    Answer: D. Everyone whose train connects with the yellow route may be affected.

    Explanation: Having only one out of 40 trains malfunction seems like a small change in the overall system. However, this small change has large effects on the system as a whole. Many people ride trains that connect to the yellow line. Many people will be stranded at these stations, and some people may try to take different trains than usual in order to get to their destination.
