What factor increases the rate of heat transfer from one side of a structure to the other?

Humidity level
Insulation material
Temperature differential
Wind speed

The correct answer is: Temperature differential

Heat transfer occurs when there is a difference in temperature between two objects or areas. Therefore, it makes sense that the temperature differential would play a significant factor in increasing the rate of heat transfer from one side of a structure to the other. As for the other options, humidity level and insulation material may affect the overall energy efficiency of a structure, but they do not directly impact the rate of heat transfer. Wind speed may affect the rate of heat transfer on the exterior of a structure, but it is not a factor that applies to all sides of the structure. Therefore, C is the most accurate and logical choice.
