The city of Metropolis aims to reduce morning traffic congestion in the downtown core, defines as the average time spent waiting at red lights, by 20%.
To achieve this, the council has installed a new, highly advanced synchronization system for all traffic lights, an investment that cost $12 million.
Since this system can increase the number of vehicles that pass through major intersections every hour by an average of 25%, the city council concludes that the installation of new system will ensure that the city meets its congestion reduction target.

Incorrect
C. If increased traffic flow through major intersections after implementation of new system will drive more traffic towards downtown core, then congestion reduction target by 20% may not be met.
Correct
D. It is mentioned that the new system can increase the number of vehicles that pass through major intersections every hour by an average of 25% which is comparison statistics with older traffic light system.
