question:
Passage: The Hotak dynasty  was an Afghan monarchy of the Ghilji Pashtuns, established in April 1709 by Mirwais Hotak after leading a successful revolution against their declining Persian Safavid overlords in the region of Loy Kandahar  in what is now southern Afghanistan. It lasted until 1738 when the founder of the Afsharid dynasty, Nader Shah Afshar, defeated Hussain Hotak during the long siege of Kandahar, and started the reestablishment of Iranian suzerainty over all regions lost decades before against the Iranian archrival, the Ottoman Empire, and the Russian Empire. At its peak, the Hotak dynasty ruled briefly over an area which is now Afghanistan, Iran, western Pakistan, and some parts of Tajikistan and Turkmenistan. In 1715, Mirwais died of a natural cause and his brother Abdul Aziz succeeded the monarchy. He was quickly followed by Mahmud who ruled the empire at its largest extent for a mere three years. Following the 1729 Battle of Damghan, where Ashraf Hotak was roundly defeated by Nader Shah, Ashraf was banished to what is now southern Afghanistan with Hotak rule being confined to it. Hussain Hotak became the last ruler until he was also defeated in 1738.

Passage: The Cowboys' tenth game was an NFC duel with the Lions. In the first quarter the Cowboys pulled ahead with QB Jon Kitna making a 1-yard TD pass to WR Dez Bryant. The Lions replied with kicker Dave Rayner nailing a 47-yard field goal. The Cowboys trailed with QB Shaun Hill making a 9-yard TD pass to WR Nate Burleson, followed by a Penalty on Leonard Davis which was enforced to the endzone for a safety. The Cowboys got the lead back with DB Bryan McCann returning a punt 97 yards for a touchdown, which was followed by Kitna making a 3-yard TD pass to WR Miles Austin. The lead was narrowed with Hill completing a 14-yard TD pass to WR Calvin Johnson. The Cowboys increased their lead with Kitna finding Austin again on a 4-yard TD pass, followed by Kitna's 29-yard scramble to the endzone for a touchdown, which was his longest run of his career. Cowboys interim coach Jason Garrett won his home debut and improved to 2-0 since taking over for Wade Phillips. It's the first time this season Dallas (3-7) has won consecutive games and the first time all season it won at home, having lost the first four.The Lions (2-8) lost their 26th straight on the road, extending a woeful NFL record that began in 2007, when Kitna was their quarterback.Detroit led 12-7 and was consistently stuffing the Cowboys' offense midway through the third quarter when John Wedling jumped over the goal line and tapped a punt back into the field of play.It hopped up waist-high and right to McCann, and the speedster turned it into the second-longest punt return in franchise history - a week after a 101-yard interception return that was the longest in club history. With the win the Cowboys improved to 3-7 on the season.
