Problem: Coming off their win over the Bears, the Broncos returned home for an AFC duel with the New England Patriots on NBC's Sunday Night Football, on a snowy night in Denver. The Patriots, who entered the game with a 10-0 record, jumped out to a 14-0 lead, with quarterback Tom Brady tossing two touchdown passes &#8212; a 23-yarder to tight end Rob Gronkowski, followed in the second quarter by a 10-yarder to tight end Scott Chandler. The latter score occurred after Broncos' quarterback Brock Osweiler had a pass deflected and intercepted deep in Broncos' territory. The Broncos got on the scoreboard just before the two-minute warning, with running back Ronnie Hillman rushing for a 19-yard touchdown. The Broncos had a chance to cut into the Patriots' lead on their first possession of the second half, however, placekicker Brandon McManus missed wide-right on a 47-yard field goal attempt. Each team proceeded to trade punts on their next two offensive possessions, until Brady connected with wide receiver Brandon Bolden on a 63-yard touchdown pass at the beginning of the fourth quarter to give the Patriots a 21-7 lead. The Broncos' offense went three-and-out, and were forced to punt. However, Patriots' return specialist Chris Harper muffed the punt, which was recovered by Shaquil Barrett at the Patriots' 36-yard line, giving the Broncos new life. Four plays later, the Broncos pulled to within a one-touchdown deficit, with a 15-yard touchdown run by running back C. J. Anderson. The Broncos' defense forced a punt on the Patriots' next possession, which was aided by an offensive holding penalty on guard Tre' Jackson that nullified a 51-yard pass completion from Brady to wide receiver Keshawn Martin on a third-and-long play. The Broncos then marched down the field, but had to settle for a 21-yard field goal by McManus to pull to within 21-17 with 6:12 remaining in the fourth quarter. The two teams traded punts on their next possessions, and with 2:39 remaining and no timeouts, the Broncos forced a Patriots' punt. The Broncos marched down the field and were facing a 2nd-and-goal from the Patriots' 7-yard line, when Osweiler was sacked for an eight-yard loss. However, the sack was nullified by a defensive holding penalty on Patriots' safety Patrick Chung. On the very next play, the Broncos grabbed their first lead of the game, when Osweiler connected with wide receiver Andre Caldwell on a 4-yard touchdown with 1:15 remaining in the fourth quarter. The Patriots were not done yet, as Brady engineered a 5-play, 51-yard drive, which culminated with placekicker Stephen Gostkowski kicking a game-tying 47-yard field goal as time expired, sending the game to overtime. The Patriots won the overtime coin toss, but their offense went three-and-out. Following a Patriots' punt, the Broncos started their first overtime drive at their own 43-yard line, and three plays later, Anderson scampered down the sideline for a game-winning 48-yard touchdown run.

Problem: Contemporary documents show that the British continued the physical occupation of Chumbi Valley until February 8, 1908, after having received the full payment from China. In early 1910, Qing China sent a military expedition of its own to Tibet for direct rule. However, the Qing dynasty was overthrown in the Xinhai Revolution, which began in October 1911. Although the Chinese forces departed once more in 1913, the First World War and the Russian Revolution isolated the now independent Tibet, reducing Western influence and interest.  Ineffectual regents ruled during the 14th Dalai Lama's infancy and China began to reassert its control, a process that culminated in 1950-1951 with the Chinese invasion of Tibet by a newly-formed Communist China. The position of British Trade Agent at Gyangzê was occupied from 1904 until 1944. It was not until 1937, with the creation of the position of "Head of British Mission Lhasa", that a British officer had a permanent posting in Lhasa itself. The British seem to have misread the military and diplomatic situation, for the Russians did not have the designs on India that the British imagined, and the campaign was politically redundant before it began. Russian arms in Tibet amounted to no more than thirty Russian government rifles, and the whole narrative of Russian influence, and the Czar's ambitions, was dropped. The defeats the Russians experienced in the Russo-Japanese war that began in February 1904 further altered perceptions of the balance of power in Asia, and the Russian threat. However, it has been argued that the campaign had "a profound effect upon Tibet, changing it forever, and for the worse at that, doing much to contribute to Tibet's loss of innocence."
