The graph below is from an experiment where total light exposure was adjusted for three groups of rats. Each group had 12 rats and each group was exposed to different amounts of light versus dark in a 24-hour period for three months. Food consumption was measured in each group following each 24-hour period. Food pellets are reported as means per group for three months. (Note: All rats used in the experiment were the same age and breed. All were fed the same kind of food pellets.)

Question

The graph below is from an experiment where total light exposure was adjusted for three groups of rats. Each group had 12 rats and each group was exposed to different amounts of  light versus dark in a 24-hour period for three months. Food  consumption was measured in each group following each 24-hour period. Food pellets are reported as means per group for three months. (Note: All rats used in the experiment were the same age and breed. All were fed the same kind of food pellets.)

Light schedules affect the appetites of rats.
Rats eat more when they are exposed to more light.
The appetites of rats are unrelated to light schedule.
Rats eat more when they are exposed to higher temperatures.

GPT-4o mini · Answer

Based on the description of the experiment and the options provided, the most reasonable inference from the graph would be:

Light schedules affect the appetites of rats.

This conclusion aligns with the idea that the different light versus dark conditions might impact the rats' feeding behavior, which is what the experiment appears to be investigating. The other options either misinterpret the relationship or introduce unrelated variables (like temperature) that are not indicated in the provided information.
