In the first quarter, Seattle trailed early as Bears RB Cedric Benson got a 43-yard TD run, along with kicker Robbie Gould getting a 31-yard field goal.  The Seahawks would get on the board with QB Matt Hasselbeck completing a 19-yard TD pass to WR D. J. Hackett.  In the second quarter, the Seahawks took the lead with RB Maurice Morris getting a 19-yard TD run.  However, Chicago regained the lead with RB Adrian Peterson getting a 5-yard TD run.

In the third quarter, the Seahwaks retook the lead as Hasselbeck completed a 4-yard TD pass to WR Nate Burleson for the only score of the period.  In the fourth quarter, the Bears tried to retaliate as Gould kicked a 47-yard field goal.  Afterwards, Seattle pulled away with Brown kicking a 23-yard and a 46-yard field goal.

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?

Passage: However, on Tuesday, 7 February 2012, it was confirmed that Cardiff Blues would face Connacht Rugby at the Arms Park on Friday, 10 February 2012. The Pro14 League game result was a win for the Cardiff Blues 22–15 and attendance of 8,000. The following Tuesday, it was announced that the match against Ulster Rugby on Friday, 17 February, would also be at the Arms Park, resulting in a Blues win, 21–14 and attendance of 8,600. The agreement signed during 2009 tied Cardiff Blues to a 20-year contract to play a maximum of 18 games per season for a set fee, rather than per match at Cardiff City Stadium. But on 23 February, it was announced that the two Welsh derbies against the Scarlets and the Ospreys (rugby union) would be played at Cardiff City Stadium, rather than the Arms Park, because of Cardiff Blues anticipation that the attendance figures would far exceed the maximum capacity of 9,000. On 8 May 2012, it was announced that Cardiff Blues would be returning to the Arms Park on a permanent basis after just three years at the Cardiff City Stadium. 
Question: How many years of the 20 year contract did the Cardiff Blues not play at Cardiff City Stadium?
