Which of the following is not a baseline activity? reading sitting in class paddling a canoe using a calculator

The correct answer is C. Paddling a canoe

Explanation:

An activity is classified as a baseline activity if it does not require a great effort, which means it is a light-intensity activity. Examples of baseline activities include most daily activities such as walking slowly, sitting in class, watching a movie, etc. According to this, the one that is not a baseline activity is paddling a canoe because different from reading, sitting in class or using a calculator, this activity requires a considerable effort and it is a moderate or high-intensity activity and therefore it cannot be classified as a baseline activity.
