Input: Consider Input: Question: What was the primary focus of the paper Royster had worked for before the war? Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

Input: Consider Input: Question: Which race that Frankel won in his four-year-old season had a higher purse? Passage:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."
