Task: Question Generation
Input (English): Passage: Hoping to rebound from their season-opening loss to the Jaguars, the Broncos played on home ground for an interconference duel with the Seattle Seahawks. In the first quarter, the Broncos took the early lead, as quarterback Kyle Orton completed a 13-yard touchdown pass to wide receiver Eddie Royal, followed in the second quarter by a 1-yard touchdown run from running back Correll Buckhalter and a 20-yard field goal by placekicker Matt Prater. The Seahawks got on the board in the third quarter, when quarterback Matt Hasselbeck completed an 11-yard touchdown pass to wide receiver Ben Obomanu, but the Broncos replied with a 1-yard touchdown run from running back Knowshon Moreno. The Broncos increased their lead in the fourth quarter, when Orton threw a 21-yard touchdown pass to wide receiver Demaryius Thomas. The Seahawks replied, with Hasselbeck scrambling 20 yards for a touchdown, but the Broncos' lead was too much for Seattle to overcome.
Output (English): How many yards was the longest touchdown pass?
