Problem: In 1877, Thomas Edison invented the phonograph. Unlike the phonautograph, it was capable of both recording and reproducing sound. Despite the similarity of name, there is no documentary evidence that Edison's phonograph was based on Scott's phonautograph. Edison first tried recording sound on a wax-impregnated paper tape, with the idea of creating a "telephone repeater" analogous to the telegraph repeater he had been working on. Although the visible results made him confident that sound could be physically recorded and reproduced, his notes do not indicate that he actually reproduced sound before his first experiment in which he used tinfoil as a recording medium several months later. The tinfoil was wrapped around a grooved metal cylinder and a sound-vibrated stylus indented the tinfoil while the cylinder was rotated. The recording could be played back immediately. The Scientific American article that introduced the tinfoil phonograph to the public mentioned Marey, Rosapelly and Barlow as well as Scott as creators of devices for recording but, importantly, not reproducing sound. Edison also invented variations of the phonograph that used tape and disc formats. Numerous applications for the phonograph were envisioned, but although it enjoyed a brief vogue as a startling novelty at public demonstrations, the tinfoil phonograph proved too crude to be put to any practical use. A decade later, Edison developed a greatly improved phonograph that used a hollow wax cylinder instead of a foil sheet. This proved to be both a better-sounding and far more useful and durable device. The wax phonograph cylinder created the recorded sound market at the end of the 1880s and dominated it through the early years of the 20th century.
How did the phonograph differ from the phonautograph?
The answer is the following: capable of both recording and reproducing sound

Input: Emotion
There are some theories on emotions arguing that cognitive activity in the form of judgments, evaluations, or thoughts are necessary in order for an emotion to occur. A prominent philosophical exponent is Robert C. Solomon (for example, The Passions, Emotions and the Meaning of Life, 1993). Solomon claims that emotions are judgments. He has put forward a more nuanced view which response to what he has called the 'standard objection' to cognitivism, the idea that a judgment that something is fearsome can occur with or without emotion, so judgment cannot be identified with emotion. The theory proposed by Nico Frijda where appraisal leads to action tendencies is another example.

What does Solomon believe emotions to be?
Output: judgments

Input: Article: In studying adolescent development, adolescence can be defined biologically, as the physical transition marked by the onset of puberty and the termination of physical growth; cognitively, as changes in the ability to think abstractly and multi-dimensionally; or socially, as a period of preparation for adult roles. Major pubertal and biological changes include changes to the sex organs, height, weight, and muscle mass, as well as major changes in brain structure and organization. Cognitive advances encompass both increases in knowledge and in the ability to think abstractly and to reason more effectively. The study of adolescent development often involves interdisciplinary collaborations. For example, researchers in neuroscience or bio-behavioral health might focus on pubertal changes in brain structure and its effects on cognition or social relations. Sociologists interested in adolescence might focus on the acquisition of social roles (e.g., worker or romantic partner) and how this varies across cultures or social conditions. Developmental psychologists might focus on changes in relations with parents and peers as a function of school structure and pubertal status.

Now answer this question: How is adolescence defined socially?

Output: a period of preparation for adult roles

Article: Throughout the 19th century, Philadelphia had a variety of industries and businesses, the largest being textiles. Major corporations in the 19th and early 20th centuries included the Baldwin Locomotive Works, William Cramp and Sons Ship and Engine Building Company, and the Pennsylvania Railroad. Industry, along with the U.S. Centennial, was celebrated in 1876 with the Centennial Exposition, the first official World's Fair in the United States. Immigrants, mostly Irish and German, settled in Philadelphia and the surrounding districts. The rise in population of the surrounding districts helped lead to the Act of Consolidation of 1854, which extended the city limits of Philadelphia from the 2 square miles of present-day Center City to the roughly 130 square miles of Philadelphia County.

Question: What was Philadelphia's biggest industry during the 19th century?
Ans: textiles

Input: Sino-Tibetan relations during the Ming dynasty
Discussions of strategy in the mid Ming dynasty focused primarily on recovery of the Ordos region, which the Mongols used as a rallying base to stage raids into Ming China. Norbu states that the Ming dynasty, preoccupied with the Mongol threat to the north, could not spare additional armed forces to enforce or back up their claim of sovereignty over Tibet; instead, they relied on "Confucian instruments of tribute relations" of heaping unlimited number of titles and gifts on Tibetan lamas through acts of diplomacy. Sperling states that the delicate relationship between the Ming and Tibet was "the last time a united China had to deal with an independent Tibet," that there was a potential for armed conflict at their borders, and that the ultimate goal of Ming foreign policy with Tibet was not subjugation but "avoidance of any kind of Tibetan threat." P. Christiaan Klieger argues that the Ming court's patronage of high Tibetan lamas "was designed to help stabilize border regions and protect trade routes."

Why did P. Christiaan Klieger believe that the Ming court supported high Tibetan lamas?
Output:
to help stabilize border regions and protect trade routes
