[Q]: Passage: Coming off their road win over the Browns, the Packers went home for the highly anticipated Week 8 divisional rematch with the  Minnesota Vikings, as former Green Bay Packers quarterback Brett Favre made his return to face his former team. The Packers got the game off to quick start in the first quarter as kicker Mason Crosby made a 37-yard field goal, but the Vikings responded with running back Adrian Peterson's 1-yard touchdown run.  Things got worse for Green Bay in the second quarter as Favre completed a 12-yard touchdown pass to tight end Visanthe Shiancoe, followed by kicker Ryan Longwell (another former Packer) nailing a 41-yard field goal.  The Packers would end the first half with 48 yards of offense, the lowest in over 10 years for a Packers team. Minnesota would add onto their lead in the third quarter as Favre found wide receiver Percy Harvin on a 51-yard touchdown pass as 3 Packer defenders collided and hit the ground. Yet Green Bay began to rally as Crosby booted a 26-yard field goal, followed up by quarterback Aaron Rodgers completing a 16-yard and a 5-yard touchdown pass to tight end Spencer Havner.  The Vikings would answer in the fourth quarter as Favre hooked up with tight end/fullback Jeff Dugan on a 2-yard touchdown pass.  The Packers tried to rally as Rodgers connected with wide receiver Greg Jennings on a 10-yard touchdown pass (with a failed 2-point conversion), but Minnesota would put the game out of reach as Favre hooked up with wide receiver Bernard Berrian on a 16-yard touchdown pass.  Favre threw 4 TD's with 0 INT, and had a passer rating of 128. With the loss, Green Bay fell to 4-3 and were swept by the Vikings for the first time since 2005. 
Question: How many touchdowns did the Vikings score in the first half?

[Q]: 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 
[A]: 6.


[Q]: Passage: Following the high-scoring loss to the Packers, the Vikings, continuing with Christian Ponder as their quarterback, travel to Arlington, Texas to face the Dallas Cowboys. The first quarter was all field goals, as Dallas scored first with a 41-yarder by Dan Bailey, followed by a 23-yarder for the Vikings by Blair Walsh. In the second quarter, Bailey made another field goal from 44 yards to put the Cowboys up by 3, but the Vikings took a 10-6 lead into halftime, capping the ensuing 79-yard drive with a 6-yard run by Ponder. After the half, Cowboy quarterback Tony Romo completed two consecutive 26-yard passes to tight end Jason Witten to give them an early touchdown and restore their three-point lead. On the very next play from scrimmage, Ponder fumbled the ball as he was sacked in the end zone, and the Cowboys' Nick Hayden recovered it for a touchdown, meaning the Vikings went from 10-6 up to 20-10 down in the space of two scrimmage plays. The Vikings responded immediately with a quick, six-play drive, culminating with a 31-yard pass from Ponder to Kyle Rudolph to cut the Cowboys' lead back to three points. After a series of punts going into the fourth quarter, Adrian Peterson scored for the Vikings with an 11-yard run with almost six minutes to go, but Walsh pushed the extra point kick wide right, giving the Vikings a three-point lead over the Cowboys. Vikings cornerback A. J. Jefferson intercepted Romo on the Cowboys' ensuing drive, putting the Vikings in a position to potentially take over the game, but the offense went three-and-out and was forced to punt. The Cowboys progressed downfield quickly, never faced with a third down, and scored with a 7-yard touchdown pass from Romo to Dwayne Harris, the third time the Vikings had given up a game-winning score in 2013. With less than 30 seconds to play, but they were unable to make any significant territorial gains and Ponder's last-second hail mary fell short, giving the Cowboys a 27-23 win. 
Question: How many points were scored in the second half of the game?
