Final answer:

The change in temperature from 18°F to -22°F is a 40°F decrease, calculated by subtracting the lower temperature from the higher temperature.

Step-by-step explanation:

The change in temperature when going from a section that is 18°F to a section that is -22°F can be found by subtracting the lower temperature from the higher temperature. The calculation would be 18°F - (-22°F), which equals 18°F + 22°F because subtracting a negative number is the same as adding a positive number. The result is a temperature change of 40°F. Therefore, the correct answer is C. 40°F. In this case, the temperature change is independent of the direction, so we don't need to consider negative or positive signs.

Therefore, the correct answer is A. -40°F.
