Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Link Information: Operation Market Garden was a failed World War II military operation fought in the Netherlands from 17 to 25 September 1944. Answer: from 17 to 25 September 1944
Solution: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin?
Reason: The passage describes the 704th's actions during Operation Market Garden, and the answer specifies when the operation happened.

Now, solve this instance: Passage: Mike Hoover is an American mountaineer, rock climber and cinematographer. He first became known for an Academy Award-nominated documentary short, Solo, in which he climbed El Capitan solo. His first major involvement in commercial film was with The Eiger Sanction (1975), in which he taught Clint Eastwood how to climb in the Yosemite valley before the film was shot in Grindelwald, Switzerland in 1974. Hoover has since been a cinematographer for the documentaries To the Ends of the Earth (1983), To the Limit (1989), The Endless Summer 2 (1994) and Zion Canyon: Treasure of the Gods. In the late 1980s, he made 18 trips to Afghanistan to shoot war footage that was later featured in a program named The Battle for Afghanistan (1987). Hoover has led various film teams all over the world, particularly in physically and politically difficult locations, such as Everest, K2, the precarious rock faces of the Eiger and the Venezuelan jungle.
Link Information: After his successful solo ascent of the Leaning Tower, Royal Robbins turned his attention to the Yvon Chouinard-T.M. Herbert Muir Wall route, completing the first solo ascent of El Capitan during a 10-day push in 1968. The first solo ascents of El Capitan's four classic "siege" routes were accomplished by Thomas Bauman on The Nose in 1969; Peter Hann on the Salathe Wall in 1972; Robert Kayen on the Layton Kor-Steve Roper West Buttress route in 1982; and Beverly Johnson on the Cooper-Baldwin-Denny Dihedral Wall route in 1978. Other noteworthy early solo ascents were the solo first ascent of Cosmos by Jim Dunn in 1972, Zodiac by Charlie Porter in 1972; Tangerine Trip by David Mittel in 1985; and The Pacific Ocean Wall by Robert Slater in 1982. These ascents were long 7- to 14-day ordeals that required the solo climber lead each pitch, and then rappel, clean the climbing gear, reascend the lead rope, and haul equipment, food, and water using a second haul rope. Answer: 10
Student:
How many people climbed El Capitan solo before Mike Hoover?
