Task: Question Answering
Input (English): Passage: Coming off their bye week, the 49ers flew to Reliant Stadium for a Week 7 interconference showdown with the Houston Texans. San Francisco would find itself trailing early in the first quarter as Texans running back Steve Slaton got a 1-yard touchdown. Houston would add onto their lead in the second quarter with quarterback Matt Schaub hooking up with Slaton on a 9-yard touchdown pass and finding tight end Owen Daniels on a 42-yard touchdown pass. For the second half, starting quarterback Shaun Hill (6/11 for 45&#160;yards) was benched due to poor performance and replaced with quarterback Alex Smith. It began to pay off in the third quarter as Smith completed a 29-yard touchdown pass to tight end Vernon Davis. In the fourth quarter, Smith and Davis would hook up with each other again on a 14-yard touchdown pass. However, the Texans answered with a 50-yard field goal from kicker Kris Brown. The Niners tried to rally as Smith found Davis again on a 23-yard touchdown pass, but that would be as close to a comeback that San Francisco would get as Houston's defense stiffened for the win. Wide receiver Michael Crabtree, in his NFL debut, would have 5 receptions for 56&#160;yards. 
Question: How many second quarter touchdown passes did Schaub have?
