A special program gets people to walk more and be healthy. Each day, people are asked to take 2,000 more steps. They can take the steps in a store or in a park—it does not matter. As long as people walk more, they will get exercise. They may not lose weight, but they will not gain weight either. Dr. Hill started the program. He tested it on many people. They did the additional walking and did not think it was too hard. They were able to keep doing it for a long time. Dr. Hill wants people all over America to try it. He says that it will make Americans much healthier. Select the word that best completes the following sentence:
People thought that the program was:
A. Unclear
B. simple

D. Fancy
