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.
One example is below.
Q: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
A: Who believes Fagin's gang make wallets and handkerchiefs?.
Rationale: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: There have been railways in Portland since the early 19th century. The Merchant's Railway was the earliestit opened in 1826 (one year after the Stockton and Darlington railway) and ran from the quarries at the north of Tophill to a pier at Castletown, from where the Portland stone was shipped around the country. The Weymouth and Portland Railway was laid in 1865, and ran from a station in Melcombe Regis, across the Fleet and along the low isthmus behind Chesil Beach to a station at Victoria Square in Chiswell. At the end of the 19th century the line was extended to the top of the island as the Easton and Church Ope Railway, running through Castletown and ascending the cliffs at East Weares, to loop back north to a station in Easton. The line closed to passengers in 1952, and the final goods train (and two passenger 'specials') ran in April 1965.The Royal National Institution for the Preservation of Life from Shipwreck stationed a lifeboat at Portland in 1826, which was withdrawn in 1851. Coastal flooding has affected Portland's residents and transport for centuriesthe only way off the island by land is along the causeway in the lee of Chesil Beach. At times of extreme floods (about every 10 years) this road link is cut by floods. The low-lying village of Chiswell used to flood on average every 5 years. Chesil Beach occasionally faces severe storms and massive waves, which have a fetch across the Atlantic Ocean. Following two severe flood events in the 1970s, Weymouth and Portland Borough Council and Wessex Water decided to investigate the structure of the beach, and coastal management schemes that could be built to protect Chiswell and the beach road. In the 1980s it was agreed that a scheme to protect against a one-in-five-year storm would be practicable; it would reduce flood depth and duration in more severe storms. Hard engineering techniques were employed in the scheme, including a gabion running 550 metres (600 yd) to the north of Chiswell, an extended sea wall in Chesil Cove, and a culvert running from inside the beach, underneath the beach road and into Portland Harbour, to divert flood water away from low-lying areas.
A:
Where was an extended sea wall built in the city where coastal flooding has affected residents for centuries?
