This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992.

Input: Consider Input: Passage: Coming off their home win over the Cowboys, the Vikings flew to Lambeau Field for a Week 7 NFC North Sunday night duel with the Green Bay Packers, as quarterback Brett Favre made his return to take on his former team, in their first meeting on NBC's Sunday Night Football. Minnesota trailed early in the first quarter as Packers running back Brandon Jackson got a 1-yard touchdown run. Afterwards, the Vikings responded as wide receiver Percy Harvin got a 17-yard touchdown run. Green Bay struck back in the second quarter as quarterback Aaron Rodgers completed a 9-yard touchdown pass to tight end Andrew Quarless, yet Minnesota took the lead with running back Adrian Peterson getting a 1-yard touchdown run, followed by kicker Ryan Longwell booting a 28-yard field goal after a bizarre reversal of a touchdown reception by Visanthe Shiancoe. The Packers began the third quarter with Rodgers completing a 14-yard touchdown pass to wide receiver Greg Jennings, followed by linebacker Desmond Bishop returning a Favre interception 32 yards for a touchdown. The Vikings would answer with Favre finding wide receiver Randy Moss on a 4-yard touchdown pass. Minnesota tried to rally in the fourth quarter with an apparent 30-yard touchdown pass from Favre to Harvin with 48 seconds left which would have been the game winner, but Harvin had apparently only one foot in bounds, nullifying the touchdown. Favre tried two more times to get into the end zone, but Green Bay's defense held for the win. 
Question: How many yards was the first touchdown of the game?

Output: 1.


Input: Consider Input: Passage: The Bengals started the season at home against the Ravens.  In the first quarter, the Ravens scored as Justin Tucker kicked a 25-yard field goal to make it 3-0.  They would increase their lead in the second quarter when Joe Flacco found Jeremy Maclin on a 48-yard pass to make it 10-0.  This would be followed up by a 2-yard touchdown run by Terrence West to make the score 17-0 at halftime.  In the third quarter, the Ravens would go back to work with Tucker kicking yet another 25-yard field goal to make the score 20-0.  A scoreless fourth quarter made this the eventual final score of the game. With the loss, the Bengals started their season 0-1.  This is the team's first shut-out loss at home since 2001. Andy Dalton set a new career high for total turnovers in a game with 5 (4 interceptions, 1 lost fumble). 
Question: How many more points were scored in the first half than the second? 
Answer type: Number

Input: Consider Input: Passage: During the 19th century, the major European powers went to great lengths to maintain a balance of power throughout Europe, resulting in the existence of a complex network of political and military alliances throughout the continent by 1900. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria. When Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors  between the monarchs of Austria-Hungary, Russia and Germany. This agreement failed because Austria-Hungary and Russia could not agree over Balkan policy, leaving Germany and Austria-Hungary in an alliance formed in 1879, called the Dual Alliance. This was seen as a method of countering Russian influence in the Balkans as the Ottoman Empire continued to weaken. This alliance expanded in 1882 to include Italy, in what became the Triple Alliance. Bismarck had especially worked to hold Russia at Germany's side in an effort to avoid a two-front war with France and Russia. When Wilhelm II ascended to the throne as German Emperor , Bismarck was compelled to retire and his system of alliances was gradually de-emphasised. For example, the Kaiser refused, in 1890, to renew the Reinsurance Treaty with Russia. Two years later, the Franco-Russian Alliance was signed to counteract the force of the Triple Alliance. In 1904, Britain signed a series of agreements with France, the Entente Cordiale, and in 1907, Britain and Russia signed the Anglo-Russian Convention. While these agreements did not formally ally Britain with France or Russia, they made British entry into any future conflict involving France or Russia a possibility, and the system of interlocking bilateral agreements became known as the Triple Entente. 
Question: How many years did the Dual Alliance last before it became the Triple Alliance and include Italy? 
Answer type: Number 


Output: 3.
