Input: Read this: There are three primary shopping centers in the Bronx: The Hub, Gateway Center and Southern Boulevard. The Hub–Third Avenue Business Improvement District (B.I.D.), in The Hub, is the retail heart of the South Bronx, located where four roads converge: East 149th Street, Willis, Melrose and Third Avenues. It is primarily located inside the neighborhood of Melrose but also lines the northern border of Mott Haven. The Hub has been called "the Broadway of the Bronx", being likened to the real Broadway in Manhattan and the northwestern Bronx. It is the site of both maximum traffic and architectural density. In configuration, it resembles a miniature Times Square, a spatial "bow-tie" created by the geometry of the street. The Hub is part of Bronx Community Board 1.
Question: What is The Hub's nickname?

Output: "the Broadway of the Bronx"


QUES: All major cities have their distinctive local department stores, which anchored the downtown shopping district until the arrival of the malls in the 1960s. Washington, for example, after 1887 had Woodward & Lothrop and Garfinckel's starting in 1905. Garfield's went bankrupt in 1990, as did Woodward & Lothrop in 1994. Baltimore had four major department stores: Hutzler's was the prestige leader, followed by Hecht's, Hochschild's and Stewart's. They all operated branches in the suburbs, but all closed in the late twentieth century. By 2015, most locally owned department stores around the country had been consolidated into larger chains, or had closed down entirely.

When did Garfinckel's end operating in Washington? 
What is the answer?

QUES: A revolution in 1332 resulted in a broad-based city government with participation of the guilds, and Strasbourg declared itself a free republic. The deadly bubonic plague of 1348 was followed on 14 February 1349 by one of the first and worst pogroms in pre-modern history: over a thousand Jews were publicly burnt to death, with the remainder of the Jewish population being expelled from the city. Until the end of the 18th century, Jews were forbidden to remain in town after 10 pm. The time to leave the city was signalled by a municipal herald blowing the Grüselhorn (see below, Museums, Musée historique);. A special tax, the Pflastergeld (pavement money), was furthermore to be paid for any horse that a Jew would ride or bring into the city while allowed to.
What did the Jews need to pay to ride a horse into town?

ANS: special tax


It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do annelids' larvae live like?
Ah, so.. plankton


Question: Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.
Try to answer this question if possible: When the PCB is stripped, what is finished?
Answer: unanswerable


QUES: Krugman's contention (that the growth of a commercial real estate bubble indicates that U.S. housing policy was not the cause of the crisis) is challenged by additional analysis. After researching the default of commercial loans during the financial crisis, Xudong An and Anthony B. Sanders reported (in December 2010): "We find limited evidence that substantial deterioration in CMBS [commercial mortgage-backed securities] loan underwriting occurred prior to the crisis." Other analysts support the contention that the crisis in commercial real estate and related lending took place after the crisis in residential real estate. Business journalist Kimberly Amadeo reports: "The first signs of decline in residential real estate occurred in 2006. Three years later, commercial real estate started feeling the effects. Denice A. Gierach, a real estate attorney and CPA, wrote:
According to business journalist Kimberly Amadeo, when did the first signs of decline in real estate occur?
