Problem: States of Germany:

The governments in Berlin, Bremen and Hamburg are designated by the term Senate. In the three free states of Bavaria, Saxony, and Thuringia the government is referred to as the State Government (Staatsregierung), and in the other ten states the term Land Government (Landesregierung) is used. Before January 1, 2000, Bavaria had a bicameral parliament, with a popularly elected Landtag, and a Senate made up of representatives of the state's major social and economic groups. The Senate was abolished following a referendum in 1998. The states of Berlin, Bremen, and Hamburg are governed slightly differently from the other states. In each of those cities, the executive branch consists of a Senate of approximately eight, selected by the state's parliament; the senators carry out duties equivalent to those of the ministers in the larger states. The equivalent of the Minister-President is the Senatsprasident (President of the Senate) in Bremen, the Erster Burgermeister (First Mayor) in Hamburg, and the Regierender Burgermeister (Governing Mayor) in Berlin. The parliament for Berlin is called the Abgeordnetenhaus (House of Representatives), while Bremen and Hamburg both have a Burgerschaft. The parliaments in the remaining 13 states are referred to as Landtag (State Parliament).

The parliament in Berlin is called what?
---
A: Abgeordnetenhaus

Problem: Computers control functions at many utilities, including coordination of telecommunications, the power grid, nuclear power plants, and valve opening and closing in water and gas networks. The Internet is a potential attack vector for such machines if connected, but the Stuxnet worm demonstrated that even equipment controlled by computers not connected to the Internet can be vulnerable to physical damage caused by malicious commands sent to industrial equipment (in that case uranium enrichment centrifuges) which are infected via removable media. In 2014, the Computer Emergency Readiness Team, a division of the Department of Homeland Security, investigated 79 hacking incidents at energy companies.
When was the Stuxnet worm created?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Humans regard certain insects as pests, and attempt to control them using insecticides and a host of other techniques. Some insects damage crops by feeding on sap, leaves or fruits. A few parasitic species are pathogenic. Some insects perform complex ecological roles; blow-flies, for example, help consume carrion but also spread diseases. Insect pollinators are essential to the life-cycle of many flowering plant species on which most organisms, including humans, are at least partly dependent; without them, the terrestrial portion of the biosphere (including humans) would be devastated. Many other insects are considered ecologically beneficial as predators and a few provide direct economic benefit. Silkworms and bees have been used extensively by humans for the production of silk and honey, respectively. In some cultures, people eat the larvae or adults of certain insects.
Humans consider most insects as what?
A: pests

Context and question: According to the New Jersey Press Association, several media entities refrain from using the term "ultra-Orthodox", including the Religion Newswriters Association; JTA, the global Jewish news service; and the Star-Ledger, New Jersey's largest daily newspaper. The Star-Ledger was the first mainstream newspaper to drop the term. Several local Jewish papers, including New York's Jewish Week and Philadelphia's Jewish Exponent have also dropped use of the term. According to Rabbi Shammai Engelmayer, spiritual leader of Temple Israel Community Center in Cliffside Park and former executive editor of Jewish Week, this leaves "Orthodox" as "an umbrella term that designates a very widely disparate group of people very loosely tied together by some core beliefs."
What is the global Jewish news service known as?
Answer: JTA

Question: Despite Laemmle's role as an innovator, he was an extremely cautious studio chief. Unlike rivals Adolph Zukor, William Fox, and Marcus Loew, Laemmle chose not to develop a theater chain. He also financed all of his own films, refusing to take on debt. This policy nearly bankrupted the studio when actor-director Erich von Stroheim insisted on excessively lavish production values for his films Blind Husbands (1919) and Foolish Wives (1922), but Universal shrewdly gained a return on some of the expenditure by launching a sensational ad campaign that attracted moviegoers. Character actor Lon Chaney became a drawing card for Universal in the 1920s, appearing steadily in dramas. His two biggest hits for Universal were The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925). During this period Laemmle entrusted most of the production policy decisions to Irving Thalberg. Thalberg had been Laemmle's personal secretary, and Laemmle was impressed by his cogent observations of how efficiently the studio could be operated. Promoted to studio chief, Thalberg was giving Universal's product a touch of class, but MGM's head of production Louis B. Mayer lured Thalberg away from Universal with a promise of better pay. Without his guidance Universal became a second-tier studio, and would remain so for several decades.
Is there an answer to this question: What year did Blind Wives come out?

Answer: unanswerable

QUES: Purely electronic circuit elements soon replaced their mechanical and electromechanical equivalents, at the same time that digital calculation replaced analog. The engineer Tommy Flowers, working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange. Experimental equipment that he built in 1934 went into operation 5 years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes. In the US, John Vincent Atanasoff and Clifford E. Berry of Iowa State University developed and tested the AtanasoffBerry Computer (ABC) in 1942, the first "automatic electronic digital computer". This design was also all-electronic and used about 300 vacuum tubes, with capacitors fixed in a mechanically rotating drum for memory.

How many vacuum tubes did the Atanasoff-Berry computer use?
What is the answer?
ANS:
about 300
