Read the passage below and answer the question that follows: Many cities are replacing conventional streetlights with smart LED lighting systems to reduce electricity consumption and maintenance costs. These smart lights use sensors to adjust brightness based on the presence of vehicles or pedestrians. However, critics argue that the transition might not significantly reduce energy consumption if the lights remain on throughout the night in areas with consistent traffic. Which of the following statements, if true, would strengthen or weaken the argument in the passage?
A. Several studies show that smart lighting systems have reduced electricity bills in cities by nearly 40%. (Weaken)
B. In some cities, streetlights are dimmed or turned off entirely during low-traffic hours without affecting safety. (Weaken)
C. Areas with constant vehicle or pedestrian movement tend to have lights on almost all night, minimizing energy savings. (Strengthen) Select the correct combination:
