On 30 September, Zhou Enlai warned the United States that China was prepared to intervene in Korea if the United States crossed the 38th parallel. Zhou attempted to advise North Korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed Chinese communist forces to successfully escape Chiang Kai-shek's Encirclement Campaigns in the 1930s, but by some accounts North Korean commanders did not utilize these tactics effectively. Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts.
What may have been North Korea's goal in the way they rapidly withdrew from South Korea?
launch guerrilla raids

Input: Article: The desert zone also accounts for about a third of the state's surface area. The Chihuahuan Desert is an international biome that also extends into the neighboring Mexican state of Coahuila and into the U.S. states of Texas and New Mexico. The desert zone is mainly of flat topography with some small mountain ranges that run north to south. The desert in the state varies slightly with a small variant in climate. The lower elevations of the desert zone are found in the north along the Rio Grande which experience hotter temperatures in the summer and winter while the southern portion of the desert zone experiences cooler temperatures due to its higher elevation. The Samalayuca dunes cover an area of about 150 km2; it is an impressive site of the Chihuahuan Desert and is a protected area by the state due to unique species of plants and animals.

Now answer this question: The Chihuahuan Desert also extends into which neighboring Mexican state?

Output: Coahuila

Article: Theories given for the success of Southerners on Idol have been: more versatility with musical genres, as the Southern U.S. is home to several music genre scenes; not having as many opportunities to break into the pop music business; text-voting due to the South having the highest percentage of cell-phone only households; and the strong heritage of music and singing, which is notable in the Bible Belt, where it is in church that many people get their start in public singing. Others also suggest that the Southern character of these contestants appeal to the South, as well as local pride. According to season five winner Taylor Hicks, who is from the state of Alabama, "People in the South have a lot of pride ... So, they're adamant about supporting the contestants who do well from their state or region."

Question: What state is Taylor Hicks from?
Ans: Alabama

Here is a question about this article: In 2008 renewable energy accounted for 8% of the country's total energy consumption, a rise from the 7.2% it accounted for in 2006, but still below the EU average of 10% in 2008. 10% of the country's renewable energy comes from solar power, while most comes from biomass and waste recycling. In line with the European Commission's Directive on Renewable Energy, Greece aims to get 18% of its energy from renewable sources by 2020. In 2013 and for several months, Greece produced more than 20% of its electricity from renewable energy sources and hydroelectric power plants. Greece currently does not have any nuclear power plants in operation, however in 2009 the Academy of Athens suggested that research in the possibility of Greek nuclear power plants begin.
What is the answer to this question: How much of Greece's energy is targeted to be from renewable sources by 2020?
****
So... 18%

Article: Like other historical languages, Old English has been used by scholars and enthusiasts of later periods to create texts either imitating Anglo-Saxon literature or deliberately transferring it to a different cultural context. Examples include Alistair Campbell and J. R. R. Tolkien. A number of websites devoted to Neo-Paganism and Historical re-enactment offer reference material and forums promoting the active use of Old English. By far the most ambitious project[peacock term] is the Old English Wikipedia, but most of the Neo-Old English texts published online bear little resemblance to the historical model and are riddled with very basic grammatical mistakes.

Question: What Wikipedia project makes use of the Old English language?
Ans:
the Old English Wikipedia
