Problem: The Bronx:

East of the Bronx River, the borough is relatively flat and includes four large low peninsulas, or 'necks,' of low-lying land which jut into the waters of the East River and were once saltmarsh: Hunts Point, Clason's Point, Screvin's Neck (Castle Hill Point) and Throgs Neck. The East Bronx has older tenement buildings, low income public housing complexes, and multifamily homes, as well as single family homes. It includes New York City's largest park: Pelham Bay Park along the Westchester-Bronx border.

What is NYC's largest park?
---
A: Pelham Bay Park


Problem: Starting at the transition between the Middle to Upper Paleolithic period, some 80,000 to 70,000 years ago, some hunter-gatherers bands began to specialize, concentrating on hunting a smaller selection of (often larger) game and gathering a smaller selection of food. This specialization of work also involved creating specialized tools, like fishing nets and hooks and bone harpoons. The transition into the subsequent Neolithic period is chiefly defined by the unprecedented development of nascent agricultural practices. Agriculture originated and spread in several different areas including the Middle East, Asia, Mesoamerica, and the Andes beginning as early as 12,000 years ago.
When hunter-gatherers began to specialize, they concentrated on a larger selection of what?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Ashkenazi Jews represent the bulk of modern Jewry, with at least 70% of Jews worldwide (and up to 90% prior to World War II and the Holocaust). As a result of their emigration from Europe, Ashkenazim also represent the overwhelming majority of Jews in the New World continents, in countries such as the United States, Canada, Argentina, Australia, and Brazil. In France, the immigration of Jews from Algeria (Sephardim) has led them to outnumber the Ashkenazim. Only in Israel is the Jewish population representative of all groups, a melting pot independent of each group's proportion within the overall world Jewish population.
Which group represents less than 70% of Jews worldwide?
A: unanswerable


Context and question: Other public festivals were not required by the calendar, but occasioned by events. The triumph of a Roman general was celebrated as the fulfillment of religious vows, though these tended to be overshadowed by the political and social significance of the event. During the late Republic, the political elite competed to outdo each other in public display, and the ludi attendant on a triumph were expanded to include gladiator contests. Under the Principate, all such spectacular displays came under Imperial control: the most lavish were subsidised by emperors, and lesser events were provided by magistrates as a sacred duty and privilege of office. Additional festivals and games celebrated Imperial accessions and anniversaries. Others, such as the traditional Republican Secular Games to mark a new era (saeculum), became imperially funded to maintain traditional values and a common Roman identity. That the spectacles retained something of their sacral aura even in late antiquity is indicated by the admonitions of the Church Fathers that Christians should not take part.
In what aspect of the festival did political figures try to out do each other?
Answer: public display

Problem: Asphalt:

Synthetic crude oil, also known as syncrude, is the output from a bitumen upgrader facility used in connection with oil sand production in Canada. Bituminous sands are mined using enormous (100 ton capacity) power shovels and loaded into even larger (400 ton capacity) dump trucks for movement to an upgrading facility. The process used to extract the bitumen from the sand is a hot water process originally developed by Dr. Karl Clark of the University of Alberta during the 1920s. After extraction from the sand, the bitumen is fed into a bitumen upgrader which converts it into a light crude oil equivalent. This synthetic substance is fluid enough to be transferred through conventional oil pipelines and can be fed into conventional oil refineries without any further treatment. By 2015 Canadian bitumen upgraders were producing over 1 million barrels (160×10^3 m3) per day of synthetic crude oil, of which 75% was exported to oil refineries in the United States.

Where is the mined bitumen taken for refining?
---
A:
upgrading facility
