Q: Question: Which of the decidousous plants that border Igelbäcken is the most abundant in the world?  Passage:The upper part of the watershed is constituted of Norra Järvafältet, an open-air area characterized by moraine ridges covered with forests separated by water meadows and tilled fields. While some 20 hectares of the surrounding area is used for pasture, the stream is bordered by deciduous plants such as Alder and Birch and Bulrush can be found in non-shadowed patches. Some 2,5 kilometres from its origin, the stream passes down in a culvert under a traffic route (Akallavägen) and the Barkarby Airport before merging with the stream Djupanbäcken. This part of the catchment area contains a motocross track, a golf driving range, a closed dump, and receives stormwater from the E18 traffic route. Thereafter, the stream flows some 4 km in the valley separating the suburbs Akalla-Hjulsta and Tensta-Rinkeby and where are several rural structures including an ecological farm (Hästa Gård), eight allotment-gardens, and some minor overgrown wetlands. East of the valley the river is crossed by a second traffic route (Kymlingelänken) before flowing 2,5 km through an open grassland to reach a railway and the E4 traffic route, water from the latter treated in a local cleaning plant. The last 1.4 km passes more allotment-gardens and the gardens of the Ulriksdal Palace before jumping into Edsviken through a low dam.

Q: Question: When was the chronicle Liber fundationis completed? Passage:The first recorded sentence in the Polish language reads: "Day ut ia pobrusa, a ti poziwai" ("Let me grind, and you take a rest") — a paraphrase of the Latin "Sine, ut ego etiam molam." The work, in which this phrase appeared, reflects the culture of early Poland. The sentence was written within the Latin language chronicle Liber fundationis from between 1269 and 1273, a history of the Cistercian monastery in Henryków, Silesia. It was recorded by an abbot known simply as Piotr (Peter), referring to an event almost a hundred years earlier. The sentence was supposedly uttered by a Bohemian settler, Bogwal ("Bogwalus Boemus"), a subject of Bolesław the Tall, expressing compassion for his own wife who "very often stood grinding by the quern-stone." Most notable early medieval Polish works in Latin and the Old Polish language include the oldest extant manuscript of fine prose in the Polish language entitled the Holy Cross Sermons, as well as the earliest Polish-language Bible of Queen Zofia and the Chronicle of Janko of Czarnków from the 14th century, not to mention the Puławy Psalter.

Q: Question: Does Amtrak go into Canada? Passage:Everett Station is served by six daily Amtrak trains: four Cascades runs between Seattle and Vancouver, British Columbia, and two Empire Builder runs between Seattle and Chicago. The station is also served by the North Line of Sound Transit's Sounder commuter rail service, running four trains in peak direction towards King Street Station in Seattle during the morning commute and four trains from Seattle during the evening commute, only on weekdays and during special events. Train service to Everett is most often disrupted and canceled during the autumn and winter seasons because of landslides along the shoreline of the Puget Sound, where the BNSF mainline tracks run. During the 2012–2013 winter season, a record-high of 206 passenger trains between Everett and Seattle were canceled, prompting the Washington State Department of Transportation to begin a three-year landslide mitigation project in 2013 that will stabilize slopes above the railroad between Seattle and Everett.
