Task: Question Answering
Input (English): Passage: The Raiders traveled to Tennessee looking to shore up their defense that had allowed 500 yards in each of the first two games of the season. The defense responded, forcing three Titan turnovers and holding the Titans to only one touchdown and 393 yards of offense on the day. Latavius Murray scored a touchdown for the third consecutive game, giving the Raiders a lead on their first drive, jumping in front of the Titans 7-3. The Raiders took over in the second quarter, scoring a touchdown on a 19-yard pass from Derek Carr to Seth Roberts and on Sebastian Janikowski's record-setting 52-yard field goal which marked the most field goals over 50 yards by any one player. Titans quarterback, Marcus Mariota, was intercepted on the final play of the first half by Reggie Nelson and the Raiders took a 17-3 halftime lead. DeMarco Murray brought the Titans within seven in the third quarter, scoring on a five-yard run. The Raiders defense held strong for the rest of the half, intercepting Mariota again late in the third quarter. However, the Raiders offense mustered zero points in the second half and, as a result, the Titans had a chance to tie the game late in the fourth quarter. Mariota hit Tajae Sharpe to get to the Raiders three-yard line with just over a minute remaining. However, Titan offensive lineman Taylor Lewan was called for unnecessary roughness for jumping on the pile after the play. The Titans were pushed back 15 yards, but Mariota hit Andre Johnson two plays later for an apparent touchdown, but Johnson was called for pass interference on the play and the touchdown was taken off the board. On fourth down with 16 seconds remaining, Mariota could not hit Harry Douglas in the endzone and the Raiders pulled out the victory. The win moved the Raiders to 2-1 on the season.
