By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success.[N 14] While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas.
On what material did the phonautograph operate?
smoked glass


Input: Military history of the United States
Following the American Revolutionary War, the United States faced potential military conflict on the high seas as well as on the western frontier. The United States was a minor military power during this time, having only a modest army, Marine corps, and navy. A traditional distrust of standing armies, combined with faith in the abilities of local militia, precluded the development of well-trained units and a professional officer corps. Jeffersonian leaders preferred a small army and navy, fearing that a large military establishment would involve the United States in excessive foreign wars, and potentially allow a domestic tyrant to seize power.

Why was the US military so small initially?
Output: A traditional distrust of standing armies


Input: Article: Today, this term also refers to the doctrines and practices of the Reformed churches of which Calvin was an early leader. Less commonly, it can refer to the individual teaching of Calvin himself. The particulars of Calvinist theology may be stated in a number of ways. Perhaps the best known summary is contained in the five points of Calvinism, though these points identify the Calvinist view on soteriology rather than summarizing the system as a whole. Broadly speaking, Calvinism stresses the sovereignty or rule of God in all things — in salvation but also in all of life. This concept is seen clearly in the doctrines of predestination and total depravity.

Now answer this question: What area does the five points of Calvinism focus on?

Output: the Calvinist view on soteriology


Article: At launch, the Xbox 360 was available in two configurations: the "Xbox 360" package (unofficially known as the 20 GB Pro or Premium), priced at US$399 or GB£279.99, and the "Xbox 360 Core", priced at US$299 and GB£209.99. The original shipment of the Xbox 360 version included a cut-down version of the Media Remote as a promotion. The Elite package was launched later at US$479. The "Xbox 360 Core" was replaced by the "Xbox 360 Arcade" in October 2007 and a 60 GB version of the Xbox 360 Pro was released on August 1, 2008. The Pro package was discontinued and marked down to US$249 on August 28, 2009 to be sold until stock ran out, while the Elite was also marked down in price to US$299.

Question: The 360 Pro's original storage was replaced by a hard drive of what size in 2008?
Ans: 60 GB


Here is a question about this article: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
What is the answer to this question: What was realized after Planck's discovery?
****
So... that physical action cannot take on an arbitrary value


Article: The KU men's basketball team has fielded a team every year since 1898. The Jayhawks are a perennial national contender currently coached by Bill Self. The team has won five national titles, including three NCAA tournament championships in 1952, 1988, and 2008. The basketball program is currently the second winningest program in college basketball history with an overall record of 2,070–806 through the 2011–12 season. The team plays at Allen Fieldhouse. Perhaps its best recognized player was Wilt Chamberlain, who played in the 1950s. Kansas has counted among its coaches Dr. James Naismith (the inventor of basketball and only coach in Kansas history to have a losing record), Basketball Hall of Fame inductee Phog Allen ("the Father of basketball coaching"), Basketball Hall of Fame inductee Roy Williams of the University of North Carolina at Chapel Hill, and Basketball Hall of Fame inductee and former NBA Champion Detroit Pistons coach Larry Brown. In addition, legendary University of Kentucky coach and Basketball Hall of Fame inductee Adolph Rupp played for KU's 1922 and 1923 Helms National Championship teams, and NCAA Hall of Fame inductee and University of North Carolina Coach Dean Smith played for KU's 1952 NCAA Championship team. Both Rupp and Smith played under Phog Allen. Allen also coached Hall of Fame coaches Dutch Lonborg and Ralph Miller. Allen founded the National Association of Basketball Coaches (NABC), which started what is now the NCAA Tournament. The Tournament began in 1939 under the NABC and the next year was handed off to the newly formed NCAA.

Question: How many times has the University of Kansas won a national championship in men's basketball?
Ans:
five
