Input: Computer
The CPU contains a special set of memory cells called registers that can be read and written to much more rapidly than the main memory area. There are typically between two and one hundred registers depending on the type of CPU. Registers are used for the most frequently needed data items to avoid having to access main memory every time data is needed. As data is constantly being worked on, reducing the need to access main memory (which is often slow compared to the ALU and control units) greatly increases the computer's speed.

What part of the computer has memory cells called registers?
Output: The CPU


Input: Article: The dynasty was founded by the Jurchen Aisin Gioro clan in Manchuria. In the late sixteenth century, Nurhaci, originally a Ming vassal, began organizing Jurchen clans into "Banners", military-social units. Nurhaci formed these clans into a unified entity, the subjects of which became known collectively as the Manchu people. By 1636, his son Hong Taiji began driving Ming forces out of Liaodong and declared a new dynasty, the Qing. In 1644, peasant rebels led by Li Zicheng conquered the Ming capital Beijing. Rather than serve them, Ming general Wu Sangui made an alliance with the Manchus and opened the Shanhai Pass to the Banner Armies led by Prince Dorgon, who defeated the rebels and seized Beijing. The conquest of China proper was not completed until 1683 under the Kangxi Emperor (r. 1661–1722). The Ten Great Campaigns of the Qianlong Emperor from the 1750s to the 1790s extended Qing control into Central Asia. While the early rulers maintained their Manchu ways, and while their official title was Emperor they were known as khans to the Mongols and patronized Tibetan Buddhism, they governed using Confucian styles and institutions of bureaucratic government. They retained the imperial examinations to recruit Han Chinese to work under or in parallel with Manchus. They also adapted the ideals of the tributary system in international relations, and in places such as Taiwan, the Qing so-called internal foreign policy closely resembled colonial policy and control.

Now answer this question: Where did this dynasty form?

Output: Manchuria


Article: In 1927, the Kuomintang (KMT; Nationalist Party) under Generalissimo Chiang Kai-shek again established Nanjing as the capital of the Republic of China, and this became internationally recognized once KMT forces took Beijing in 1928. The following decade is known as the Nanking decade.

Question: When did the Kuomintang (KMT; Nationalist Party) defeat and take over Beijing?
Ans: 1928


Here is a question about this article: In Argentina, the most representative Carnival performed is the so-called Murga, although other famous Carnivals, more like Brazil's, are held in Argentine Mesopotamia and the North-East. Gualeguaychú in the east of Entre Ríos province is the most important Carnival city and has one of the largest parades. It adopts a musical background similar to Brazilian or Uruguayan Carnival. Corrientes is another city with a Carnival tradition. Chamame is a popular musical style. In all major cities and many towns throughout the country, Carnival is celebrated.
What is the answer to this question: What is Chamame?
****
So... popular musical style.


The problem: Answer a question about this article:
Paper at this point is uncoated. Coated paper has a thin layer of material such as calcium carbonate or china clay applied to one or both sides in order to create a surface more suitable for high-resolution halftone screens. (Uncoated papers are rarely suitable for screens above 150 lpi.) Coated or uncoated papers may have their surfaces polished by calendering. Coated papers are divided into matte, semi-matte or silk, and gloss. Gloss papers give the highest optical density in the printed image.
What papers give the best optical density?
****
The answer: Gloss


The problem: Answer a question about this article:
Technologies based upon the polymerase chain reaction (PCR) method will become nearly ubiquitous gold standards of diagnostics of the near future, for several reasons. First, the catalog of infectious agents has grown to the point that virtually all of the significant infectious agents of the human population have been identified. Second, an infectious agent must grow within the human body to cause disease; essentially it must amplify its own nucleic acids in order to cause a disease. This amplification of nucleic acid in infected tissue offers an opportunity to detect the infectious agent by using PCR. Third, the essential tools for directing PCR, primers, are derived from the genomes of infectious agents, and with time those genomes will be known, if they are not already.
What has the catalog of infectious agents grown to the point of?
****
The answer:
virtually all of the significant infectious agents of the human population have been identified
