Passage: Week ten featured the Bears attempting to avoid suffering the first sweep by the Lions since 2007, while also trying to claim the division lead; the last time the two teams faced each other in a late-season game for the division lead was in 1991, which ended in a Chicago 20-10 win. However, the Bears had won the last five games against the Lions at Soldier Field. On November 7, Marc Trestman announced that Jay Cutler has been cleared by doctors to return against Detroit, despite having been projected to be out for approximately four weeks. Against the Lions, Cutler was 7-2, and won all four home games. On the offensive side, Jeff Joniak states that the Lions defensive line "are ferocious up the middle, they are physical, and they make you pay for poor technique," but that "there is growing confidence that the Bears offense is a resilient one;" the Bears had the fewest pre-snap penalties in the league, and only one false start. The Bears could also seize the Lions' cornerback corps, which struggled during the season, allowing 11 plays of 40 yards or more, along with 4.7 yards per carry. Defensively, Sports Illustrated writers Chris Burke and Doug Farrar wrote the Bears must attempt to hinder Reggie Bush, and improve their performance from the previous week, when the Packers' running game ran for 190 yards and two touchdowns. The Bears also had to prevent Calvin Johnson from excelling; against the Dallas Cowboys, Johnson recorded 329 receiving yards. Chicago scored first after Cutler's 32-yard touchdown pass to Brandon Marshall capped a 65-yard drive that took just 2:23. However, the Lions would travel 85 yards to tie on Matthew Stafford's 5-yard pass to Kris Durham. In the following quarter, the Bears reached the Lions' 4-yard line, but Cutler's pass was tipped by Ndamukong Suh, and intercepted by DeAndre Levy in the endzone; both teams would fail to score in the quarter. During the quarter, Cutler began showing signs of struggling due to an ankle injury. In the third quarter, the Lions would score on Stafford's four-yard touchdown to Johnson. Afterwards, the Bears were forced to settle for a 25-yard field goal, narrowing the gap to one point. In the fourth, Stafford was intercepted by Chris Conte, who reached Detroit's 9-yard line, and Cutler would then throw a 14-yard touchdown pass to Alshon Jeffery, which was eventually nullified. After an incomplete pass, Gould kicked a 32-yard field goal to draw the score to 14-13. However, Johnson would catch a 14-yard pass from Stafford to increase the lead to 21-13, and with 2:22 remaining, Josh McCown entered the game in favor of Cutler, and guided the Bears' offense 74 yards, culminating in McCown's 11-yard touchdown pass to Marshall with 40 seconds to go. On the two-point conversion, McCown's pass to tight end Dante Rosario fell incomplete, but Willie Young was penalized for roughing the passer, allowing the Bears a second chance, which failed after Matt Fort&#233; was tackled by Nick Fairley in the backfield. The Bears' onside kick would backfire, as Joique Bell recovered, sealing a season sweep for the Lions. Despite stating he was "100 percent" healthy after the groin injury suffered two games prior, it appeared the injury was still lingering; after throwing a pass during the third quarter, Cutler fell down and grabbed his groin, before standing back up.  Regarding the injuries, Cutler stated, "It held up OK. It's all on the same leg so I think that was a problem. But the groin, you take the ankle out of the equation and I would have been fine, I think." Cutler ended the game having completed 21 of 40 passes for 250 yards with a touchdown, interception and a 69.8 passer rating. Despite x-rays on his ankle being negative, Cutler was ruled out of the next week's game against the Baltimore Ravens with a high ankle sprain. During the second quarter, Charles Tillman was also injured, suffering a torn right triceps brachii muscle, and was placed on injured reserve with the designation to return, allowing him to practice after six weeks and play in games two weeks after; as a result, Tillman missed the entire regular season.

Passage: The size of the indemnity had been the hardest factor to accept for the Tibetan negotiators. The Secretary of State for India, St John Brodrick, had in fact expressed the need for it to be "within the power of the Tibetans to pay" and given Younghusband a free hand to be "guided by circumstances in this matter". Younghusband raised the indemnity demanded from 5,900,000 to 7,500,000 rupees, and further demanded the right for a British trade agent, based at Gyantse, to visit Lhasa "for consultations". It seems that he was still following Lord Curzon's geo-political agenda to extend British influence in Tibet by securing the Chumbi Valley for Britain.  Younghusband wanted the payment to be met by yearly instalments; it would have taken about 75 years for the Tibetans to clear their debt, and since British occupation of the Chumbi valley was surety until payment was completed, the valley would remain in British hands. Younghusband wrote to his wife immediately after the signing; "I have got Chumbi for 75 years. I have got Russia out for ever". The regent commented that "When one has known the scorpion  the frog  is divine". The Amban later publicly repudiated the treaty, while Britain announced that it still accepted Chinese claims of authority over Tibet. Acting Viceroy Lord Ampthill reduced the indemnity by two-thirds and considerably eased the terms in other ways. The provisions of this 1904 treaty were revised in the Anglo-Chinese Convention of 1906. The British, for a fee from the Qing court, also agreed "not to annex Tibetan territory or to interfere in the administration of Tibet", while China engaged "not to permit any other foreign state to interfere with the territory or internal administration of Tibet".

Passage: While KSCB was abandoned, the Marines continued to patrol the Khe Sanh plateau, including reoccupying the area with ARVN forces from 5-19 October 1968 with minimal opposition. On 31 December 1968, the 3rd Reconnaissance Battalion was landed west of Khe Sanh to commence Operation Dawson River West, on 2 January 1969 the 9th Marines and 2nd ARVN Regiment were also deployed on the plateau supported by the newly established Fire Support Bases Geiger and Smith; the 3-week operation found no significant PAVN forces or supplies in the Khe Sanh area. From 12 June to 6 July 1969, Task Force Guadalcanal comprising 1/9 Marines, 5th Infantry Regiment (United States) and 2nd and 3rd Battalions, 2nd ARVN Regiment occupied the Khe Sanh area in Operation Utah Mesa. The Marines occupied Hill 950 overlooking the Khe Sanh plateau from 1966 until September 1969 when control was handed to the Army who used the position as a SOG operations and support base until it was overrun by the PAVN in June 1971. The gradual withdrawal of US forces began during 1969 and the adoption of Vietnamization meant that, by 1969, "although limited tactical offensives abounded, US military participation in the war would soon be relegated to a defensive stance.".
