question: In week 15, the Lions hosted the defending the NFC Champion Arizona Cardinals. The first half was all Arizona. First was a Larry Fitzgerald 1-yard catch from Kurt Warner. Next in the second quarter a 48-yard field goal by Mike Nugent. Then near halftime a 1-yard rush by Tim Hightower. After his unproductive first half (6 for 12 and only 64 yards passing and an interception) Lions backup quarterback Daunte Culpepper was replaced by third stringer Drew Stanton who breathed some life into the offense. First though came an interception and 100 yard Lions TD run by Louis Delmas, a tie for the third longest interception TD in team history. A few minutes later Detroit's Maurice Morris ran in a career-high 64 yard TD.  In the 4th quarter, the Cardinals responded with an 18-yard Chris Wells TD run. The Lions tied it back up when Stanton ran in his first career rushing TD from 1 yard out. The Cardinals sealed their victory though with just under 2 minutes left when Anquan Boldin caught a 5-yard TD pass. The Lions attempted to tie it back up soon after but were stopped on 4th and 1.
Answer this question: How many times did Arizona score in the first half?
answer: 3

question: Coming off their bye week, the Redskins stayed at home for a Week 5 duel with the Detroit Lions. The Lions at that time had never beaten the Redskins in Washington, D.C. Though the first quarter was scoreless, the Redskins began what would be a 14-play 80-yard drive in the second quarter that finished with a 7-yard touchdown pass from Jason Campbell to Chris Cooley. The Redskins' next possession began at their own 17-yard line: in summary, an 83-yard drive in 7 plays, culminating in a touchdown for Mike Sellers in a 1-yard rushing play. The first half ended with the Redskins up, 14-0. With 2:27 left in the third quarter, the Lions scored their first and only points with a 39-yard field goal to bring the score to 14-3. The Redskins' next drive was only 9 yards and resulted in a  punt, but put the Lions on their own 8-yard line. After a rushing play that resulted in a loss of 1 yard, the Redskins sacked Lions' quarterback Jon Kitna in the end zone for a safety, increasing the Redskins' lead to 13 with a score of 16-3 to end the third quarter. After a fourth-quarter fumble by Redskins' running back Clinton Portis, the Lions took possession at their own 10-yard line. The Lions drove 26 yards before punting to James Thrash, who returned the punt for 62 yards and fumbled towards the end zone, where Rock Cartwright recovered the ball on the 3-yard line. After a Redskins' five-yard penalty, Redskins quarterback Jason Campbell threw an 8-yard touchdown pass to Mike Sellers and then converted a two-point attempt with a pass to Chris Cooley bringing the score to 24-3. Detroit's next possession ended with an interception by safety Sean Taylor for a 35-yard return which would later help the Redskins finish a drive with a field goal. With less than 3 minutes in the fourth quarter, the Lions began a drive at their own 43-yard line. After gaining 14 yards, Jon Kitna threw an interception to cornerback Carlos Rogers, who returned it 61&#160;yards for a touchdown for the final score of the game.
