In the health conscious city of Vaudeville, people use two main types of transport: bicycles and walking. Biking slowly, a person can reach most destinations in 20-40 minutes while burning around 250-400 calories. Biking quickly to the same destination takes about 10 to 20 minutes and burns the same number of calories. Walking slowly to those destinations takes 40 to 80 minutes while walking quickly takes 30 to 60 minutes. Both walking activities burn the same number of calories as biking. Also, it was found that the longer a person spends exercising the better it is for the heart.

If the statements above are correct, they most strongly support which of the following?

A. Biking promotes the development of muscles more than walking does, regardless of the time spent on both types of exercise.

B. On average, fast walking is healthier than slow biking when going the same distance even though both activities burn the same number of calories.

C. Walking fast has more extra benefits, apart from calorie burning, than slower walking.

D. Biking for longer but at a slower pace burns more calories than biking for shorter periods of time at a faster pace over the same distance.

E. The promotion of better health must include exercise that is also good for the heart.
