Given the task definition, example input & output, solve the new input case.
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.
Example: 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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input case for you: Passage: Efforts began shortly after the explosion to clear debris, repair buildings, and establish temporary housing for survivors left homeless by the explosion. By late January 1918, around 5,000 were still without shelter. A reconstruction committee under Colonel Robert Low constructed 832 new housing units, which were furnished by the Massachusetts-Halifax Relief Fund.Partial train service resumed from a temporary rail terminal in the city's South End on 7 December. Full service resumed on 9 December when tracks were cleared and the North Street Station reopened. The Canadian Government Railways created a special unit to clear and repair railway yards as well as rebuild railway piers and the Naval Dockyard. Most piers returned to operation by late December and were repaired by January.
The North End Halifax neighbourhood of Richmond bore the brunt of the explosion. In 1917, Richmond was considered a working-class neighbourhood and had few paved roads. After the explosion, the Halifax Relief Commission approached the reconstruction of Richmond as an opportunity to improve and modernize the city's North End. English town planner Thomas Adams and Montreal architectural firm Ross and Macdonald were recruited to design a new housing plan for Richmond. Adams, inspired by the Victorian garden city movement, aimed to provide public access to green spaces and to create a low-rise, low-density and multifunctional urban neighbourhood. The planners designed 326 large homes that each faced a tree-lined, paved boulevard. They specified that the homes be built with a new and innovative fireproof material, blocks of compressed cement called Hydrostone. The first of these homes was occupied by March 1919. Once finished, the Hydrostone neighbourhood consisted of homes, businesses and parks, which helped create a new sense of community in the North End of Halifax. It has now become an upscale neighbourhood and shopping district. In contrast, the equally poor and underdeveloped area of Africville was not included in reconstruction efforts.Every building in the Halifax dockyard required some degree of rebuilding, as did HMCS Niobe and the docks themselves; all of the Royal Canadian Navy's minesweepers and patrol boats were undamaged. Prime Minister Robert Borden pledged that the government would be "co-operating in every way to reconstruct the Port of Halifax: this was of utmost importance to the Empire". Captain Symington of USS Tacoma speculated that the port would not be operational for months, but a convoy departed on 11 December and dockyard operations resumed before Christmas.
Output:
What is the name of the neighborhood that is now upscale and a shopping district?
