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: Bristol, the largest city in South West England, has an eclectic combination of architectural styles, ranging from the medieval to 20th century brutalism and beyond. During the mid-19th century, Bristol Byzantine, an architectural style unique to the city, was developed, and several examples have survived.
Buildings from most of the architectural periods of the United Kingdom can be seen throughout Bristol. Parts of the fortified city and castle date back to the medieval era, as do some churches dating from the 12th century onwards. Outside the historical city centre there are several large Tudor mansions built for wealthy merchants. Almshouses and public houses of the same period survive, intermingled with areas of more recent development. Several Georgian-era squares were laid out for the enjoyment of the middle class. As the city grew, it merged with its surrounding villages, each with its own character and centre, often clustered around a parish church.
The construction of the city's Floating Harbour, taking in the wharves on the River Avon and Frome, provided a focus for industrial development and the growth of the local transport infrastructure. Key elements of which include the Isambard Kingdom Brunel designed Clifton Suspension Bridge and Temple Meads terminus; the latter served from 2002 to 2009 as the British Empire and Commonwealth Museum, but is now closed.The 20th century saw further expansion of the city, the growth of the University of Bristol and the arrival of the aircraft industry. During World War II, the city centre was extensively bombed in the Bristol Blitz. The redevelopment of shopping centres, office buildings, and the harbourside continues to this day.
