Example Input: Question: How many wins did Silvana Tirinzoni have going into the Elite 10 in which she lost to Hasselborg? Passage 1:Hasselborg won her first Grand Slam in the lone women's Elite 10 in 2018, going undefeated through the tournament and defeating Silvana Tirinzoni in the final. A few weeks later, she won her second career Stockholm Ladies Cup. Then, at the 2018 Masters, Hasselborg won her second straight slam, defeating Rachel Homan in the final. The following month, Hasselborg and her team took home the gold medal at the 2018 European Curling Championships, her first gold medal at the Euros, defeating Swtizerland's Silvana Tirinzoni rink in the final. Hasselborg lost the world final once again at the 2019 World Women's Curling Championship, this time losing to Silvana Tirinzoni.

 Passage 2:Harris was born in Smithfield, Rhode Island in 1801 and at a young age moved with his parents to Dutchess County, New York where he worked on the family farm and taught school. In 1818 he moved to Ashtabula County, Ohio, but he returned to Rhode Island in 1823 and started working with his uncles William Harris and Samuel Harris in their manufacturing businesses at Valley Falls, Rhode Island and then Albion, Rhode Island. In 1831 Edward Harris started his own small mill in Woonsocket. He eventually built several other successful larger mills in Woonsocket. Harris made large donations to many public causes in Woonsocket, including new roads for the city, the land for Woonsocket High School, the site of Oak Hill Cemetery, and the Harris Institute (a library and auditorium for speakers), which became Woonsocket Harris Public Library, and the former Harris Institute building is now Woonsocket City Hall. Harris served in the Rhode Island State Senate and House of Representatives and was a strong abolitionist and temperance supporter. In the 1840s he ran for governor as the Liberty Party candidate advocating for abolitionism. In 1859 Harris wrote a letter and sent a check to John Brown after his conviction. Harris hosted Abraham Lincoln at his North End home when Lincoln spoke at the Harris Institute in 1860. Harris was married to Rachel Farnham and then after her death to Abby Metcalf and had children in both marriages. Harris died in Woonsocket in 1871. Besides the Harris Institute (Woonsocket City Hall), several of the buildings, which Harris constructed, survive, including Harris Warehouse (1855).
 Passage 3:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Example Input: Question: What was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
 Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nürburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
 Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essaï Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

Example Input: Question: What age was Philip II's assassin when he killed the Macedonian king? Passage 1:Aegae or Aigai (), also Aegeae or Aigeai (Αἰγέαι), was a city in Emathia in ancient Macedonia, and the burial-place of the Macedonian kings. The commanding and picturesque site upon which the town was built was the original centre of the Macedonians, and the residence of the dynasty which sprang from the Temenid Perdiccas. The seat of government was afterwards transferred to the marshes of Pella, which lay in the maritime plain beneath the ridge through which the Lydias forces its way to the sea. But the old capital always remained the national hearth (ἑστία, Diod. Excerpt. p. 563) of the Macedonian race, and the burial-place for their kings. The body of Alexander the Great, though by the intrigues of Ptolemy I Soter, it was taken to Memphis, was to have reposed at Aegae, – the spot where his father Philip II of Macedon fell by the hand of Pausanias of Orestis.
 Passage 2:He was selected as Sepahan's assistant coach in 2006 by Luka Bonačić.

 Passage 3:The maple leaf has been used as a Canadian emblem since the 18th century. It was first used as a national symbol in 1868 when it appeared on the coat of arms of both Ontario and Quebec. In 1867, Alexander Muir composed the patriotic song "The Maple Leaf Forever", which became an unofficial anthem in English-speaking Canada. The maple leaf was later added to the Canadian coat of arms in 1921. From 1876 until 1901, the leaf appeared on all Canadian coins and remained on the penny after 1901. The use of the maple leaf by the Royal Canadian Regiment as a regimental symbol extended back to 1860. During the First World War and Second World War, badges of the Canadian Forces were often based on a maple leaf design. The maple leaf would eventually adorn the tombstones of Canadian military graves.
