Task: Question Answering
Input (English): Passage: Coming off their divisional home win over the Panthers, the Saints flew to the Edward Jones Dome for a Week 10 duel with the St. Louis Rams. After a scoreless first quarter, New Orleans got the game's inaugural points in the second quarter with running back Reggie Bush getting a 3-yard touchdown run. The Rams would respond with quarterback Marc Bulger completing a 29-yard touchdown pass to wide receiver Donnie Avery. New Orleans would answer with quarterback Drew Brees hooking up with Bush on a 15-yard touchdown pass, yet St. Louis would close out the half with a 2-yard touchdown run from running back Steven Jackson. The Saints would begin the third quarter with wide receiver Courtney Roby returning the second half's opening kickoff 97 yards for a touchdown. The Rams would stay close with kicker Josh Brown nailing a 32-yard field goal. New Orleans would extend their lead in the fourth quarter Brees finding wide receiver Robert Meachem on a 27-yard touchdown pass. St. Louis tried to catch up as Bulger found Avery again on a 19-yard touchdown pass (with a failed 2-point conversion), yet the defense prevented the Rams from getting any closer. 
Question: How many is the difference in the number of yards of Bush's TD run and the number of yards of the second pass to Avery? 
Answer type: Number 
Output (English): 16.
