Task: Question Answering
Input (English): Passage: After winning in a close game at home, the Steelers traveled to Cincinnati for Game 2 against the Bengals. The Bengals scored first in the first quarter when Randy Bullock kicked a 35-yard field goal to make it 3-0. They would then make it 10-0 when Andy Dalton found A.J. Green on an 8-yard pass. In the second quarter, Dalton and Green connected again on a 15-yard pass to make it 17-0. The Steelers managed to get on the board before halftime when Chris Boswell put a 30-yard field goal through to make the score 17-3. In the third quarter, the Steelers drew closer when Ben Roethlisberger found Le'Veon Bell on a 35-yard touchdown to make it 17-10. The Bengals moved back ahead by double digits when Randy Bullock kicked a 31-yard field goal to make it 20-10. In the fourth quarter, it was all Steelers when Boswell put up a 37-yard field goal to make it 20-13. Roethlisberger then found Antonio Brown on a 6-yard pass to tie the game up at 20-20. Finally, Boswell was able to seal the victory with a 38-yard field goal to make the final score 23-20. With their sixth straight win over the Bengals, the Steelers improved to 10-2. The victory marks the third time that the Steelers have recorded two different 7+ win streaks within consecutive and separate regular seasons (1975-76, 1994-95). The team also won their 8th straight game against a divisional opponent. With the win, the Steelers began 4-0 in their division for the first time since 2008. The 17-point comeback was the Steelers' largest since they came back from down 17 on December 20, 2015 against the Denver Broncos, and their largest on the road since their 21-point comeback on October 5, 1997 against the Baltimore Ravens.
