Passage: Sporadic and isolated outbursts by Tibetans against the Chinese continued especially during the unrest between September 1987 until March 1989 in the Tibetan areas of the PRC. But it wasn't until 2008 that a large-scale and coordinated uprising erupted coinciding with international protests accompanying the Olympics torch relay that would end in Beijing where the 2008 Summer Olympics were held. What originally began as an annual observance of Tibetan Uprising Day turned into street protests by large numbers of monks from various monasteries for several days. Crowd control and arrests escalated the tensions eventually setting off a riot by thousands of Tibetans in the Ramoche section of Lhasa on March 14, 2008. When the police fled the scene, rioters looted and burned more than 1200 Chinese shops, offices, and residences and set fire to nearly 100 vehicles. In the end, an estimated 22 were dead and 325 injured, mostly Han. Total damage was estimated at $40 million USD. Eventually the paramilitary People's Armed Police were sent in and 50-100 Tibetan rioters were killed before things quieted down. Meanwhile, in the Gansu Province, a demonstration by 400 monks were met with force that ignited riots by more than 5000 Tibetans who again burned down the establishments of local Han and Hui people before security forces arrived. 
Question: How many years after the unrest in the Tibetan areas of the PRC did a large-scale uprising take place?

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: Hoping to rebound from their embarrassing road loss to the Steelers, the Seahawks went home for Sunday Night football, as they hosted the winless New Orleans Saints.  In the first quarter, Seattle trailed early as a blocked punt would result in New Orleans RB Pierre Thomas returning the loose ball 5 yards for a touchdown, along with the only score of the period.  In the second quarter, the 'Hawks continued to trail as Saints QB Drew Brees completed a 3-yard TD pass to TE Eric Johnson, while WR Lance Moore got a 7-yard TD run.  The Seahawks would respond with QB Matt Hasselbeck completing a 17-yard TD pass to WR Ben Obomanu.  However, New Orleans went back to work with Brees completing a 2-yard TD pass to WR Marques Colston.  Seattle would end the half with kicker Josh Brown getting a 52-yard field goal.  After a scoreless third quarter, the 'Hawks tried to rally in the fourth quarter, but all they could get was Hasselbeck's 22-yard TD pass to WR Nate Burleson.
