Question

Sadao had taken this into his mind as he did everything his father said, his father who never joked or played with him but who spent infinite pains upon him who was his only son. Sadao knew that his education was his father's chief concern. For this reason, he had been sent at twenty-two to America to learn all that could be learned of surgery and medicine. He had come back at thirty, and before his father died he had seen Sadao become famous not only as a surgeon but as a scientist. Because he was perfecting a discovery which would render wounds entirely clean, he had not been sent abroad with the troops. Also, he knew, there was some slight danger that the old General might need an operation for a condition for which he was now being treated medically, and for this possibility, Sadao was being kept in Japan.
