Task: Question Understanding
Input (English): Passage: The Steelers traveled to Chicago to take on the Bears. In the first quarter, the Bears scored first when Jordan Howard ran for a 3-yard touchdown to take a 7-0 lead for the only score of the quarter. In the second quarter, the Steelers managed to tie it up at 7-7 when Ben Roethlisberger found Antonio Brown on a 7-yard pass. The Bears moved ahead by double digits later on when Mike Glennon found Adam Shaheen on a 2-yard pass to make it 14-7. This would be followed up by Connor Barth's 24-yard field goal to make it 17-7 at halftime. After the break, the Steelers got back to work and came within 3 as Le'Veon Bell ran for a 1-yard touchdown to make it 17-14. They would tie the game up in the fourth quarter when Chris Boswell nailed a 32-yard field goal. The Steelers then tried their hand at coming back for the win later on in the quarter, but Roethlisberger was sacked in Bears territory, sending the game into overtime. In overtime, the Bears got the ball. They would win it by way of Howard's 19-yard run for a touchdown and the final score 23-17. With the loss and 9-game regular season winning streak snapped, the Steelers dropped to 2-1 and with the Ravens' loss to the Jaguars moved into a tie on top of the AFC North. The loss was the Steelers' third straight against the Bears, and dropped the Steelers to a record of 1-12 all-time against the Bears in Chicago.
