Here is a question about this article: Although Kim's early successes had led him to predict that he would end the war by the end of August, Chinese leaders were more pessimistic. To counter a possible U.S. deployment, Zhou Enlai secured a Soviet commitment to have the Soviet Union support Chinese forces with air cover, and deployed 260,000 soldiers along the Korean border, under the command of Gao Gang. Zhou commanded Chai Chengwen to conduct a topographical survey of Korea, and directed Lei Yingfu, Zhou's military advisor in Korea, to analyze the military situation in Korea. Lei concluded that MacArthur would most likely attempt a landing at Incheon. After conferring with Mao that this would be MacArthur's most likely strategy, Zhou briefed Soviet and North Korean advisers of Lei's findings, and issued orders to Chinese army commanders deployed on the Korean border to prepare for American naval activity in the Korea Strait.
What is the answer to this question: Who helped North Korea prepare for war by surveying the country?
****
So... Chai Chengwen


The problem: Answer a question about this article:
There were several protests along the torch relay route. Members of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, including pro-democracy activist Szeto Wah, waved novelty inflatable plastic Olympic flames, which they said symbolised democracy. They wanted accountability for the Tiananmen Square protests of 1989 and the implementation of democracy in Hong Kong. Political activist and Legislative Council member Leung Kwok-hung (Longhair) also joined the protest, saying "I'm very proud that in Hong Kong we still have people brave enough to speak out." Pro-democracy activists were overwhelmed by a crowd of torch supporters with insults like "running dog," "traitor," "get out!," and "I love the Communist Party." At the same time, about 10 members of the Civil Human Rights Front had orange banners calling for human rights improvements and universal suffrage. Onlookers were saying "Aren't you Chinese?" in Mandarin putonghua as they tried to cover the orange banners with a large Chinese national flag. One woman had an orange sign that said, "Olympic flame for democracy", while a man carried a poster with a tank and the slogan "One world, two dreams". A university student and former RDHK radio host Christina Chan wrapped the Tibetan snow lion flag around her body and later began waving it. Several onlookers heckled Chan, shouting "What kind of Chinese are you?" and "What a shame!" In the end, she and some of the protesters were taken away against their will by the authorities via a police vehicle "for their own protection." Chan is currently[when?] suing the Hong Kong government, claiming her human rights were breached. (case number HCAL139/08)
Who was proud that Hong Kong still has brave people speaking out?
****
The answer: Leung Kwok-hung


Problem: Please answer a question about the following article about Planck constant:
Equivalently, the smallness of the Planck constant reflects the fact that everyday objects and systems are made of a large number of particles. For example, green light with a wavelength of 555 nanometres (the approximate wavelength to which human eyes are most sensitive) has a frequency of 7014540000000000000♠540 THz (7014540000000000000♠540×1012 Hz). Each photon has an energy E = hf = 6981358000000000000♠3.58×10−19 J. That is a very small amount of energy in terms of everyday experience, but everyday experience is not concerned with individual photons any more than with individual atoms or molecules. An amount of light compatible with everyday experience is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, NA ≈ 7023602200000000000♠6.022×1023 mol−1. The result is that green light of wavelength 555 nm has an energy of 7005216000000000000♠216 kJ/mol, a typical energy of everyday life.
What is the frequency of the light to which the human eye is most sensitive?
A: 7014540000000000000♠540 THz


Question: Read this and answer the question

Roncalli was summoned to the final ballot of the conclave at 4:00 pm. He was elected pope at 4:30 pm with a total of 38 votes. After the long pontificate of Pope Pius XII, the cardinals chose a man who – it was presumed because of his advanced age – would be a short-term or "stop-gap" pope. They wished to choose a candidate who would do little during the new pontificate. Upon his election, Cardinal Eugene Tisserant asked him the ritual questions of whether he would accept and if so, what name he would take for himself. Roncalli gave the first of his many surprises when he chose "John" as his regnal name. Roncalli's exact words were "I will be called John". This was the first time in over 500 years that this name had been chosen; previous popes had avoided its use since the time of the Antipope John XXIII during the Western Schism several centuries before.

What name did Roncalli choose?
Answer: John


Problem: Shiraz, with a population of around 1.4 million (2011 census), is the sixth major city of Iran. It is the capital of Fars Province, and was also a former capital of Iran. The area was greatly influenced by the Babylonian civilization, and after the emergence of the ancient Persians, soon came to be known as Persis. Persians were present in the region since the 9th century BC, and became rulers of a large empire under the reign of the Achaemenid Dynasty in the 6th century BC. The ruins of Persepolis and Pasargadae, two of the four capitals of the Achaemenid Empire, are located around the modern-day city of Shiraz.
What is the sixth most populous city of Iran?
The answer is the following: Shiraz


Input: Article: All Iranian languages are descended from a common ancestor, Proto-Iranian. In turn, and together with Proto-Indo-Aryan and the Nuristani languages, Proto-Iranian descends from a common ancestor Proto-Indo-Iranian. The Indo-Iranian languages are thought to have originated in Central Asia. The Andronovo culture is the suggested candidate for the common Indo-Iranian culture ca. 2000 BC.

Now answer this question: When did the Andronovo culture exist?

Output:
2000 BC
