Detailed Instructions: 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.
Q: Passage: Half of MinneapolisSaint Paul residents work in the city where they live. Most residents drive cars, but 60% of the 160,000 people working downtown commute by means other than a single person per auto. The Metropolitan Council's Metro Transit, which operates the light rail system and most of the city's buses, provides free travel vouchers through the Guaranteed Ride Home program to allay fears that commuters might otherwise be occasionally stranded if, for example, they work late hours.On January 1, 2011, the city's limit of 343 taxis was lifted.Minneapolis currently has two light rail lines and one commuter rail line. The METRO Blue Line LRT (formerly the Hiawatha Line) serves 34,000 riders daily and connects the MinneapolisSaint Paul International Airport and Mall of America in Bloomington to downtown. Most of the line runs at surface level, although parts of the line run on elevated tracks (including the Franklin Avenue and Lake Street/Midtown stations) and approximately 2 miles (3.2 km) of the line runs underground, including the Lindbergh terminal subway station at the airport.
