Read the passage carefully and then answer the following question. Researchers at a major university are testing a new drug to lower cholesterol, called Choless. They started the study by testing mice. Once they received the proper FDA clearances, they began trials on humans. They began testing on males, whose ages ranged between 30 and 60 years old. The researchers split the participants into two groups. Group A was given Choless, while Group B was given placebos. A placebo is completely harmless and looks exactly like Choless, but it contains no active medicine. None of the participants knew whether they were taking Choless or the placebo. The participants were to eat a diet low in saturated fats, and high in protein and fiber. Each participant's cholesterol levels were tested and recorded every week. Based on the passage above, determine each part of the experiment: subject: control: constant: independent variable: dependent variable:
