During the 1930s, the first two motorways were built across the Land, the A4 motorway as an important east-west connection in central Germany and the main link between Berlin and south-west Germany, and the A9 motorway as the main north-south route in eastern Germany, connecting Berlin with Munich. The A4 runs from Frankfurt in Hesse via Eisenach, Gotha, Erfurt, Weimar, Jena and Gera to Dresden in Saxony, connecting Thuringia's most important cities. At Hermsdorf junction it is connected with the A9. Both highways were widened from four to six lanes (three each way) after 1990, including some extensive re-routing in the Eisenach and Jena areas. Furthermore, three new motorways were built during the 1990s and 2000s. The A71 crosses the Land in southwest-northeast direction, connecting Wurzburg in Bavaria via Meiningen, Suhl, Ilmenau, Arnstadt, Erfurt and Sommerda with Sangerhausen and Halle in Saxony-Anhalt. The crossing of the Thuringian Forest by the A71 has been one of Germany's most expensive motorway segments with various tunnels (including Germany's longest road tunnel, the Rennsteig Tunnel) and large bridges. The A73 starts at the A71 south of Erfurt in Suhl and runs south towards Nuremberg in Bavaria. The A38 is another west-east connection in the north of Thuringia running from Gottingen in Lower Saxony via Heiligenstadt and Nordhausen to Leipzig in Saxony. Furthermore, there is a dense network of federal highways complementing the motorway network. The upgrading of federal highways is prioritised in the federal trunk road programme 2015 (Bundesverkehrswegeplan 2015). Envisaged projects include upgrades of the B247 from Gotha to Leinefelde to improve Muhlhausen's connection to the national road network, the B19 from Eisenach to Meiningen to improve access to Bad Salzungen and Schmalkalden, and the B88 and B281 for strengthening the Saalfeld/Rudolstadt region.

Since October 2004, the iPod line has dominated digital music player sales in the United States, with over 90% of the market for hard drive-based players and over 70% of the market for all types of players. During the year from January 2004 to January 2005, the high rate of sales caused its U.S. market share to increase from 31% to 65% and in July 2005, this market share was measured at 74%. In January 2007 the iPod market share reached 72.7% according to Bloomberg Online.
Approximately what percentage of the hard drive-based music player sales does iPod have since 2004?
A: 90%

Hayek's influence on the development of economics is widely acknowledged. Hayek is the second-most frequently cited economist (after Kenneth Arrow) in the Nobel lectures of the prize winners in economics, which is particularly striking since his own lecture was critical of the field of orthodox economics and neo-classical modelisation. A number of Nobel Laureates in economics, such as Vernon Smith and Herbert A. Simon, recognise Hayek as the greatest modern economist. Another Nobel winner, Paul Samuelson, believed that Hayek was worthy of his award but nevertheless claimed that "there were good historical reasons for fading memories of Hayek within the mainstream last half of the twentieth century economist fraternity. In 1931, Hayek's Prices and Production had enjoyed an ultra-short Byronic success. In retrospect hindsight tells us that its mumbo-jumbo about the period of production grossly misdiagnosed the macroeconomics of the 19271931 (and the 19312007) historical scene". Despite this comment, Samuelson spent the last 50 years of his life obsessed with the problems of capital theory identified by Hayek and Bohm-Bawerk, and Samuelson flatly judged Hayek to have been right and his own teacher, Joseph Schumpeter, to have been wrong on the central economic question of the 20th century, the feasibility of socialist economic planning in a production goods dominated economy.
What Nobel prize winner has spent most of his life studying Hayek's capital theory despite being critical of the man?
A: Paul Samuelson

J. Barrie Jones suggests that "amongst the works that Chopin intended for concert use, the four ballades and four scherzos stand supreme", and adds that "the Barcarolle Op. 60 stands apart as an example of Chopin's rich harmonic palette coupled with an Italianate warmth of melody." Temperley opines that these works, which contain "immense variety of mood, thematic material and structural detail", are based on an extended "departure and return" form; "the more the middle section is extended, and the further it departs in key, mood and theme, from the opening idea, the more important and dramatic is the reprise when it at last comes."
What piece does J. Barrie Jones pinpoint as a great example of Chopin's palette?
A:
the Barcarolle Op. 60
