Teacher: Now, understand the problem? Solve this instance: Question: What is the name of the settlement that ended NATO's first military intervention since 1989? Passage 1:State Street continues north through the Crescent neighborhood, past the site of the historic Crescent Elementary School, and enters Downtown Sandy. It intersects 10600 South, which becomes State Route 151 a short distance to the west, and passes a large retail area that includes big box stores and the South Towne Mall. The street climbs a small hill to pass over the Jordan and Salt Lake Canal, then passes a cemetery and a small amount of undeveloped greenfield land near the crossing of Dry Creek before reaching a larger hill into which the East Jordan Canal is carved. At the top of this hill, the street passes west of Jordan High School and the South Towne Expo Center before intersecting 9400 South (former State Route 209). A short distance north of that intersection, the East Jordan Canal passes back under the street on its way toward Holladay, and Rio Tinto Stadium fronts onto the street on the west side. Just before the intersection with 9000 South (modern State Route 209), State Street passes the site of a former smelter (which now has a medical center built on part of it). The street forms the western boundary of the Sandy Historic District from 9000 South to Pioneer Avenue (8530 South), and several historic buildings face onto it in this area. There is a traffic signal it the intersection with Sandy's Main Street at 8720 South. North of the historic district, State Street passes through some relatively lightly developed land near the city's border with Midvale, though there are some townhouse developments in progress in the area.
 Passage 2:After the fall of the Berlin Wall in Germany in 1989, the organization conducted its first military interventions in Bosnia from 1992 to 1995 and later Yugoslavia in 1999 during the breakup of Yugoslavia. Politically, the organization sought better relations with former Warsaw Pact countries, most of which joined the alliance in 1999 and 2004. , requiring member states to come to the aid of any member state subject to an armed attack, was invoked for the first and only time after the September 11 attacks, after which troops were deployed to Afghanistan under the NATO-led ISAF. The organization has operated a range of additional roles since then, including sending trainers to Iraq, assisting in counter-piracy operations and in 2011 enforcing a no-fly zone over Libya in accordance with UN Security Council Resolution 1973. The less potent Article 4, which merely invokes consultation among NATO members, has been invoked five times following incidents in the Iraq War, Syrian Civil War, and annexation of Crimea.
