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.

Passage: Hoping to rebound from their divisional road loss to the 49ers, the Seahawks went home, donned their alternate uniforms, and prepared for a Week 3 duel with the Chicago Bears. Due to quarterback Matt Hasselbeck's rib injury, Seneca Wallace got the start for the game. Seattle would take flight in the first quarter with Wallace's 39-yard touchdown pass to running back Julius Jones and kicker Olindo Mare's 46-yard field goal. The Seahawks would tack on Mare's 37-yard field goal in the second quarter, yet the Bears would answer with quarterback Jay Cutler's 1-yard touchdown pass to tight end Greg Olsen. Chicago would take in the lead in the third quarter with Cutler's 7-yard touchdown pass to wide receiver Johnny Knox, followed by kicker Robbie Gould's 37-yard field goal. The Seahawks would regain the lead in the fourth quarter with Mare's 39-yard and 46-yard field goal. However, the Bears got the last laugh as Cutler hooked up with wide receiver Devin Hester on a 36-yard touchdown pass (with a successful 2-point conversion pass to wide receiver Earl Bennett). Seattle tried to rally, but Chicago's defense held on for the win.
Question: How many field goals did Mare kick?

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: The site of the current bridge is among several sites of a slave rebellion called the Stono Rebellion, one of the earliest known organized acts against slavery in the Americas. On September 9, 1739, twenty black slaves raided a store near the bridge; in the process they killed two storekeepers and took guns and gunpowder. The bridge survived an attempt by Union forces to burn it during the American Civil War. Union troops floated burning rafts down to the Stono Bridge, hoping the wooden structure would catch fire and burn. However, their efforts were thwarted by a Lieutenant Smith, who along with members of a naval battalion, brought the rafts to shore. There have been several bridges in this location; the last variation was a two lane bridge 1,416 feet -long, which was built in 1928, and later refurbished in 1950. This swing-span drawbridge used a 156-foot -long steel-truss which left little room for even small vessels to pass beneath unless it was open.
Question: How many more slaves were there than shopkeepers killed at the store near Stono Bridge?
