Passage: The start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland; the United Kingdom and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and the two wars merged in 1941. This article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. The exact date of the war's end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945 , rather than the formal surrender of Japan, which was on 2 September 1945 that officially ended the war in Asia. A peace treaty with Japan was signed in 1951. A treaty regarding Germany's future allowed the reunification of East and West Germany to take place in 1990 and resolved most post-World War II issues. A formal peace treaty between Japan and the USSR had never been signed. 
Question: How many months did the Battles of Khalkhin Gol last?

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 7-2 Patriots faced the 6-3 Colts in a primetime match up on Sunday Night Football, with two of the best passing offenses in the NFL. The Patriots came in looking for their sixth straight win. After forcing the Colts to a quick three-and-out, the Patriots scored on their opening drive of the game, covering 89 yards, in 11 plays scoring on a 4-yard touchdown run by rookie Jonas Gray. The Colts responded, aided by a 46-yard completion from Luck to T. Y. Hilton, driving to the Patriots 13, but had to settle for an Adam Vinatieri 31-yard field goal to bring the score to 7-3. The Patriots then drove to their own 49, but safety Mike Adams intercepted a pass intended for Tyms at the Colts 6 for no gain. On their next possession, the Colts reached the Patriots 32, but McCourty intercepted Luck and returned it 10 yards back to the Patriots 32. From there the Patriots struck on an 11-play, 68-yard drive, scoring on Gray's 2-yard touchdown run, extending the lead to 14-3. The Patriots forced a three-and-out, but on the third play of the Patriots next drive, Brady was intercepted by Adams again, who returned it 10 yards to the Patriots 23. With the fabulous field position, it took the Colts just three plays for Luck to find Hakeem Nicks on a 10-yard touchdown pass, making the score 14-10 with less than a minute remaining in the first half. After taking the kickoff, the Patriots restarted with an 8 play, 80-yard drive scoring on a  2-yard touchdown pass from Brady to Wright, extending the lead to 21-10. The Colts drove to the Patriots 40 on their next drive, and Vinatieri was good from 53 yards away to trim the deficit to 21-13. The Patriots struck with another touchdown, with Brady passing for 56 yards on a 10-play, 80-yard drive before Gray scored on a 2-yard touchdown run and increasing the Patriots lead to 28-13. The Colts pulled back into the game on their next drive, with Luck completing 5 passes on the next drive for 77 yards, capping it off with his 1-yard touchdown pass to Anthony Castonzo, pulling the game back to 28-20. Despite the effort from Luck and the offense, the Colt defense had no answer for the Patriots, with them driving 80 more yards in 10 more plays, scoring on Gray's 1-yard touchdown run, his fourth, increasing the lead to 35-20 with just 8:43 remaining. The Colts actually stuffed Gray for a two-yard loss at the Colts 31 which would've made it 4th-and-4, but a 15-yard face mask penalty on Jerrell Freeman moved the ball to the 14 and Gray scored 4 plays later. Four straight incompletions gave the Patriots the ball at the Colts 32. After two three-yard runs by Gray, Tom Brady threw a short pass to Gronkowski who broke it off for a 26-yard touchdown, effectively ending the game and clinching the Patriots' sixth straight win. The game also saw several skirmishes between Gronkowski and Sergio Brown, with Gronkowski throwing Brown into an NBC camera after the play on Gray's 4th touchdown. Gronkowski referred to this incident as throwing Sergio Brown "out of the club" for talking trash all game, including posting Gronk's stats on Twitter during the game. Jonas Gray broke out, running all over the Colts for 201 yards and 4 touchdowns on 37 carries. Tom Brady threw for 257 yards and two touchdowns, but threw two interceptions. The Patriots scored on every drive of the second half with exception of their final drive of the game which was used to run out the clock. Luck threw for 303 yards and two touchdowns, but the running game was a non-factor, totaling just 19 yards on 16 carries, with Trent Richardson running 6 times for 0 yards. Tom Brady improved to 3-0 against Andrew Luck.
