Task: Question Answering
Input (English): Passage: The Texans hosted the 1-1 Buccaneers at home, looking for their first win of the 2015 season. Both Houston and Tampa Bay punted the ball on their first possession, before Houston scored first with Ryan Mallett connecting with DeAndre Hopkins for a 5-yard touchdown pass. With Randy Bullock's extra point good, the Texans took a 7-0 lead with 4:58 left in the first quarter. Tampa Bay managed to get on the board with their first possession of the 2nd quarter, with Kyle Brindza making a 58 yard long field goal to trail 3-7. Both teams punted on their next possession, with the Texans committing the first turnover of the day with a Ryan Mallett pass being intercepted by Kwon Alexander. The Buccaneers capitalized on the turnover in just 50 seconds, with Jameis Winston throwing a 32-yard pass to Charles Sims. With Brindza missing the extra point, Tampa Bay lead Houston 9-7 with 3:51 left in the half. Receiving the ball back, Bullock missed a 43-yard field goal. Tampa Bay received the ball to start the 2nd half, however Winston threw an interception that was caught by Quintin Demps. The Texans settled for 3 points off the turnover with Bullock making a 34-yard field goal. The kicking problems continued for the Buccaneers after Brindza missed a 41-yard field goal with 7:21 left in the 3rd, then again from 33 yards with 10:56 left to play. Following another missed field goal for Tampa Bay, Houston went 77 yards in just 5 plays to score a touchdown with an Alfred Blue 20 yard rush. With Bullock missing his 2nd extra point attempt of the season, the Texans extended their lead to 16-9 with 9:19 left to play. The Texans extended their lead with a 19-yard field goal from Bullock to lead 19-9 with 1:15 left to play. With Brindza missing his 3rd field goal of the day (this time from 57 yards), the Texans held on to secure their first win of the season. The Buccaneers were completely shut out during the second half while the Texans scored 12 unanswered points.
