An experiment was performed with 30 lab rats exposed to three different diets (10 rats per diet). Researchers fed the rats with the same weight of food and tested them in trials with an exercise wheel three hours after food intake every day. The sugar content in every diet is presented in the table below.

Daniel was jogging on the West River Trail in Oklahoma City in a late fall morning when the Sun started to rise above the horizon. It was a cold morning and he noticed that many grasshoppers on the asphalt surface of the trail did not move even when he touched them. It was a very sunny and windless day and Daniel started to get sweaty along with the passing of time. Later in that morning he saw many smaller grasshoppers starting to jump around on the asphalt surface but larger ones still did not move when touched. The larger grasshoppers finally started to jump around during the afternoon hours.
