Task: Question Answering
Input (English): Passage: The Jets got off to a sloppy start when Raiders rookie starting QB Derek Carr torched the Jets defense early in the game to take a 7-3 lead after Charles Woodson picked off Jets 2nd year QB Geno Smith in his 17th start. However, the Jets quickly rebounded with a 5-yard shovel TD pass from Smith to Chris Johnson to take the lead 10-7 going into halftime. The Jets would never trail the rest of the game, although Carr threw a late TD pass to Raiders WR James Jones in garbage time, and attempted a failed onside kick. Chris Ivory had a solid day, rushing for 102 yards and a TD. The score came when Ivory ran 71 yards for a TD during the 4th quarter; it was the Jets' longest TD run since Thomas Jones 71-yard TD run back in October 19, 2009. Geno Smith completed a career-best 82.1% completion percentage (23/28 for 221 yards, 1 TD, 1 INT); it was the best performance delivered by a Jet quarterback since Chad Pennington completed 82.1% of his passes in a loss to the Buffalo Bills way back in 2007. 
Question: How many points did The Jets lead by at halftime?
