Input: Read this: A few centuries later, coinciding with the first waves of the invading Germanic peoples (Suevi, Vandals and Alans, and later the Visigoths) and the power vacuum left by the demise of the Roman imperial administration, the church assumed the reins of power in the city and replaced the old Roman temples with religious buildings. With the Byzantine invasion of the southwestern Iberian peninsula in 554 the city acquired strategic importance. After the expulsion of the Byzantines in 625, Visigothic military contingents were posted there and the ancient Roman amphitheatre was fortified. Little is known of its history for nearly a hundred years; although this period is only scarcely documented by archeology, excavations suggest that there was little development of the city. During Visigothic times Valencia was an episcopal See of the Catholic Church, albeit a suffragan diocese subordinate to the archdiocese of Toledo, comprising the ancient Roman province of Carthaginensis in Hispania.
Question: Who took power in Valencia after the Roman administration was gone?

Output: the church

QUES: Douglas's business grew astronomically with the onset of World War II, employing as many as 44,000 people in 1943. To defend against air attack set designers from the Warner Brothers Studios prepared elaborate camouflage that disguised the factory and airfield. The RAND Corporation began as a project of the Douglas Company in 1945, and spun off into an independent think tank on May 14, 1948. RAND eventually acquired a 15-acre (61,000 m) campus centrally located between the Civic Center and the pier entrance.

What was the camouflage designed to do?
What is the answer?
ANS: defend against air attack

QUES: He turned to medicine at 16, and not only learned medical theory, but also by gratuitous attendance of the sick had, according to his own account, discovered new methods of treatment. The teenager achieved full status as a qualified physician at age 18, and found that "Medicine is no hard and thorny science, like mathematics and metaphysics, so I soon made great progress; I became an excellent doctor and began to treat patients, using approved remedies." The youthful physician's fame spread quickly, and he treated many patients without asking for payment.
What subject did Avicenna stop studying at 16?

ANS: unanswerable

The convention in the English language is to call nearly all national heads of government "prime minister" (sometimes modified to the equivalent term of premier), regardless of the correct title of the head of government as applied in his or her respective country. The few exceptions to the rule are Germany and Austria, whose heads of government titles are almost always translated as Chancellor; Monaco, whose head of government is referred to as the Minister of State; and Vatican City, for which the head of government is titled the Secretary of State. In the case of Ireland, the head of government is occasionally referred to as the Taoiseach by English speakers. A stand-out case is the President of Iran, who is not actually a head of state, but the head of the government of Iran. He is referred to as "president" in both the Persian and English languages.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a term that is used to mean prime minister?
Ah, so.. premier

Question: Because of the distance of Neptune from Earth, its angular diameter only ranges from 2.2 to 2.4 arcseconds, the smallest of the Solar System planets. Its small apparent size makes it challenging to study it visually. Most telescopic data was fairly limited until the advent of Hubble Space Telescope (HST) and large ground-based telescopes with adaptive optics (AO). The first scientifically useful observation of Neptune from ground-based telescopes using adaptive optics, was commenced in 1997 from Hawaii. Neptune is currently entering its spring and summer season and has been shown to be heating up, with increased atmospheric activity and brightness as a consequence. Combined with technological advancements, ground-based telescopes with adaptive optics are recording increasingly more detailed images of this Outer Planet. Both the HST and AO telescopes on Earth has made many new discoveries within the Solar System since the mid-1990s, with a large increase in the number of known satellites and moons around the Outer Planets for example. In 2004 and 2005, five new small satellites of Neptune with diameters between 38 and 61 kilometres were discovered.
Try to answer this question if possible: What is Neptune's angular diameter range?
Answer: 2.2 to 2.4 arcseconds

QUES: Although most hardware clones were not produced under license by Nintendo, certain companies were granted licenses to produce NES-compatible devices. The Sharp Corporation produced at least two such clones: the Twin Famicom and the SHARP 19SC111 television. The Twin Famicom was compatible with both Famicom cartridges and Famicom Disk System disks. It was available in two colors (red and black) and used hardwired controllers (as did the original Famicom), but it featured a different case design. The SHARP 19SC111 television was a television which included a built-in Famicom. A similar licensing deal was reached with Hyundai Electronics, who licensed the system under the name Comboy in the South Korean market. This deal with Hyundai was made necessary because of the South Korean government's wide ban on all Japanese "cultural products", which remained in effect until 1998 and ensured that the only way Japanese products could legally enter the South Korean market was through licensing to a third-party (non-Japanese) distributor (see also JapanKorea disputes).
How could Japanese products only enter South Korea?

ANS:
licensing to a third-party (non-Japanese) distributor
