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. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

Example Input: Passage: Salks vaccine was then used in a test called the Francis Field Trial, led by Thomas Francis, Jr., the largest medical experiment in history at that time. The test began with about 4,000 children at Franklin Sherman Elementary School in McLean, Virginia, and eventually involved 1.8 million children, in 44 states from Maine to California. By the conclusion of the study, roughly 440,000 received one or more injections of the vaccine, about 210,000 children received a placebo, consisting of harmless culture media, and 1.2 million children received no vaccination and served as a control group, who would then be observed to see if any contracted polio. The results of the field trial were announced 12 April 1955 (the tenth anniversary of the death of President Franklin D. Roosevelt, whose Franklin D. Roosevelts paralytic illness was generally believed to have been caused by polio). The Salk vaccine had been 60-70% effective against PV1 (poliovirus type 1), over 90% effective against PV2 and PV3, and 94% effective against the development of bulbar polio. Soon after Salks vaccine was licensed in 1955, childrens vaccination campaigns were launched. In the U.S, following a mass immunization campaign promoted by the March of Dimes, the annual number of polio cases fell from 35,000 in 1953 to 5,600 by 1957. By 1961 only 161 cases were recorded in the United States.
Question: How many states chose not to particpate in the Salks vaccine?
Answer type: Number
Example Output: 6.

Example Input: Passage: Diaz created a formidable political machine, first working with regional strongmen and bringing them into his regime, then replacing them with jefes politicos who were loyal to him. He skillfully managed political conflict and reined in tendencies toward autonomy. He appointed a number of military officers to state governorships, including General Bernardo Reyes, who became governor of the northern state of Nuevo Leon, but over the years military men were largely replaced by civilians loyal to Diaz. As a military man himself, and one who had intervened directly in politics to seize the presidency in 1876, Diaz was acutely aware that the Federal Army could oppose him. He augmented the rurales, a police force created by Juarez, making them his personal armed force. The rurales were only 2,500 in number, as opposed to the 30,000 in the Federal Army and another 30,000 in the Federal Auxiliaries, Irregulars, and National Guard. Despite their small numbers, the rurales were highly effective in bringing control to the countryside, especially along the 12,000 miles of railway lines. They were a mobile force, often put on trains with their horses to put down rebellions in relatively remote areas of Mexico.
Question: How many total soldiers were in the Federal armed forces?
Answer type: Number
Example Output: 60000.

Example Input: Passage: After the first three possessions of the game ended in punts, the Patriots marched 62 yards to the Bills 14-yard line, but the drive ended with Gostkowski missing a 36-yard field goal. On the third play of the Bills resulting possession, though, Kyle Orton was intercepted by Jamie Collins at the Patriots 39-yard line. The Patriots marched 61 yards in just five plays to take the lead on a 1-yard touchdown pass from Brady to Tim Wright. After both teams punted, the Bills lugged 67 yards in just under 5 minutes to tie the game 7-7 on a Kyle Orton touchdown pass to Robert Woods. After a Patriots three-and-out, Orton was strip-sacked by Chandler Jones with Jones recovering at the Bills 24. The Patriots didn't gain a single yard, however, but Gostkowski was successful on a 42-yard field goal try. With 0:06 seconds left in the half, the Bills were attempting to run out the clock, but McCourty stripped C. J. Spiller with Zach Moore recovering at the Bills 42. Brady hit Edelman on a quick 7 yards pass and Gostkowski kicked a 53-yarder for a 13-7 lead at the half. After receiving the opening kickoff of the second half the Patriots reached the Bills 43 in just five plays before Brady launched a bomb to Brian Tyms for a 43-yard touchdown, increasing the New England lead to 20-7. The Bills struck right back with a 13 play, 80-yard drive in just under 7 minutes, culminating in Fred Jackson scoring on a 1-yard touchdown run. The Patriots marched 56 yards on their next possession with Gostkowski adding a 40-yard field goal to increase the lead to 23-14. After a Bills punt Brady led the Patriots down the field and, with just over 6 minutes remaining, found his favorite target, Gronkowski, for a 17-yard touchdown, but the play was nullified for an offensive holding penalty on Jordan Devey. This would prove to just be a delay, because Brady threw an 18-yard touchdown pass to LaFell two plays later, capping a 12 play, 80-yard drive. The Patriots now led 30-14 and looked to be well on their way to victory. However, the Bills wouldn't go away quietly. Kyle Orton calmly engineered an 8 play, 80-yard drive, aided by a 35-yard completion on 4th-and-2, that ended in his 8-yard touchdown pass to Chris Hogan, with a successful two-point conversion, trimming the deficit to one possession, 30-22. Starting at the Patriots 7, Brady converted a 3rd-and-16 with a 17-yard completion to Gronkowski, and a few plays later found LaFell on a medium pass, who turned upfield and raced down the sideline for a 56-yard touchdown, increasing the Patriots lead to 37-22. The Bills reached their own 42 on their final drive, but a sack by Rob Ninkovich and an incomplete pass intended for Scott Chandler on 4th-and-9 officially sealed the deal. Brady completed 27 of 37 passes for 361 yards, with 4 touchdowns and no interceptions. Kyle Orton was equally very impressive, finishing the game 24 of 38 for 299 yards, with 2 TDs and 1 INT. With 4 catches for 97 yards and 2 touchdowns, LaFell continued to be the Patriots awaited deep-threat at wide receiver. Both teams struggled to run the football. Stevan Ridley ran for only 23 yards on 10 carries, while Fred Jackson ran for only 26 yards on 10 carries. Unfortunately, it was later learned the Patriots lost Stevan Ridley and linebacker Jerod Mayo to season ending injuries.
