Task: Question Answering
Input (English): Passage: The Texans' offense was forced into five consecutive three-and-outs in the 1st quarter, while the Dolphins' offense scored three passing touchdowns, two of which came from at least 50 yards. After a lopsided first quarter, the Texans trailed the Dolphins 0-21. The 2nd quarter didn't start off any better for Houston, with Ryan Tannehill connecting with Lamar Miller for a 54-yard touchdown reception. With Andrew Franks making the extra point, Miami extended their lead to 28-0. The Texans sunk even lower on their next possession, with a Brian Hoyer pass being intercepted by Reshad Jones, who returned it for a touchdown. With the pick-six, the Dolphins further extended their lead to 35-0 early in the 2nd. With 7:45 left in the 2nd quarter, the Texans finally picked up their first 1st down. Finally getting into the redzone for the first time of the day, Houston turned the ball over on downs on 4th and 2. Miami answered with an 85-yard rush from Miller to extend their lead to 41-0. The score stuck going into halftime, with the Texans facing their largest halftime deficit in franchise history. Early in the 3rd quarter, Miami fumbled the ball which was recovered by Houston defender Johnathan Joseph. The fumble recovery set up the Texans' first score of the day, with Hoyer connecting with Arian Foster. With Nick Novak missing the extra point, Houston trailed Miami 6-41 with 8:13 left in the 3rd. Foster scored again late in the 3rd, this time with a 2-yard rush. With Novak's kick good, the Texans trailed 13-41 with 1:45 left in the 3rd quarter. Houston scored again early in the 4th quarter, with Hoyer connecting with Nate Washington for a 27-yard touchdown pass. With Novak's kick good, the Texans trailed 20-41 after scoring 20 unanswered points. Miami got their first points of the 2nd half midway through the 4th, with Franks making a 53-yard field. The field goal extended the Dolphins' lead to 44-20 with 7:46 left to play. Hoyer found Washington again for a 5-yard touchdown pass. With the 2-point conversion no good, the Texans trailed 26-44 with 4:00 left to play. The Texans fell to the Dolphins 44-26, their first loss to the Dolphins in franchise history. With the loss, Houston dropped to 2-5 on the season. Arian Foster left the game with an Achilles tear in the 4th quarter; it was later announced that Foster would miss the rest of the season. Backup quarterback Ryan Mallett was cut from the team 2 days after the game. Mallett had missed the team's charter flight to the game and was late to a team meeting the day before. Former Texans backing quarterback T. J. Yates was named as Mallet's replacement.
