Problem: Copper:

The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur.

What metal has a higher thermal conductivity than copper?

A: silver


Problem: The prevalence of phantom pain in upper limb amputees is nearly 82%, and in lower limb amputees is 54%. One study found that eight days after amputation, 72 percent of patients had phantom limb pain, and six months later, 65 percent reported it. Some amputees experience continuous pain that varies in intensity or quality; others experience several bouts a day, or it may occur only once every week or two. It is often described as shooting, crushing, burning or cramping. If the pain is continuous for a long period, parts of the intact body may become sensitized, so that touching them evokes pain in the phantom limb, or phantom limb pain may accompany urination or defecation.
What did 65% of patients report eight months after amputation?

One of Hyderabad's earliest newspapers, The Deccan Times, was established in the 1780s. In modern times, the major Telugu dailies published in Hyderabad are Eenadu, Andhra Jyothy, Sakshi and Namaste Telangana, while the major English papers are The Times of India, The Hindu and The Deccan Chronicle. The major Urdu papers include The Siasat Daily, The Munsif Daily and Etemaad. Many coffee table magazines, professional magazines and research journals are also regularly published. The Secunderabad Cantonment Board established the first radio station in Hyderabad State around 1919. Deccan Radio was the first radio public broadcast station in the city starting on 3 February 1935, with FM broadcasting beginning in 2000. The available channels in Hyderabad include All India Radio, Radio Mirchi, Radio City, Red FM and Big FM.
When was The Deccan Times founded?
A: the 1780s


Context and question: After years of high increase, the unemployment in Portugal has been in a continuous falling trend since the third quarter of 2014, decreasing from a peak of 17.7% achieved in the early 2013 to a rate of 11.9% in the second quarter of 2015. However, it is high still high compared with what was the normal average Portuguese unemployment rate in the past. In the second quarter of 2008 the unemployment rate was 7.3%, but the rate immediately rose the following period. By December 2009, unemployment had surpassed the 10% mark nationwide in the wake of worldwide events, by 2010, the rate was around 11% and in 2011 it was above 12%.[citation needed] The first quarter of 2013 signified a new unemployment rate record for Portugal, as it reached 17.7%— up from 17% in the previous quarter — and the Government has predicted an 18.5% unemployment rate in 2014. However, in the third quarter of the same year, it has surprisingly declined to a rate of 15.6%. From then on, the unemployment downtrend continued, declining to 13.9% in the second semester of 2014 and to 11.9% in the second quarter of 2015.
Since when has the Portugal unemployment rate been in a falling trend?
Answer: third quarter of 2014


Question: Burke was not merely presenting a peace agreement to Parliament; rather, he stepped forward with four reasons against using force, carefully reasoned. He laid out his objections in an orderly manner, focusing on one before moving to the next. His first concern was that the use of force would have to be temporary, and that the uprisings and objections to British governance in America would not be. Second, Burke worried about the uncertainty surrounding whether Britain would win a conflict in America. "An armament", Burke said, "is not a victory". Third, Burke brought up the issue of impairment; it would do the British Government no good to engage in a scorched earth war and have the object they desired (America) become damaged or even useless. The American colonists could always retreat into the mountains, but the land they left behind would most likely be unusable, whether by accident or design. The fourth and final reason to avoid the use of force was experience; the British had never attempted to rein in an unruly colony by force, and they did not know if it could be done, let alone accomplished thousands of miles away from home. Not only were all of these concerns reasonable, but some turned out to be prophetic – the American colonists did not surrender, even when things looked extremely bleak, and the British were ultimately unsuccessful in their attempts to win a war fought on American soil.
Is there an answer to this question: How many reasons in favor of the use of force did Burke present?

Answer: unanswerable


Question: Three-phase AC railway electrification was used in Italy, Switzerland and the United States in the early twentieth century. Italy was the major user, for lines in the mountainous regions of northern Italy from 1901 until 1976. The first lines were the Burgdorf-Thun line in Switzerland (1899), and the lines of the Ferrovia Alta Valtellina from Colico to Chiavenna and Tirano in Italy, which were electrified in 1901 and 1902. Other lines where the three-phase system were used were the Simplon Tunnel in Switzerland from 1906 to 1930, and the Cascade Tunnel of the Great Northern Railway in the United States from 1909 to 1927.
Is there an answer to this question: What country was a bigger user compare to the three of them?

Answer:
Italy
