Quizplus · Accepted Answer

The graph suggests a relationship between the frequency of service and the number of passengers, indicating that as the frequency increases, so does the number of passengers. However, it does not provide information on other potential factors that could influence passenger numbers, making choice D incorrect to conclude solely from the graph.
