Read the following paragraph, then answer the question: A scientist conducted an experiment to determine the effect of environment on the fur color of Himalayan rabbit. The Himalayan rabbit typically has a white coat except for its colder nose, feet, tail and ears, which are black. The scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on one rabbit (A) the other rabbit (B) had nothing placed over the shaved area.

Which Rabbit in the experiment was the control? (A or B)

• Rabbit A (The rabbit with the ice on it's back)

• Rabbit B (The rabbit without the ice on it's back)
