Teacher: Now, understand the problem? Solve this instance: Question: Where was Lake Minchin located? Passage 1:Lake Minchin was a saltwater lake, which covered the basins of the Salar de Uyuni, Salar de Coipasa, Lake Poopo and Salar de Empexa, including the towns of Llica, Oruro and the Desaguadero River valley. The lake had an extension of in east-west direction and of in north-south direction. A sill at Ulloma separated Lake Minchin from Lake Titicaca. Water levels reached an altitude of above sea level, indicating a depth of above the Uyuni basin. In the Poopo basin, water levels may have reached . At Cerro Lipillipi terraces between are dated between 25,700 and 31,750 BP. Another estimate is . Earlier estimates of the altitude are , resulting in depths of . Such water heights exceed these of preceding lakes, and together with even higher water levels of the subsequent Lake Tauca they are part of a trend of increasing water levels in the southern Altiplano which contrasts with progressively decreasing lake levels in the northern Altiplano. Earlier research suggested an opposite trend of lowering water levels in both basins. The surface area of Lake Minchin may have been , or . A lake terrace at is also attributed to Lake Minchin. The highest lake terraces at and were later found to belong to Lake Tauca, making it the deeper of the two lakes. If Minchin reached a water level of it may have spilled into the Pilcomayo River, draining from there via the Rio de la Plata into the Atlantic Ocean. It is also possible that the lake temporarily drained into the Pacific Ocean through its southwesternmost sector at Salar de Ascotan; such an outlet would have existed for only a brief time, however, before it was obstructed by volcanism. San Agustin, San Cristobal and Colcha formed islands in the lake, which was separated into a Coipasa half and an Uyuni half by a peninsula of the Serrania Intersalar; straits at Llica and Salinas de Garci Mendoza connected the two halves. Bays developed close to Isluga, Empexa and Ollague.
Passage 2:On June 25, 2010, during the 2010 NHL Entry Draft, Ballard was traded to the Vancouver Canucks (along with Victor Oreskovich) in exchange for Michael Grabner, Steve Bernier and Vancouver's first-round pick, the 25th overall selection ultimately used to select Quinton Howden. After spending two months of the off-season on crutches while recovering from surgery, he reported to the Canucks' training camp, but struggled in the pre-season. Four games into the regular season, he suffered a concussion after being hit into the boards by Los Angeles Kings forward Brad Richardson on October 16, 2010. He was subsequently sidelined for five games. However, upon returning to the lineup, his play continued to struggle. Averaging 13 minutes of ice time a game, he was eventually taken out of the lineup for four games in November by Canucks head coach Alain Vigneault. It marked the first time in his career he was a healthy scratch. After being re-insterted into the lineup, he scored his first goal as a Canuck in a 61 win against the San Jose Sharks on November 26. Several months later, Ballard suffered a sprained medial collateral ligament (MCL) in his right knee during a game against the Ottawa Senators on February 7, 2011. The injury resulted from opposing forward Milan Michalek tripping him from behind, which Canucks general manager Mike Gillis pointed out did not occur anywhere near the puck, alluding to the play as illegal and disrespectable. Ballard finished his first regular season with career lows in games played (65), goals (2), assists (5), points (7) and average ice time per game (15 minutes and 14 seconds). His individual struggles came amidst a franchise record season for the Canucks, who won the Presidents' Trophy as the NHL's regular season champion for the first time in team history. Entering the playoffs as the first seed in the West, the Canucks advanced past the Chicago Blackhawks, Nashville Predators and San Jose Sharks to qualify for the 2011 Stanley Cup Finals. Facing the Boston Bruins, Vancouver lost the Stanley Cup in Game 7. Over the team's 25 playoff games, Ballard dressed for 10. Playing only one game of the final two rounds, he dropped in the depth chart behind Aaron Rome and rookie Chris Tanev.
Passage 3:Ashraf Rashid joined in the Pakistan Army in 1964 and had participated in Indo-Pakistani War of 1965 as a junior non-commissioned officer (JNCO). Rashid entered the Pakistan Military Academy in 1966. He graduated two years later and joined the Pakistan Army at the rank of lieutenant.

Rashid graduated from the Command and General Staff College in Fort Leavenworth, Kansas. He served in the Indo-Pakistani War of 1971 and participated in the conflict as a captain, during which he was permanently injured on the right cheek. As a special service officer, Rashid was promoted as a Brigadier-General and was later sent to Siachen where he along with then-Brigadier-General Parvez Musharraf, participated in the conflict. In 1995, he was promoted as a major-general and was made commandant of his unit. He was an instrumental for conducting paramilitary operations and infiltrating Kashmiri militants in the Kargil War.
