Problem: Israel:

Israeli music contains musical influences from all over the world; Sephardic music, Hasidic melodies, Belly dancing music, Greek music, jazz, and pop rock are all part of the music scene. Among Israel's world-renowned orchestras is the Israel Philharmonic Orchestra, which has been in operation for over seventy years and today performs more than two hundred concerts each year. Israel has also produced many musicians of note, some achieving international stardom. Itzhak Perlman, Pinchas Zukerman and Ofra Haza are among the internationally acclaimed musicians born in Israel.[citation needed] Israel has participated in the Eurovision Song Contest nearly every year since 1973, winning the competition three times and hosting it twice. Eilat has hosted its own international music festival, the Red Sea Jazz Festival, every summer since 1987.

Problem: Sextus Julius Africanus further refers to the writings of historian Thallus: "This darkness Thallus, in the third book of his History, calls, as appears to me without reason, an eclipse of the sun. For the Hebrews celebrate the passover on the 14th day according to the moon, and the passion of our Saviour falls on the day before the passover; but an eclipse of the sun takes place only when the moon comes under the sun." Christian apologist Tertullian believed the event was documented in the Roman archives.
For how many years had the Romans kept archives?

The simplest known circadian clock is that of the prokaryotic cyanobacteria. Recent research has demonstrated that the circadian clock of Synechococcus elongatus can be reconstituted in vitro with just the three proteins (KaiA, KaiB, KaiC) of their central oscillator. This clock has been shown to sustain a 22-hour rhythm over several days upon the addition of ATP. Previous explanations of the prokaryotic circadian timekeeper were dependent upon a DNA transcription/translation feedback mechanism.[citation needed]
What was the minimum amount of time the clock could be sustained in vitro?
A: unanswerable


Context and question: Varmint hunting is an American phrase for the selective killing of non-game animals seen as pests. While not always an efficient form of pest control, varmint hunting achieves selective control of pests while providing recreation and is much less regulated. Varmint species are often responsible for detrimental effects on crops, livestock, landscaping, infrastructure, and pets. Some animals, such as wild rabbits or squirrels, may be utilised for fur or meat, but often no use is made of the carcass. Which species are varmints depends on the circumstance and area. Common varmints may include various rodents, coyotes, crows, foxes, feral cats, and feral hogs. Some animals once considered varmints are now protected, such as wolves. In the US state of Louisiana, a non-native rodent known as a nutria has become so destructive to the local ecosystem that the state has initiated a bounty program to help control the population.
What does having livestock cause detrimental effects on when you own a farm?
Answer: unanswerable


Question: As musicians depended more and more on public support, public concerts became increasingly popular and helped supplement performers' and composers' incomes. The concerts also helped them to reach a wider audience. Handel, for example, epitomized this with his highly public musical activities in London. He gained considerable fame there with performances of his operas and oratorios. The music of Haydn and Mozart, with their Viennese Classical styles, are usually regarded as being the most in line with the Enlightenment ideals.
Is there an answer to this question: Whose incomes did public concerts help support?

Answer: performers' and composers'

NigeriaSat-2, Nigeria's second satellite, was built as a high-resolution earth satellite by Surrey Space Technology Limited, a United Kingdom-based satellite technology company. It has 2.5-metre resolution panchromatic (very high resolution), 5-metre multispectral (high resolution, NIR red, green and red bands), and 32-metre multispectral (medium resolution, NIR red, green and red bands) antennas, with a ground receiving station in Abuja. The NigeriaSat-2 spacecraft alone was built at a cost of over £35 million. This satellite was launched into orbit from a military base in China.
Where was Nigeria's second satellite manufactured?
A:
United Kingdom
