Task: Question Understanding
Input (English): Passage: Hoping to rebound from their tough home loss to the Giants, the Cardinals flew to Lincoln Financial Field for a Week 13 Thanksgiving battle with the Philadelphia Eagles. In the first quarter, Arizona trailed early as Eagles QB Donovan McNabb completed a five-yard TD pass to RB Brian Westbrook, while Westbrook got a one-yard TD run. In the second quarter, the Cardinals continued to trail as McNabb hooked up with Westbrook again on a two-yard TD pass. The Cardinals would respond as QB Kurt Warner completed a one-yard TD pass to WR Larry Fitzgerald. Philadelphia would close out the half with kicker David Akers making a 42-yard field goal. In the third quarter, Arizona's struggles continued as Westbrook got a nine-yard TD run. The Cardinals would answer with Warner completed a six-yard TD pass to WR Steve Breaston (with a failed two-point conversion.) The Eagles would reply as Akers got a 41-yard field goal. In the fourth quarter, the Cardinals tried to rally as Warner hooked up with Fitzgerald again on a seven-yard TD pass. However, Philadelphia replied with McNabb completing a 5-yard TD pass to WR DeSean Jackson, along with an eight-yard TD pass to WR Jason Avant.
Question: How many more yards was McNab's fourth touchdown over his third?
