Step 1: Understanding the Concept:
This question again delves into the perspective of Jim, the narrator of 'The Pace for Living'. It asks what he believes people are unwilling to change.
Step 2: Detailed Explanation:
Jim is deeply critical of the modern way of life—the obsession with speed, machines, and efficiency. This entire system constitutes his 'environment'.
He feels that everyone is caught up in this race and no one is willing to question it or try to change it. They accept this fast-paced, machine-driven environment as normal.
The word 'environment' here refers not just to the natural world but to the social and cultural atmosphere of the time, which Jim finds oppressive.
Step 3: Final Answer:
Jim feels a sense of helplessness because he believes nobody is willing to do anything to change the fast-paced modern environment.
