[EX Q]: Passage: The Ravens were facing the Tampa Bay Buccaneers, a team with an identical 7-3 record. However, the Ravens were considered favorites going into the game, given that they had never lost at home during the season, and all Tampa Bay wins were against teams with losing records. Still, they did not take this one lightly. After a scoreless first quarter, the Ravens scored first with a field goal. Tampa Bay later tied it, but Baltimore scored two touchdowns, including one on a 65-yard pass from Todd Heap, to have a 17-3 halftime lead. During a scoreless third quarter, a would be long TD-run from Ray Rice was negated by a controversial call of a penalty on Anquan Boldin. Though the Ravens would never score anymore in the game, they managed to hold off Tampa Bay and allow just one touchdown, enough to prevent their lead from being blown.

[EX Q]: Passage: The Buccaneers stayed home this week for a rematch against their division rivals the Atlanta Falcons. With the convincing victory, Tampa Bay clinched the NFC South division title, maintained a perfect 5-0 division record, and scored their first kickoff return touchdown in franchise history. Tampa Bay's defense recorded the first points of the game, as Ronde Barber intercepted Chris Redman's pass on the third play of the game and returned it 29 yards for a touchdown. Atlanta got on the board next with kicker Morten Andersen making a 33-yard field goal. On the ensuing kickoff, Micheal Spurlock made team history by becoming the first Buccaneer player to return a kickoff for a touchdown. It was the first kickoff return touchdown for Tampa Bay in 32 seasons, 498 games, and 1,865 attempts. After the Buccaneer defense forced a Falcons punt, Jeff Garcia commandeered a long, clock-eating 10-minute drive ending in a 33-yard field goal by Matt Bryant to make the score 17-3. With just over five minutes remaining in the first half, Tampa bay recovered an Atlanta fumble, and Earnest Graham scored a 1-yard TD run. Graham became the first player in club history to score a touchdown in six consecutive games. With a 24-3 lead, Tampa Bay performed a pooch kickoff, and Atlanta muffed the return, while Kalvin Pearson recovered. Tampa Bay drove to the 24-yard line, but DeAngelo Hall intercepted a pass intended for Joey Galloway at the Atlanta 11-yard line. The Buccaneers would immediately regain possession as Greg White forced and recovered a fumble on the next play. Matt Bryant then easily converted a 28-yard field goal to take a 27-3 lead into halftime. Tampa Bay would receive the second half's opening kickoff, but was forced to punt after a 7-minute drive. On Atlanta's third play, Jermaine Phillips intercepted a pass intended for Jerious Norwood which set Tampa Bay up at the Atlanta 23-yard line. Matt Bryant then scored the half's first points with a 34-yard field goal to make the score 30-3. In the fourth quarter, punter Josh Bidwell successfully pinned Atlanta at their own 6-yard line. The resulting poor field position eventually led to Tampa Bay taking over near midfieldied Michael Bennett carried six times all the way to the Atlanta 1-yard line, from which Anthony Becht scored the game's final points off a 1-yard TD catch. Statistically, Tampa Bay's defense dominated Atlanta. The Falcons managed only 133 yards of total offense, committed five turnovers, and were 0-for-9 on third down conversions. The Falcons crossed midfield only once, and Tampa Bay's time of possession was 43 minutes. On the following Wednesday, the kickoff return touchdown earned Spurlock the NFC Special Teams Player of the Week award.

[EX Q]: 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".
