Question

Ablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing their dogs and the diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs.

When they write up their initial proposal, the instructor will probably ________.

Answer 1

When they write up their initial proposal, the instructor will probably state that the cannot compare a shepherd-mix dog with a bulldog. Since they are different races, the diet is not representative of the feature they want to measure.

In order to compare which diet results in bigger, healthier and faster growing dogs, they should have the same dog.
