiment that answers the question:
“Does feeding animals a high-protein diet build muscle?”
Feeding animals, a high-protein diet will do more harm than good.
If I eat a high-protein diet, then I will spend too much money. High-protein diets are too expensive.
If animals are fed a high-protein diet, then it will not cause them to build muscle.
High-protein diets are not healthy for animals.
