Input: Article: On 25 September, Seoul was recaptured by South Korean forces. American air raids caused heavy damage to the KPA, destroying most of its tanks and much of its artillery. North Korean troops in the south, instead of effectively withdrawing north, rapidly disintegrated, leaving Pyongyang vulnerable. During the general retreat only 25,000 to 30,000 soldiers managed to rejoin the Northern KPA lines. On 27 September, Stalin convened an emergency session of the Politburo, in which he condemned the incompetence of the KPA command and held Soviet military advisers responsible for the defeat.

Now answer this question: What emergency session was called by Stalin?

Output: Politburo


Article: Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, and nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Avivores are animals that are specialized at preying on birds.

Question: What type of birds specialise in hunting mammals or other birds?
Ans: Birds of prey


Here is a question about this article: To allow for agricultural development of the Great Plains and house a growing population, the US passed the Homestead Acts of 1862: it allowed a settler to claim up to 160 acres (65 ha) of land, provided that he lived on it for a period of five years and cultivated it. The provisions were expanded under the Kinkaid Act of 1904 to include a homestead of an entire section. Hundreds of thousands of people claimed such homesteads, sometimes building sod houses out of the very turf of their land. Many of them were not skilled dryland farmers and failures were frequent. Much of the Plains were settled during relatively wet years. Government experts did not understand how farmers should cultivate the prairies and gave advice counter to what would have worked[citation needed]. Germans from Russia who had previously farmed, under similar circumstances, in what is now Ukraine were marginally more successful than other homesteaders. The Dominion Lands Act of 1871 served a similar function for establishing homesteads on the prairies in Canada.
What is the answer to this question: when was the Kinkaid Act brought about? 
****
So... 1904

Problem: Please answer a question about the following article about Intellectual property:
Patent infringement typically is caused by using or selling a patented invention without permission from the patent holder. The scope of the patented invention or the extent of protection is defined in the claims of the granted patent. There is safe harbor in many jurisdictions to use a patented invention for research. This safe harbor does not exist in the US unless the research is done for purely philosophical purposes, or in order to gather data in order to prepare an application for regulatory approval of a drug. In general, patent infringement cases are handled under civil law (e.g., in the United States) but several jurisdictions incorporate infringement in criminal law also (for example, Argentina, China, France, Japan, Russia, South Korea).
What type of law handles patent infringement cases in China?
A: criminal

The first wave of modern Jewish migration to Ottoman-ruled Palestine, known as the First Aliyah, began in 1881, as Jews fled pogroms in Eastern Europe. Although the Zionist movement already existed in practice, Austro-Hungarian journalist Theodor Herzl is credited with founding political Zionism, a movement which sought to establish a Jewish state in the Land of Israel, thus offering a solution to the so-called Jewish Question of the European states, in conformity with the goals and achievements of other national projects of the time. In 1896, Herzl published Der Judenstaat (The State of the Jews), offering his vision of a future Jewish state; the following year he presided over the first Zionist Congress.

Who is credited as founding political Zionism?

Theodor Herzl
