[EX Q]: Passage: The Cowboys began their 2007 campaign at home against their NFC East rival, the New York Giants.  In the first quarter, Dallas trailed early as QB Eli Manning completed a 60-yard TD pass to WR Plaxico Burress to give New York an early 6-0 lead (botched hold on PAT).  Afterwards, the Cowboys got on the board with rookie kicker Nick Folk getting a 31-yard field goal.  In the second quarter, Dallas took the lead with RB Marion Barber getting an 18-yard TD run, while QB Tony Romo completed an 18-yard TD pass to TE Jason Witten.  Afterwards, the Giants would end up trailing by one at halftime, as Manning & Burress hooked up with each other again on a 4-yard TD pass, while kicker Lawrence Tynes got a 44-yard field goal. In the third quarter, Dallas responded with Romo completing a 22-yard TD pass to WR Terrell Owens.  New York would climb back with Tynes kicking a 48-yard field goal, but the Cowboys answered with Romo running into the end zone from 9 yards out.  In the fourth quarter, the Giants managed to try to come back with Tynes' 24-yard field goal, yet Dallas would reply with Romo & Owens hooking up with each other again on a 47-yard TD pass.  Just when it looked like New York was drawing closer with Manning's 9-yard TD pass to RB Derrick Ward (with a failed 2-point conversion) and his 10-yard TD pass to Burress, the Cowboys sealed the win with Romo completing a 51-yard TD pass to WR Sam Hurd. 
Question: How many TD's did Tony Romo have that was for longer than 20 yards?

[EX 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 
[EX A]: 6.

The Steelers struck first in the first quarter when Le'Veon Bell ran for a 5-yard touchdown to take a 7-0 lead. This would be followed by Ben Roethlisberger finding Antonio Brown on a 25-yard touchdown pass later on in the quarter to make it 14-0. The Colts got on the board in the second quarter when QB Scott Tolzien, starting in place of the injured Andrew Luck, found Donte Moncrief on a 5-yard touchdown pass to make it 14-7. However, the Steelers pulled away as Roethlisberger found Brown again this time on a 33-yard touchdown pass for a 21-7 lead at halftime. After a scoreless third quarter, the Steelers sealed the game with the only points in the second half when Roethlisberger found Brown again this time on a 22-yard touchdown pass and the eventual final score of 28-7. With the win, the Steelers improved to 6-5. Roethlisberger's record as a starter improved to 1-1 on Thanksgiving Day.
