Input: Consider Input: Passage: Following their bye week, the Raiders traveled to Mexico City for a home game against the AFC-leading Patriots. With a loss by the Chiefs earlier in the day, the Raiders looked to move within one game of the division lead. The Patriots quickly shut out any hope of a win, scoring touchdowns on two of their first three possessions to take a 14-0 lead. With under two minutes remaining in the half, the Raiders drove inside the New England 20 yard line in an attempt to cut the lead in half. Derek Carr hit Seth Roberts at the New England three, but Roberts did not properly secure the ball and fumbled, turning the ball over to Tom Brady and the Patriots with 33 seconds remaining in the half. New England quickly moved to the Raider 45 and Stephen Gostkowski connected on a 62-yard field goal as the half ended to move the lead to 17-0. In the second half, things got even worse for the Raiders as the Patriots scored on their third play, a Brady 64-yard pass to Brandin Cooks to extend the lead to 24 and end any hope of a Raider win. Two more Gostkowski field goals in the third quarter moved the lead to 30-0 entering the fourth quarter. Carr did hit Amari Cooper from nine yards out and converted the two-point play early in the fourth quarter. Another Gostkowski field goal ended the scoring as the Patriots dismantled the Raiders 33-8. The loss moved the Raiders to 4-6 on the season as they remained two games behind the Chiefs in the AFC West. The Raiders were out-gained 420-344 on the day as the Raiders' defense continued its season-long struggle. 
Question: How many points were the Raiders trailing by at halftime?

Input: Consider 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 

Output: 6.
