Task: Question Generation
Input (English): Passage: The Chargers host the Ravens in their home debut in San Diego after a narrow escape in the second of two AFL 50th Anniversary-themed division rivalry Monday Night matchups against the Raiders in Oakland. The Chargers jumped out to an early lead when a blown coverage led to an easy 81-yard touchdown pass from Philip Rivers to Darren Sproles. The Ravens answered with Willis McGahee on a 5-yard touchdown run, but the Chargers would increase their advantage on a Nate Kaeding field goal. The offensive display would continue in the second quarter, but the Ravens touchdowns were only answered by Chargers field goals. McGahee found the end zone a second time to take the lead 14 - 10, but the Chargers pulled within one on the second Kaeding field goal. Flacco then found Kelley Washington for Flacco's first touchdown pass of the day and Washington's first touchdown reception as a Raven just inside the 2-minute halftime warning. Rivers led the Chargers down the field in an attempt to answer, but the drive stalled and had to settle for the third of four Kaeding field goals. In the second half, both defenses stiffened. Todd Heap would get his second touchdown catch of the season from Flacco from 9 yards out, but the Chargers responded with a 35-yard touchdown catch from Vincent Jackson. Late in the fourth quarter, interceptions from Flacco and Rivers led to trading field goals. After a Ravens punt, Rivers led the Chargers all the way down to the Ravens 15. The Chargers went for the first down on fourth down to go for the win, but Sproles was stopped by Ray Lewis five yards in the backfield, allowing the Ravens to run the clock out. With the win, not only do the Ravens improve to 2-0, the Ravens take sole possession of first place in the AFC North with the Steelers' loss to the Bears.
Output (English): How many field goals did Nate Kaeding make in the second half?
