One 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 is here: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin?
Explanation: The passage describes the 704th's actions during Operation Market Garden, and the answer specifies when the operation happened.

Now, solve this: Passage: Lagunitas Creek's major tributaries include San Geronimo Creek, Devils Gulch, Nicasio Creek, and Olema Creek. The creek's source is the northern slope of Mount Tamalpais, a few miles (~68km) east of Bolinas Lagoon. The creek begins as three forks, the East Fork, Middle Fork and West Fork. After about a mile (1,600 m), they all flow into Lake Lagunitas, which drains into Bon Tempe Lake, which drains into Alpine Lake. Downstream of Alpine Lake, the creek flows roughly northwest until it reaches Kent Lake. Just downstream of Kent Lake, San Geronimo Creek joins the creek. Lagunitas continues northwest through Samuel P. Taylor State Park and is joined by Nicasio Creek, which flows from Nicasio Reservoir, another water storage reservoir. Shortly after this confluence, Lagunitas turns westward and flows through the town of Point Reyes Station. On the west side of the town, the creek is joined by Olema Creek, the largest tributary in the Lagunitas Creek watershed. Olema Creek receives Bear Valley Creek, and mainstem Olema Creek flows for along the San Andreas Fault Zone, with a catchment area of . After receiving the waters of Olema Creek, Lagunitas Creek turns northward and then empties into the wetlands at the southeast end of Tomales Bay.
