Task: Question Answering
Input (English): Passage: Coming off their Monday night road win over the Redskins, the Eagles went home for a Week 8 NFC East duel with the New York Giants with the division lead on the line. Philadelphia came out soaring in the first quarter as fullback Leonard Weaver got a 41-yard touchdown run, followed by quarterback Donovan McNabb hooking up with tight end Brent Celek on a 17-yard touchdown pass (with a blocked PAT).  In the second quarter, the Eagles increased their lead as kicker David Akers nailed a 30-yard field goal.  The Giants would get on the board as quarterback Eli Manning found tight end Kevin Boss on an 18-yard touchdown pass, yet Philadelphia kept their momentum going as McNabb completed a 54-yard touchdown pass to wide receiver DeSean Jackson and a 23-yard touchdown pass to rookie wide receiver Jeremy Maclin. The Eagles would increase their lead in the third quarter as Akers booted a 35-yard field goal, yet New York attempted to rally as kicker Lawrence Tynes made a 42-yard field goal and running back Ahmad Bradshaw got a 1-yard touchdown run.  In the fourth quarter, Philadelphia pulled away with a 66-yard touchdown run by rookie running back LeSean McCoy. With the win, not only did the Eagles improve to 5-2, but they would take over as the leader of the NFC East.
