Problem: Madrasa:

In Singapore, madrasahs are private schools which are overseen by Majlis Ugama Islam Singapura (MUIS, English: Islamic Religious Council of Singapore). There are six Madrasahs in Singapore, catering to students from Primary 1 to Secondary 4. Four Madrasahs are coeducational and two are for girls. Students take a range of Islamic Studies subjects in addition to mainstream MOE curriculum subjects and sit for the PSLE and GCE 'O' Levels like their peers. In 2009, MUIS introduced the "Joint Madrasah System" (JMS), a joint collaboration of Madrasah Al-Irsyad Al-Islamiah primary school and secondary schools Madrasah Aljunied Al-Islamiah (offering the ukhrawi, or religious stream) and Madrasah Al-Arabiah Al-Islamiah (offering the academic stream). The JMS aims to introduce the International Baccalaureate (IB) programme into the Madrasah Al-Arabiah Al-Islamiah by 2019. Students attending a madrasah are required to wear the traditional Malay attire, including the songkok for boys and tudong for girls, in contrast to mainstream government schools which ban religious headgear as Singapore is officially a secular state. For students who wish to attend a mainstream school, they may opt to take classes on weekends at the madrasah instead of enrolling full-time.

A: six


Problem: Known during development as Xbox Next, Xenon, Xbox 2, Xbox FS or NextBox, the Xbox 360 was conceived in early 2003. In February 2003, planning for the Xenon software platform began, and was headed by Microsoft's Vice President J Allard. That month, Microsoft held an event for 400 developers in Bellevue, Washington to recruit support for the system. Also that month, Peter Moore, former president of Sega of America, joined Microsoft. On August 12, 2003, ATI signed on to produce the graphic processing unit for the new console, a deal which was publicly announced two days later. Before the launch of the Xbox 360, several Alpha development kits were spotted using Apple's Power Mac G5 hardware. This was because the system's PowerPC 970 processor running the same PowerPC architecture that the Xbox 360 would eventually run under IBM's Xenon processor. The cores of the Xenon processor were developed using a slightly modified version of the PlayStation 3's Cell Processor PPE architecture. According to David Shippy and Mickie Phipps, the IBM employees were "hiding" their work from Sony and Toshiba, IBM's partners in developing the Cell Processor. Jeff Minter created the music visualization program Neon which is included with the Xbox 360.
Who replaced Peter Moore as the president of Sega?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Around 10,200 BC the first fully developed Neolithic cultures belonging to the phase Pre-Pottery Neolithic A (PPNA) appeared in the fertile crescent. Around 10,700 to 9,400 BC a settlement was established in Tell Qaramel, 10 miles north of Aleppo. The settlement included 2 temples dating back to 9,650. Around 9000 BC during the PPNA, one of the world's first towns, Jericho, appeared in the Levant. It was surrounded by a stone and marble wall and contained a population of 2000–3000 people and a massive stone tower. Around 6,400 BC the Halaf culture appeared in Lebanon, Israel and Palestine, Syria, Anatolia, and Northern Mesopotamia and subsisted on dryland agriculture.
What materials were used to build the wall around Jericho?
A: stone and marble


Context and question: Matte solder is usually fused to provide a better bonding surface or stripped to bare copper. Treatments, such as benzimidazolethiol, prevent surface oxidation of bare copper. The places to which components will be mounted are typically plated, because untreated bare copper oxidizes quickly, and therefore is not readily solderable. Traditionally, any exposed copper was coated with solder by hot air solder levelling (HASL). The HASL finish prevents oxidation from the underlying copper, thereby guaranteeing a solderable surface. This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead. One of these lead-free compounds is SN100CL, made up of 99.3% tin, 0.7% copper, 0.05% nickel, and a nominal of 60ppm germanium.
What's the process by which bare copper gets covered in solder?
Answer: hot air solder levelling


Question: A TiVo service update in July 2008 allowed the system to search and play YouTube videos. In January 2009, YouTube launched "YouTube for TV", a version of the website tailored for set-top boxes and other TV-based media devices with web browsers, initially allowing its videos to be viewed on the PlayStation 3 and Wii video game consoles. In June 2009, YouTube XL was introduced, which has a simplified interface designed for viewing on a standard television screen. YouTube is also available as an app on Xbox Live. On November 15, 2012, Google launched an official app for the Wii, allowing users to watch YouTube videos from the Wii channel. An app is also available for Wii U and Nintendo 3DS, and videos can be viewed on the Wii U Internet Browser using HTML5. Google made YouTube available on the Roku player on December 17, 2013 and in October 2014, the Sony PlayStation 4.
Is there an answer to this question: What was introduced in June 2008?

Answer: unanswerable


Question: Burke believed that property was essential to human life. Because of his conviction that people desire to be ruled and controlled, the division of property formed the basis for social structure, helping develop control within a property-based hierarchy. He viewed the social changes brought on by property as the natural order of events, which should be taking place as the human race progressed. With the division of property and the class system, he also believed that it kept the monarch in check to the needs of the classes beneath the monarch. Since property largely aligned or defined divisions of social class, class too, was seen as natural—part of a social agreement that the setting of persons into different classes, is the mutual benefit of all subjects. Concern for property is not Burke's only influence. As Christopher Hitchens summarises, "If modern conservatism can be held to derive from Burke, it is not just because he appealed to property owners in behalf of stability but also because he appealed to an everyday interest in the preservation of the ancestral and the immemorial."
Is there an answer to this question: What did Burke think a social hierarchy should be based on?

Answer:
property
