In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: On 6 September 1950, an isolated and exhausted platoon of the 24th Infantry Division is cut off. In addition to losing radio contact, the platoon is harassed by unseen North Korean infiltrators who silently kill the Americans and take their weapons. Platoon leader Lieutenant Benson has only vague instructions to reach a certain hill to link up with American forces.
The patrol stops a jeep driven by Staff Sergeant "Montana" (Aldo Ray) and shell shocked passenger "the Colonel" (Robert Keith) from the First Cavalry Division. The Colonel is unable to speak and is tied to his seat. After the Battle of the Nakdong River, where "our men fell like rain", the tough experienced Montana decided he and his Colonel, whom he treats like his father, have had enough of the war. Benson commandeers their jeep for his platoon's equipment and the battle-fatigued Corporal Zwickley.
The platoon makes its way towards the hill. Montana disobeys Benson by instinctively shooting a surrendering North Korean sniper, who turns out to have a concealed weapon inside his hat. Sergeant Killian is killed while covering the rear after absentmindedly filling his helmet net with flowers. Montana takes his place and feigns fatigue, luring the infiltrators into the open, where he kills them.
The cynical Montana transforms the platoon back into a military formation while also curing Zwickley's neurosis by slapping him around. The platoon successfully carries on through sniper attack, artillery barrage, and land mines during which Platoon Sergeant Lewis panics and is killed.

Answer: What are the nicknames of the people who have their jeep commandeered?

Question: Passage: Washington, D.C. is located in the mid-Atlantic region of the U.S. East Coast. Due to the District of Columbia retrocession, the city has a total area of 68.34 square miles (177.0 km2), of which 61.05 square miles (158.1 km2) is land and 7.29 square miles (18.9 km2) (10.67%) is water. The District is bordered by Montgomery County, Maryland to the northwest; Prince George's County, Maryland to the east; Arlington County, Virginia to the south; and Alexandria, Virginia to the west.
The south bank of the Potomac River forms the District's border with Virginia and has two major tributaries: the Anacostia River and Rock Creek. Tiber Creek, a natural watercourse that once passed through the National Mall, was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and was used during the 19th century to bypass the Little Falls of the Potomac River, located at the northwest edge of Washington at the Atlantic Seaboard fall line.The highest natural elevation in the District is 409 feet (125 m) above sea level at Fort Reno Park in upper northwest Washington. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L Streets NW.The District has 7,464 acres (30.21 km2) of parkland, about 19% of the city's total area and the second-highest percentage among high-density U.S. cities. This factor contributed to Washington, D.C., being ranked as third in the nation for park access and quality in the 2018 ParkScore ranking of the park systems of the 100 most populous cities in the United States, according to the nonprofit Trust for Public Land.The National Park Service manages most of the 9,122 acres (36.92 km2) of city land owned by the U.S. government. Rock Creek Park is a 1,754-acre (7.10 km2) urban forest in Northwest Washington, which extends 9.3 miles (15.0 km) through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes. Other National Park Service properties include the C&O Canal National Historical Park, the National Mall and Memorial Parks, Theodore Roosevelt Island, Columbia Island, Fort Dupont Park, Meridian Hill Park, Kenilworth Park and Aquatic Gardens, and Anacostia Park. The D.C. Department of Parks and Recreation maintains the city's 900 acres (3.6 km2) of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers. The U.S. Department of Agriculture operates the 446-acre (1.80 km2) U.S. National Arboretum in Northeast Washington.
