Input: The Bush administration did not develop new diplomatic initiatives on al Qaeda with the Saudi government before 9/11. Vice President Cheney called Crown Prince Abdullah on July 5, 2001, to seek Saudi help in preventing threatened attacks on American facilities in the Kingdom. Secretary of State Powell met with the crown prince twice before 9/11. They discussed topics like Iraq, not al Qaeda.U.S.-Saudi relations in the summer of 2001 were marked by sometimes heated disagreements about ongoing Israeli- Palestinian violence, not about Bin Laden. The confirmation of the Pentagon's new leadership was a lengthy process. Deputy Secretary Wolfowitz was confirmed in March 2001 and Under Secretary of Defense for Policy Douglas Feith in July. Though the new officials were briefed about terrorism and some of the earlier planning, including that for Operation Infinite Resolve, they were focused, as Secretary Rumsfeld told us, on creating a twenty-first-century military. At the Joint Chiefs of Staff, General Shelton did not recall much interest by the new administration in military options against al Qaeda in Afghanistan. He could not recall any specific guidance on the topic from the secretary. Brian Sheridan-the outgoing assistant secretary of defense for special operations and low-intensity conflict (SOLIC), the key counterterrorism policy office in the Pentagon-never briefed Rumsfeld. He departed on January 20; he had not been replaced by 9/11. Rumsfeld noted to us his own interest in terrorism, which came up often in his regular meetings with Tenet. He thought that the Defense Department, before 9/11, was not organized adequately or prepared to deal with new threats like terrorism. But his time was consumed with getting new officials in place and working on the foundation documents of a new defense policy, the quadrennial defense review, the defense planning guidance, and the existing contingency plans. He did not recall any particular counterterrorism issue that engaged his attention before 9/11, other than the development of the Predator unmanned aircraft system. The commander of Central Command, General Franks, told us that he did not regard the existing plans as serious. To him a real military plan to address al Qaeda would need to go all the way, following through the details of a full campaign (including the political-military issues of where operations would be based) and securing the rights to fly over neighboring countries. The draft presidential directive circulated in June 2001 began its discussion of the military by reiterating the Defense Department's lead role in protecting its forces abroad.

Does the response "Assistant secretary of defense for special operations and low-intensity conflict" correctly answer the question "What position was vacant from January 2001 and had not been replaced before 9/11?"?

Input: (CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said.

Does the response "Jo-Wilfried Tsonga" correctly answer the question "What two players beat Federer in the quarterfinals?"?

Input: Brad, Texas (CNN) -- Authorities were working on plans Friday for residents who were forced to flee a wildfire in northern Texas to return home, a day after firefighters made progress battling the blaze that destroyed dozens of homes. The blaze in Palo Pinto County scorched 6,200 acres by Thursday, according to the Texas Forest Service. The fire is burning near the resort of Possum Kingdom Lake, near the town of Brad, about 100 miles west of Dallas. "We feel much better about this fire today," as the blaze is now 50% contained, said John Nichols, a spokesman for the Forest Service. He said evacuations were lifted for some residents forced to evacuate the fire, which was driven by high temperatures and dry winds. The wildfire has destroyed 40 homes and nine RVs since it began Tuesday, the Forest Service said Thursday. Firefighters were receiving support from aerial tankers and helicopters. Authorities are mapping out plans to allow residents to return to their homes, said Palo Pinto County Sheriff Ira Mercer. Authorities also are trying to open the lake for the Labor Day holiday, he said. On Wednesday, evacuations were ordered in several communities on the north side of the lake after the fire charged over a ridge and approached a dam on the lake, CNN affiliate WFAA reported. The wildfire was moving so fast that the Forest Service pulled out of its command observation post, telling journalists and onlookers to get out of the way of the fire. "My house is right through here, though it may be gone," Tom Hardeston told WFAA as he watched the fire. Nearby ranchers battled to save their herds from the encroaching fire. "I'm just moving them from pasture to pasture," Cindi McCoy told WFAA, referring to her livestock. "As one pasture burns, I'm moving them back to that one and bring(ing) them back around."

Does the response "Wednesday" correctly answer the question "When was the blaze 50 percent contained?"?
