Well to me... I think this question is just logic because during the day, we use more energy but when we sleep at night we are not moving around as much as we are in our sleep.... Unless you sleep walk :p but once Dennis woke up, his hart started to work hard again from a long period of time of not pumping blood as to when we are walking and going about.

This doesn't answer your question but this is specific evidence on what the answer choice could be :)
