Q: Paragraph- Sent 1: As his car slid downtown on Tuesday morning the mind of Arnold Thorndike was occupied with such details of daily routine as the purchase of a railroad, the Japanese loan, the new wing to his art gallery, and an attack that morning, in his own newspaper, upon his pet trust.
Sent 2: But his busy mind was not too occupied to return the salutes of the traffic policemen who cleared the way for him.
Sent 3: Or, by some genius of memory, to recall the fact that it was on this morning young Spear was to be sentenced for theft.
Sent 4: It was a charming morning.
Sent 5: The spring was at full tide, and the air was sweet and clean.
Sent 6: Mr. Thorndike considered whimsically that to send a man to jail with the memory of such a morning clinging to him was adding a year to his sentence.
Sent 7: He regretted he had not given the probation officer a stronger letter.
Sent 8: He remembered the young man now, and favorably.
Sent 9: A shy, silent youth, deft in work, and at other times conscious and embarrassed.
Sent 10: But that, on the part of a stenographer, in the presence of the Wisest Man in Wall Street, was not unnatural.
Sent 11: On occasions, Mr. Thorndike had put even royalty— frayed, impecunious royalty, on the lookout for a loan—at its ease.
Sent 12: The hood of the car was down, and the taste of the air, warmed by the sun, was grateful.
Sent 13: It was at this time, a year before, that young Spear picked the spring flowers to take to his mother.
Sent 14: A year from now where would young Spear be?
Sent 15: It was characteristic of the great man to act quickly, so quickly that his friends declared he was a slave to impulse.
Sent 16: It was these same impulses, leading so invariably to success, that made his enemies call him the Wisest Man.
Sent 17: He leaned forward and touched the chauffeur's shoulder.
Sent 18: "Stop at the Court of General Sessions," he commanded.
Sent 19: What he proposed to do would take but a few minutes.
Sent 20: A word, a personal word from him to the district attorney, or the judge, would be enough.
