Task: Question Answering
Input (English): Passage: Trying to snap a five-game losing streak, the Rams stayed at home for a Week 13 interconference duel with the Miami Dolphins. The Rams would welcome back Steven Jackson to the lineup after weeks of sitting out with a thigh injury. Jackson gave the Rams a good enough boost to strike first with a first possession field goal by Josh Brown from 23 yards. Brown would kick a 51-yard field goal to give the Rams a 6-0 lead. In the second quarter, the Dolphins responded as RB Ronnie Brown got a 3-yard TD run. The Rams would answer with Brown making a 33-yard field goal, but Miami replied with kicker Dan Carpenter getting a 37-yard field goal. In the third quarter, the Dolphins increased their lead as Carpenter got a 47-yard field goal. In the fourth quarter, St. Louis tried to keep up as Brown made a 38-yard field goal, yet Miami answered right back with Carpenter nailing a 42-yard field goal. The Rams tried to come back, but a late-game interception shattered any hope of a comeback. 
Question: How many more field goal yards did Josh Brown kick than Dan Carpenter? 
Answer type: Number
