Question: In 1983 fighting between Palestinian refugees and Lebanese factions reignited that nation's long-running civil war. A UN agreement brought an international force of peacekeepers to occupy Beirut and guarantee security. US Marines landed in August 1982 along with Italian and French forces. On October 23, 1983, a suicide bomber driving a truck filled with 6 tons of TNT crashed through a fence and destroyed the Marine barracks, killing 241 Marines; seconds later, a second bomber leveled a French barracks, killing 58. Subsequently the US Navy engaged in bombing of militia positions inside Lebanon. While US President Ronald Reagan was initially defiant, political pressure at home eventually forced the withdrawal of the Marines in February 1984.

Answer: 241
Question: Some evidence shows that alternatives to pesticides can be equally effective as the use of chemicals. For example, Sweden has halved its use of pesticides with hardly any reduction in crops.[unreliable source?] In Indonesia, farmers have reduced pesticide use on rice fields by 65% and experienced a 15% crop increase.[unreliable source?] A study of Maize fields in northern Florida found that the application of composted yard waste with high carbon to nitrogen ratio to agricultural fields was highly effective at reducing the population of plant-parasitic nematodes and increasing crop yield, with yield increases ranging from 10% to 212%; the observed effects were long-term, often not appearing until the third season of the study.
Try to answer this question if possible: What was the range of yield increases in Sweden during the study?
Answer: unanswerable
Question: Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.

Answer: unanswerable
Question: The landscapes of Thuringia are quite diverse. The far north is occupied by the Harz mountains, followed by the Goldene Aue, a fertile floodplain around Nordhausen with the Helme as most important river. The north-west includes the Eichsfeld, a hilly and sometimes forested region, where the Leine river emanates. The central and northern part of Thuringia is defined by the 3000 km wide Thuringian Basin, a very fertile and flat area around the Unstrut river and completely surrounded by the following hill chains (clockwise from the north-west): Dun, Hainleite, Windleite, Kyffhauser, Hohe Schrecke, Schmucke, Finne, Ettersberg, Steigerwald, Thuringian Forest, Horselberge and Hainich. Within the Basin the smaller hill chains Fahner Hohe and Heilinger Hohen. South of the Thuringian Basin is the Land's largest mountain range, marked by the Thuringian Forest in the north-west, the Thuringian Highland in the middle and the Franconian Forest in the south-east. Most of this range is forested and the Groer Beerberg (983 m) is Thuringia's highest mountain. To the south-west, the Forest is followed up by Werra river valley, dividing it from the Rhon Mountains in the west and the Grabfeld plain in the south. Eastern Thuringia, commonly described as the area east of Saale and Loquitz valley, is marked by a hilly landscape, rising slowly from the flat north to the mountainous south. The Saale in the west and the Weie Elster in the east are the two big rivers running from south to north and forming densely settled valleys in this area. Between them lies the flat and forested Holzland in the north, the flat and fertile Orlasenke in the middle and the Vogtland, a hilly but in most parts non-forested region in the south. The far eastern region (east of Weie Elster) is the Osterland or Altenburger Land along Pleie river, a flat, fertile and densely settled agricultural area.
