Problem: USB:

In July 2012, the USB Promoters Group announced the finalization of the USB Power Delivery ("PD") specification, an extension that specifies using certified "PD aware" USB cables with standard USB Type-A and Type-B connectors to deliver increased power (more than 7.5 W) to devices with larger power demand. Devices can request higher currents and supply voltages from compliant hosts up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W or 60 W) or 20 V (60 W or 100 W). In all cases, both host-to-device and device-to-host configurations are supported.

Problem: In 1919, following the Treaty of Versailles, the city was restituted to France in accordance with U.S. President Woodrow Wilson's "Fourteen Points" without a referendum. The date of the assignment was retroactively established on Armistice Day. It is doubtful whether a referendum in Strasbourg would have ended in France's favour since the political parties striving for an autonomous Alsace or a connection to France accounted only for a small proportion of votes in the last Reichstag as well as in the local elections. The Alsatian autonomists who were pro French had won many votes in the more rural parts of the region and other towns since the annexation of the region by Germany in 1871. The movement started with the first election for the Reichstag; those elected were called "les deputes protestataires", and until the fall of Bismarck in 1890, they were the only deputies elected by the Alsatians to the German parliament demanding the return of those territories to France. At the last Reichstag election in Strasbourg and its periphery, the clear winners were the Social Democrats; the city was the administrative capital of the region, was inhabited by many Germans appointed by the central government in Berlin and its flourishing economy attracted many Germans. This could explain the difference between the rural vote and the one in Strasbourg. After the war, many Germans left Strasbourg and went back to Germany; some of them were denounced by the locals or expelled by the newly appointed authorities. The Saverne Affair was vivid in the memory among the Alsatians.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In Whitehead's view, then, concepts such as "quality", "matter", and "form" are problematic. These "classical" concepts fail to adequately account for change, and overlook the active and experiential nature of the most basic elements of the world. They are useful abstractions, but are not the world's basic building blocks. What is ordinarily conceived of as a single person, for instance, is philosophically described as a continuum of overlapping events. After all, people change all the time, if only because they have aged by another second and had some further experience. These occasions of experience are logically distinct, but are progressively connected in what Whitehead calls a "society" of events. By assuming that enduring objects are the most real and fundamental things in the universe, materialists have mistaken the abstract for the concrete (what Whitehead calls the "fallacy of misplaced concreteness").
What basic concepts did Whitehead believe were questionable?
A: "quality", "matter", and "form"

Context and question: The first step, where the wort is prepared by mixing the starch source (normally malted barley) with hot water, is known as "mashing". Hot water (known as "liquor" in brewing terms) is mixed with crushed malt or malts (known as "grist") in a mash tun. The mashing process takes around 1 to 2 hours, during which the starches are converted to sugars, and then the sweet wort is drained off the grains. The grains are now washed in a process known as "sparging". This washing allows the brewer to gather as much of the fermentable liquid from the grains as possible. The process of filtering the spent grain from the wort and sparge water is called wort separation. The traditional process for wort separation is lautering, in which the grain bed itself serves as the filter medium. Some modern breweries prefer the use of filter frames which allow a more finely ground grist.
What is the first step of brewing when malted barley is mixed with hot water?
Answer: mashing

Question: During the latter half of the 20th century, Washington University transitioned from a strong regional university to a national research institution. In 1957, planning began for the construction of the "South 40," a complex of modern residential halls. With the additional on-campus housing, Washington University, which had been predominantly a "streetcar college" of commuter students, began to attract a more national pool of applicants. By 1964, over two-thirds of incoming students came from outside the St. Louis area.
Is there an answer to this question: What proportion of students at Washington University came from outside the St. Louis area by 1964?

Answer: over two-thirds

Vladimir's choice of Eastern Christianity may also have reflected his close personal ties with Constantinople, which dominated the Black Sea and hence trade on Kiev's most vital commercial route, the Dnieper River. Adherence to the Eastern Church had long-range political, cultural, and religious consequences. The church had a liturgy written in Cyrillic and a corpus of translations from Greek that had been produced for the Slavic peoples. This literature facilitated the conversion to Christianity of the Eastern Slavs and introduced them to rudimentary Greek philosophy, science, and historiography without the necessity of learning Greek (there were some merchants who did business with Greeks and likely had an understanding of contemporary business Greek). In contrast, educated people in medieval Western and Central Europe learned Latin. Enjoying independence from the Roman authority and free from tenets of Latin learning, the East Slavs developed their own literature and fine arts, quite distinct from those of other Eastern Orthodox countries.[citation needed] (See Old East Slavic language and Architecture of Kievan Rus for details ). Following the Great Schism of 1054, the Rus' church maintained communion with both Rome and Constantinople for some time, but along with most of the Eastern churches it eventually split to follow the Eastern Orthodox. That being said, unlike other parts of the Greek world, Kievan Rus' did not have a strong hostility to the Western world.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the West Slavs develop?
Ah, so..
unanswerable
