Input: Transistor
In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.

How are parameters chosen in a switching circuit?
Output: the "off" output is limited to leakage currents too small to affect connected circuitry


Input: Article: What's New was announced at Gamescom 2009 and was released on September 1, 2009, with PlayStation 3 system software 3.0. The feature was to replace the existing [Information Board], which displayed news from the PlayStation website associated with the user's region. The concept was developed further into a major PlayStation Network feature, which interacts with the [Status Indicator] to display a ticker of all content, excluding recently played content (currently in North America and Japan only).

Now answer this question: What type of information is disseminated through What's New?

Output: news


Article: The large external sculptural schemes of Early Gothic churches gave way to more sculpture inside the building, as tombs became more elaborate and other features such as pulpits were sometimes lavishly carved, as in the Pulpit by Giovanni Pisano in Sant'Andrea. Painted or carved wooden relief altarpieces became common, especially as churches created many side-chapels. Early Netherlandish painting by artists such as Jan van Eyck (d. 1441) and Rogier van der Weyden (d. 1464) rivalled that of Italy, as did northern illuminated manuscripts, which in the 15th century began to be collected on a large scale by secular elites, who also commissioned secular books, especially histories. From about 1450 printed books rapidly became popular, though still expensive. There were around 30,000 different editions of incunabula, or works printed before 1500, by which time illuminated manuscripts were commissioned only by royalty and a few others. Very small woodcuts, nearly all religious, were affordable even by peasants in parts of Northern Europe from the middle of the 15th century. More expensive engravings supplied a wealthier market with a variety of images.

Question: What does incunabula refer to?
Ans: works printed before 1500


Here is a question about this article: The Association for Asian Studies states that there is no known written evidence to suggest that later leaders of the Gelug—Gendün Drup (1391–1474) and Gendün Gyatso (1475–1571)—had any contacts with Ming China. These two religious leaders were preoccupied with an overriding concern for dealing with the powerful secular Rinpungpa princes, who were patrons and protectors of the Karma Kargyu lamas. The Rinpungpa leaders were relatives of the Phagmodrupa, yet their authority shifted over time from simple governors to rulers in their own right over large areas of Ü-Tsang. The prince of Rinbung occupied Lhasa in 1498 and excluded the Gelug from attending New Years ceremonies and prayers, the most important event in the Gelug. While the task of New Years prayers in Lhasa was granted to the Karmapa and others, Gendün Gyatso traveled in exile looking for allies. However, it was not until 1518 that the secular Phagmodru ruler captured Lhasa from the Rinbung, and thereafter the Gelug was given rights to conduct the New Years prayer. When the Drikung Kagyu abbot of Drigung Monastery threatened Lhasa in 1537, Gendün Gyatso was forced to abandon the Drepung Monastery, although he eventually returned.
What is the answer to this question: Who were the Rinpungpa leaders related to?
****
So... the Phagmodrupa


The problem: Answer a question about this article:
Dell committed to reduce greenhouse gas emissions from its global activities by 40% by 2015, with 2008 fiscal year as the baseline year. It is listed in Greenpeace’s Guide to Greener Electronics that scores leading electronics manufacturers according to their policies on sustainability, climate and energy and how green their products are. In November 2011, Dell ranked 2nd out of 15 listed electronics makers (increasing its score to 5.1 from 4.9, which it gained in the previous ranking from October 2010).
What emissions did Dell strive to reduce?
****
The answer: greenhouse gas


The problem: Answer a question about this article:
Purely electronic circuit elements soon replaced their mechanical and electromechanical equivalents, at the same time that digital calculation replaced analog. The engineer Tommy Flowers, working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange. Experimental equipment that he built in 1934 went into operation 5 years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes. In the US, John Vincent Atanasoff and Clifford E. Berry of Iowa State University developed and tested the Atanasoff–Berry Computer (ABC) in 1942, the first "automatic electronic digital computer". This design was also all-electronic and used about 300 vacuum tubes, with capacitors fixed in a mechanically rotating drum for memory.
In what city did Tommy Flowers work in the 1930s?
****
The answer:
London
