Problem: Transistor:

Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p–n–p transistor). This construction produces two p–n junctions: a base–emitter junction and a base–collector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).

What is the name for a layer of n-type semiconductor set between two p-type semiconductors?
---
A: p–n–p transistor


Problem: In 1758, the general of the Hindu Maratha Empire, Raghunath Rao conquered Lahore and Attock. Timur Shah Durrani, the son and viceroy of Ahmad Shah Abdali, was driven out of Punjab. Lahore, Multan, Dera Ghazi Khan, Kashmir and other subahs on the south and eastern side of Peshawar were under the Maratha rule for the most part. In Punjab and Kashmir, the Marathas were now major players. The Third Battle of Panipat took place on 1761, Ahmad Shah Abdali invaded the Maratha territory of Punjab and captured remnants of the Maratha Empire in Punjab and Kashmir regions and re-consolidated control over them.
When did Timur conquer Lahore?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The terms upper case and lower case can be written as two consecutive words, connected with a hyphen (upper-case and lower-case), or as a single word (uppercase and lowercase). These terms originated from the common layouts of the shallow drawers called type cases used to hold the movable type for letterpress printing. Traditionally, the capital letters were stored in a separate case that was located above the case that held the small letters, and the name proved easy to remember since capital letters are taller.
The terms uppercase and lowercase originated from the common layout which type of drawers?
A: shallow


Context and question: Von Neumann's habilitation was completed on December 13, 1927, and he started his lectures as a privatdozent at the University of Berlin in 1928. By the end of 1927, von Neumann had published twelve major papers in mathematics, and by the end of 1929, thirty-two papers, at a rate of nearly one major paper per month. His reputed powers of speedy, massive memorization and recall allowed him to recite volumes of information, and even entire directories, with ease. In 1929, he briefly became a privatdozent at the University of Hamburg, where the prospects of becoming a tenured professor were better, but in October of that year a better offer presented itself when he was invited to Princeton University in Princeton, New Jersey.
By the end of 1927 how many papers had Von Neuman written?
Answer: twelve major papers in mathematics


Question: In the judgment of political scientist Randall Ripley, since 1883 "the candidate for Speaker nominated by the minority party has clearly been the Minority Leader." However, this assertion is subject to dispute. On December 3, 1883, the House elected Democrat John G. Carlisle of Kentucky as Speaker. Republicans placed in nomination for the speakership J. Warren Keifer of Ohio, who was Speaker the previous Congress. Clearly, Keifer was not the Republicans' minority leader. He was a discredited leader in part because as Speaker he arbitrarily handed out "choice jobs to close relatives ... all at handsome salaries." Keifer received "the empty honor of the minority nomination. But with it came a sting -- for while this naturally involves the floor leadership, he was deserted by his [partisan] associates and his career as a national figure terminated ingloriously." Representative Thomas Reed, R-ME, who later became Speaker, assumed the de facto role of minority floor leader in Keifer's stead. "[A]lthough Keifer was the minority's candidate for Speaker, Reed became its acknowledged leader, and ever after, so long as he served in the House, remained the most conspicuous member of his party.
Is there an answer to this question: What happened to Ripley's career becaue of this desertion?

Answer: unanswerable


QUES: A distinction can be made between emotional episodes and emotional dispositions. Emotional dispositions are also comparable to character traits, where someone may be said to be generally disposed to experience certain emotions. For example, an irritable person is generally disposed to feel irritation more easily or quickly than others do. Finally, some theorists place emotions within a more general category of "affective states" where affective states can also include emotion-related phenomena such as pleasure and pain, motivational states (for example, hunger or curiosity), moods, dispositions and traits.

What category is defined to contain pleasure, pain, motivation, moods and dispositions?
What is the answer?
ANS:
affective states
