Input: Asphalt
Roofing shingles account for most of the remaining asphalt/bitumen consumption. Other uses include cattle sprays, fence-post treatments, and waterproofing for fabrics. Asphalt/bitumen is used to make Japan black, a lacquer known especially for its use on iron and steel, and it is also used in paint and marker inks by some graffiti supply companies to increase the weather resistance and permanence of the paint or ink, and to make the color much darker.[citation needed] Asphalt/bitumen is also used to seal some alkaline batteries during the manufacturing process.

Besides weather resistance, why else is Japan black used in paints?
Output: permanence

Input: Royal Dutch Shell
Downstream operations, which now also includes the chemicals business, generates a third of Shell's profits worldwide and is known for its global network of more than 40,000 petrol stations and its 47 oil refineries. The downstream business, which in some countries also included oil refining, generally included a retail petrol station network, lubricants manufacture and marketing, industrial fuel and lubricants sales and a host of other product/market sectors such as LPG and bitumen. The practice in Shell was that these businesses were essentially local and that they were best managed by local "operating companies" often with middle and senior management reinforced by expatriates. In the 1990s, this paradigm began to change, and the independence of operating companies around the world was gradually reduced. Today, virtually all of Shell's operations in various businesses are much more directly managed from London and The Hague. The autonomy of "operating companies" has been largely removed, as more "global businesses" have been created.

How many petrol stationsare included in Shell's downstream operations global network?
Output: more than 40,000

Input: Edmund Burke
These events and the disagreements that arose from them within the Whig Party, led to its break-up and to the rupture of Burke's friendship with Fox. In debate in Parliament on Britain's relations with Russia, Fox praised the principles of the revolution, although Burke was not able to reply at this time as he was "overpowered by continued cries of question from his own side of the House". When Parliament was debating the Quebec Bill for a constitution for Canada, Fox praised the revolution and criticised some of Burke's arguments, such as hereditary power. On 6 May 1791, during another debate in Parliament on the Quebec Bill, Burke used the opportunity to answer Fox, and to condemn the new French Constitution and "the horrible consequences flowing from the French idea of the Rights of Man". Burke asserted that those ideas were the antithesis of both the British and the American constitutions. Burke was interrupted, and Fox intervened, saying that Burke should be allowed to carry on with his speech. A vote of censure was moved against Burke, however, for noticing the affairs of France, which was moved by Lord Sheffield and seconded by Fox. Pitt made a speech praising Burke, and Fox made a speechboth rebuking and complimenting Burke. He questioned the sincerity of Burke, who seemed to have forgotten the lessons he had learned from him, quoting from Burke's own speeches of fourteen and fifteen years before.

Fox praised revolutionary principles in a debate about which country?
Output: Russia

Input: Frederic Chopin
Back in Warsaw that year, Chopin heard Niccolo Paganini play the violin, and composed a set of variations, Souvenir de Paganini. It may have been this experience which encouraged him to commence writing his first Etudes, (182932), exploring the capacities of his own instrument. On 11 August, three weeks after completing his studies at the Warsaw Conservatory, he made his debut in Vienna. He gave two piano concerts and received many favourable reviewsin addition to some commenting (in Chopin's own words) that he was "too delicate for those accustomed to the piano-bashing of local artists". In one of these concerts, he premiered his Variations on La ci darem la mano, Op. 2 (variations on an aria from Mozart's opera Don Giovanni) for piano and orchestra. He returned to Warsaw in September 1829, where he premiered his Piano Concerto No. 2 in F minor, Op. 21 on 17 March 1830.

How many weeks after completing school was it before Chopin made his public debut?
