Task: Question Understanding
Input (English): Passage: David Carr threw for 167 yards and ran for 48 more, and the Texans defeated the Jaguars 13-10 to snap a 12-game road losing streak. The Texans upset their AFC South rivals for the second time in four weeks and won on the road for the first time since December 2004. David Garrard, making his third consecutive start in place of Byron Leftwich, was intercepted four times. Two came after Matt Jones bobbled perfect passes. Ernest Wilford also dropped two balls, including a deep one that could have been a touchdown. Carr directed a 70-yard drive to start the game and had two key runs. Wali Lundy scored from 1 yard, then Houston took advantage of Garrard's first turnover to make it 10-0. DeMeco Ryans pressured Garrard and forced a floater over the middle. Morlon Greenwood picked it off, setting up Kris Brown's 25-yard field goal.
