Q: The Mongols' greatest triumph was when Kublai Khan established the Yuan dynasty in China in 1271. The Yuan dynasty created a "Han Army" out of defected Jin troops and an army of defected Song troops called the "Newly Submitted Army" . The Mongol force which invaded southern China was far greater than the force they sent to invade the Middle East in 1256. The Yuan dynasty established the top-level government agency Bureau of Buddhist and Tibetan Affairs to govern Tibet, which was conquered by the Mongols and put under Yuan rule. The Mongols also invaded Sakhalin Island between 1264 and 1308. Likewise, Korea became a semi-autonomous vassal state and compulsory ally of the Yuan dynasty for about 80 years. The Yuan dynasty was eventually overthrown during the Red Turban Rebellion in 1368 by the Han Chinese who gained independence and established the Ming dynasty.

Q: Coming off their easy road win over the Rams, the Vikings went home for a Week 6 inter-conference duel with the Baltimore Ravens. Minnesota got off to a fast start in the first quarter with quarterback Brett Favre completing a 19-yard touchdown pass to tight end Visanthe Shiancoe and a 4-yard touchdown pass to wide receiver Bernard Berrian. Afterwards, the Ravens got the only points of the second quarter as kicker Steven Hauschka getting a 29-yard field goal. In the third quarter, the Vikings picked up where they left off with a 40-yard field goal from kicker Ryan Longwell. Baltimore responded with a 22-yard touchdown run from running back Ray Rice, yet Longwell helped out Minnesota by nailing a 22-yard field goal. Afterwards, an action-packed fourth quarter ensued. Minnesota increased its lead with Favre hooking up with Shiancoe again on a 1-yard touchdown pass, but the Ravens continued to hang around as quarterback Joe Flacco found wide receiver Mark Clayton on a 32-yard touchdown pass. The Vikings replied with Longwell's 29-yard field goal, but Baltimore took lead for the first time in the game as Flacco hooked up with wide receiver Derrick Mason on a 12-yard touchdown pass and Rice running 33 yards for a touchdown. Minnesota then regained the lead as Longwell booted a 31-yard field goal after a 58-yard pass from quarterback Brett Favre to wide receiver Sidney Rice. The Ravens got a last-minute drive into scoring range, but Hauschka's 44-yard field goal attempt went wide left, preserving the Vikings' perfect season. With the win, the Vikings acquired their first 6-0 start since 2003 (unfortunately that team did not make the playoffs). Also, dating back to Week 17 of the 2008 season, Minnesota has won seven-straight regular season games for the first time since 2000.

Median house prices have increased by an average of 8.6% per annum since 1970. The median house price in Sydney in March 2014 was $630,000. The primary cause for rising prices is the increasing cost of land which made up 32% of house prices in 1977 compared to 60% in 2002. 31.6% of dwellings in Sydney are rented, 30.4% are owned outright and 34.8% are owned with a mortgage. 11.8% of mortgagees in 2011 had monthly loan repayments of less than $1,000 and 82.9% had monthly repayments of $1,000 or more. 44.9% of renters for the same period had weekly rent of less than $350 whilst 51.7% had weekly rent of $350 or more. The median weekly rent in Sydney is $450.
