Problem: Please answer a question about the following article about East Prussia:
With the forced abdication of Emperor William II in 1918, Germany became a republic. Most of West Prussia and the former Prussian Province of Posen, territories annexed by Prussia in the 18th century Partitions of Poland, were ceded to the Second Polish Republic according to the Treaty of Versailles. East Prussia became an exclave, being separated from mainland Germany. After the Treaty of Versailles, East Prussia was separated from Germany as an exclave; the Memelland was also separated from the province. Because most of West Prussia became part of the Second Polish Republic as the Polish Corridor, the formerly West Prussian Marienwerder region became part of East Prussia (as Regierungsbezirk Westpreußen). Also Soldau district in Allenstein region was part of Second Polish Republic. The Seedienst Ostpreußen was established to provide an independent transport service to East Prussia.
In what year did Germany become a republic?
A: 1918

In 2010, a genetic study was conducted on the mummified remains of baboons that were brought back as gifts from Punt by the ancient Egyptians. Led by a research team from the Egyptian Museum and the University of California, the scientists used oxygen isotope analysis to examine hairs from two baboon mummies that had been preserved in the British Museum. One of the baboons had distorted isotopic data, so the other's oxygen isotope values were compared to those of present-day baboon specimens from regions of interest. The researchers found that the mummies most closely matched modern baboon specimens in Eritrea and Ethiopia, which they suggested implied that Punt was likely a narrow region that included eastern Ethiopia and all of Eritrea.

What type of analysis did the scientists use to examine hairs from the 2 baboon mummies formerly preserved in the British Museum?
Answer: oxygen isotope analysis


Problem: On 16 September 2001, at Camp David, President George W. Bush used the phrase war on terrorism in an unscripted and controversial comment when he said, "This crusade – this war on terrorism – is going to take a while, ... " Bush later apologized for this remark due to the negative connotations the term crusade has to people, e.g. of Muslim faith. The word crusade was not used again. On 20 September 2001, during a televised address to a joint session of congress, Bush stated that, "(o)ur 'war on terror' begins with al-Qaeda, but it does not end there. It will not end until every terrorist group of global reach has been found, stopped, and defeated."
When did George W. Bush first say 'war on terrorism'?
The answer is the following: 16 September 2001


At the beginning of the Western Han dynasty, thirteen centrally controlled commanderies—including the capital region—existed in the western third of the empire, while the eastern two-thirds were divided into ten semi-autonomous kingdoms. To placate his prominent commanders from the war with Chu, Emperor Gaozu enfeoffed some of them as kings. By 157 BC, the Han court had replaced all of these kings with royal Liu family members, since the loyalty of non-relatives to the throne was questioned. After several insurrections by Han kings—the largest being the Rebellion of the Seven States in 154 BC—the imperial court enacted a series of reforms beginning in 145 BC limiting the size and power of these kingdoms and dividing their former territories into new centrally controlled commanderies. Kings were no longer able to appoint their own staff; this duty was assumed by the imperial court. Kings became nominal heads of their fiefs and collected a portion of tax revenues as their personal incomes. The kingdoms were never entirely abolished and existed throughout the remainder of Western and Eastern Han.
How many commanderies were in the western third of the empire?
thirteen


Input: Child labour
Work is undertaken from an early age by vast numbers of children in the world and may have a natural place in growing up. Work can contribute to the well-being of children in a variety of ways; children often choose to work to improve their lives, both in the short- and long-term. At the material level, children’s work often contributes to producing food or earning income that benefits themselves and their families; and such income is especially important when the families are poor. Work can provide an escape from debilitating poverty, sometimes by allowing a young person to move away from an impoverished environment. Young people often enjoy their work, especially paid work, or when work involves the company of peers. Even when work is intensive and enforced, children often find ways to combine their work with play.

What are children able to do during intense work situations?
Output: children often find ways to combine their work with play


Problem: Please answer a question about the following article about MP3:
An MP3 file is made up of MP3 frames, which consist of a header and a data block. This sequence of frames is called an elementary stream. Due to the "byte reservoir", frames are not independent items and cannot usually be extracted on arbitrary frame boundaries. The MP3 Data blocks contain the (compressed) audio information in terms of frequencies and amplitudes. The diagram shows that the MP3 Header consists of a sync word, which is used to identify the beginning of a valid frame. This is followed by a bit indicating that this is the MPEG standard and two bits that indicate that layer 3 is used; hence MPEG-1 Audio Layer 3 or MP3. After this, the values will differ, depending on the MP3 file. ISO/IEC 11172-3 defines the range of values for each section of the header along with the specification of the header. Most MP3 files today contain ID3 metadata, which precedes or follows the MP3 frames, as noted in the diagram.
What is used to identify the begining of a valid frame of an MP3 header?
A:
