Problem: Israel:

Israel has a school life expectancy of 15.5 years and a literacy rate of 97.1% according to the United Nations. The State Education Law, passed in 1953, established five types of schools: state secular, state religious, ultra orthodox, communal settlement schools, and Arab schools. The public secular is the largest school group, and is attended by the majority of Jewish and non-Arab pupils in Israel. Most Arabs send their children to schools where Arabic is the language of instruction. Education is compulsory in Israel for children between the ages of three and eighteen. Schooling is divided into three tiers – primary school (grades 1–6), middle school (grades 7–9), and high school (grades 10–12) – culminating with Bagrut matriculation exams. Proficiency in core subjects such as mathematics, the Hebrew language, Hebrew and general literature, the English language, history, Biblical scripture and civics is necessary to receive a Bagrut certificate. In Arab, Christian and Druze schools, the exam on Biblical studies is replaced by an exam on Muslim, Christian or Druze heritage. Christian Arabs are one of the most educated groups in Israel. Maariv have describe the Christian Arabs sectors as "the most successful in education system", since Christian Arabs fared the best in terms of education in comparison to any other group receiving an education in Israel. Israeli children from Russian-speaking families have a higher bagrut pass rate at high-school level. Although amongst immigrant children born in the FSU, the bagrut pass rate is highest amongst those families from Western FSU states of Russia, Ukraine, Belarus and Moldova (at 62.6%), and lower amongst those from Central Asian and Caucasian FSU states. In 2003, over half of all Israeli twelfth graders earned a matriculation certificate.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. Uranium is the 51st element in order of abundance in the Earth's crust. Uranium is also the highest-numbered element to be found naturally in significant quantities on Earth and is almost always found combined with other elements. Along with all elements having atomic weights higher than that of iron, it is only naturally formed in supernovae. The decay of uranium, thorium, and potassium-40 in the Earth's mantle is thought to be the main source of heat that keeps the outer core liquid and drives mantle convection, which in turn drives plate tectonics.
In what state is the Earth's inner core?
A: unanswerable


Context and question: In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius's theological views appear to have been firmly rooted in Alexandrian Christianity, and his Christological views were certainly not radical at all. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Support for Arius from powerful bishops like Eusebius of Caesarea and Eusebius of Nicomedia, further illustrate how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position.
What made Arius's belief about Jesus the same from Alexander's?
Answer: unanswerable


Question: Armenian literature dates back to 400 AD, when Mesrop Mashtots first invented the Armenian alphabet. This period of time is often viewed as the Golden Age of Armenian literature. Early Armenian literature was written by the "father of Armenian history", Moses of Chorene, who authored The History of Armenia. The book covers the time-frame from the formation of the Armenian people to the fifth century AD. The nineteenth century beheld a great literary movement that was to give rise to modern Armenian literature. This period of time, during which Armenian culture flourished, is known as the Revival period (Zartonki sherchan). The Revivalist authors of Constantinople and Tiflis, almost identical to the Romanticists of Europe, were interested in encouraging Armenian nationalism. Most of them adopted the newly created Eastern or Western variants of the Armenian language depending on the targeted audience, and preferred them over classical Armenian (grabar). This period ended after the Hamidian massacres, when Armenians experienced turbulent times. As Armenian history of the 1920s and of the Genocide came to be more openly discussed, writers like Paruyr Sevak, Gevork Emin, Silva Kaputikyan and Hovhannes Shiraz began a new era of literature.
Is there an answer to this question: What work was written by Silva Kaputikyan?

Answer: unanswerable


Problem: Guam:

Before the introduction of the brown tree snake, Guam was home to several endemic bird species. Among them were the Guam rail (or ko'ko' bird in Chamorro) and the Guam flycatcher, both common throughout the island. Today the flycatcher is entirely extinct while the Guam rail is extinct in the wild but bred in captivity by the Division of Aquatic and Wildlife Resources. The devastation caused by the snake has been significant over the past several decades. As many as twelve bird species are believed to have been driven to extinction. According to many elders, ko'ko' birds were common in Guam before World War II.

What other bird was very common before WWII according to the elders?
---
A:
ko'ko' birds
