Increasing the electrical load carried on a transmission line increases the line’s temperature, and too great a load will cause the line to exceed its maximum operating temperature. The line’s temperature is also affected by wind speed and direction: Strong winds cool the line more than light winds, and wind blowing across a line cools it more than does wind blowing parallel to it.

Summary
Increasing an electrical load on a transmission line causes the line’s temperature to increase. Too big of a load causes the line to exceed its maximum operating temperature. However, the temperature is also affected with wind speed and direction. Strong winds cool the line more than light winds, and winds blowing across a line cools the line more than winds blowing parallel to it.

Strongly Supported Conclusions
When wind speed increases, the load a transmission line can carry without exceeding maximum operating temperature also increases.

A
Electrical utility companies typically increase the electrical load on their transmission lines on days on which the wind has a strong cooling effect.
This answer is unsupported. We don’t know how electrical utility companies usually operate. We can assume this is true, but we don’t know it for a fact based on the stimulus.
B
Transmission lines that run parallel to the prevailing winds can generally carry greater electrical loads than otherwise identical lines at a right angle to the prevailing winds.
This answer is anti-supported. Based on the stimulus, the winds blowing at a right angle would cool a line more than winds blowing parallel to the line.
C
The electrical load that a transmission line can carry without reaching its maximum operating temperature increases when the wind speed increases.
This answer is strongly supported. Load capacity is correlated with the temperature of a transmission line. The more external factors like wind cool the line, the greater load capacity the line has.
D
Air temperature has less effect on the temperature of a transmission line than wind speed does.
This answer is unsupported. We don’t know how the surrounding air temperature could effect a transmission line’s temperature.
E
The maximum operating temperature of a transmission line is greater on windy days than on calm days.
This answer is unsupported. We don’t know whether the maximum operating temperature for a transmission line ever changes.
