Answer:
"And still his desire to look just once upon a real prince, in the flesh, grew upon him, day by day, and week by week, until at last it absorbed all other desires, and become the one passion of his life."
Step-by-step explanation:
The excerpt shown above shows that Tom's greatest desire in his life is to be able to see a real prince, which is the only passion he has, which consumes him every week. This shows that Tom cannot see a prince in him, cannot believe that he is one. It makes him dissatisfied and when we are dissatisfied with something, we start to want it to change, like Tom is doing. Every day he sees himself as a fake prince, but the desire to see a real prince intensifies.
