Input: Consider Input: Passage: On 4 May 1918, in the aftermath of the Finnish Civil War, Silatch arrived secretly in Kotka, Finland, to evacuate remaining members of the Finnish Red Guard. However, she was confiscated by the Finns and joined the Finnish icebreaker fleet as Ilmarinen, after the legendary hero from Kalevala. In December 1919 she was sent to Koivisto to assist three Finnish torpedo boats, C1, C2 and C3 that had been surrounded by ice some thick. The 150-ton torpedo boats had participated in the British campaign in the Baltic, and Admiral Walter Cowan had demanded that the Finnish squadron patrolling the area had to stay until the British forces had withdrawn. Despite the efforts of Ilmarinen, the weak-hulled torpedo boats were crushed by the ice, and the newly founded Finnish Navy lost one fifth of its ships. After the winter of 1919 Ilmarinen was laid up until she was returned to the Soviet Union according to the Treaty of Tartu. In turn the Soviets gave back the Finnish icebreaker Avance. The name Ilmarinen was later given to a Finnish coastal defence ship launched in 1931.
 Link Information: The treaty confirmed that the Finnish-Soviet border would follow the old border between the autonomous Grand Duchy of Finland and Imperial Russia.  Answer: Russia

Output: WHich countries participated in the Treaty that returned Silatch to the Soviet Union?


Input: Consider Input: Passage: In August 2012, he made his European debut for the club, coming on as a substitute in a UEFA Europa League qualifying match against Gomel, replacing Joe Cole in a 0–1 away win. The following week, Sterling scored his first goal for the senior team with a first-half strike in a friendly against Bayer Leverkusen. On 23 August 2012, he started his first match for Liverpool in a Europa League qualifying match away to Hearts in a 0–1 win. He was given his first start in the league three days later in a 2–2 draw at Anfield to Manchester City. He played the full 90 minutes in the loss to Arsenal on 2 September, and the draw with Sunderland on 15 September, where he registered one assist and was named man of the match. On 19 September, Sterling was one of the group of teenagers that travelled to Switzerland to play Young Boys in a UEFA Europa League group match. He replaced Stewart Downing in the second half as Liverpool won 3–5. On 20 October, Sterling scored his first senior competitive goal for Liverpool in the 29th minute in a 1–0 league win against Reading with a strike from the edge of the box. As a result, he became the second-youngest player ever to score in a competitive fixture for Liverpool, behind only Michael Owen.

Input: Consider Input: Passage: Free-agent goaltender Jeff Hackett was signed from the Boston Bruins to replace Roman Cechmanek and challenge backup Robert Esche for the number one spot in 2003–04, but Hackett was forced to retire in February due to vertigo. During the course of the season, serious injuries suffered by both Jeremy Roenick (broken jaw) and Keith Primeau (concussion) in February forced the Flyers to trade for the Chicago Blackhawks' Alexei Zhamnov, who filled in well and kept the Flyers afloat. Esche entrenched himself as starter and remained in that position even after the Flyers re-acquired Sean Burke from the Phoenix Coyotes, as the Flyers clinched the Atlantic Division title over the New Jersey Devils on the last day of the season.
 Link Information: He played for HC Vsetín Answer: 7


Output: How many teams did the goaltender that Jeff Hackett replaced play for?
