Four boarders at his parents' apartments became Chopin's intimates: Tytus Woyciechowski, Jan Nepomucen Biaobocki, Jan Matuszynski and Julian Fontana; the latter two would become part of his Paris milieu. He was friendly with members of Warsaw's young artistic and intellectual world, including Fontana, Jozef Bohdan Zaleski and Stefan Witwicki. He was also attracted to the singing student Konstancja Gadkowska. In letters to Woyciechowski, he indicated which of his works, and even which of their passages, were influenced by his fascination with her; his letter of 15 May 1830 revealed that the slow movement (Larghetto) of his Piano Concerto No. 1 (in E minor) was secretly dedicated to her "It should be like dreaming in beautiful springtime by moonlight." His final Conservatory report (July 1829) read: "Chopin F., third-year student, exceptional talent, musical genius."

What musical piece had a Larghetto dedicated to the female singing student Chopin was infatuated with?
Output: Piano Concerto No. 1 (in E minor)

Input: Article: Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.

Now answer this question: What object is used to expose selected parts of the photosensitive film to light?

Output: mask

Article: By 1353, the three original cantons had joined with the cantons of Glarus and Zug and the Lucerne, Zurich and Bern city states to form the "Old Confederacy" of eight states that existed until the end of the 15th century. The expansion led to increased power and wealth for the federation. By 1460, the confederates controlled most of the territory south and west of the Rhine to the Alps and the Jura mountains, particularly after victories against the Habsburgs (Battle of Sempach, Battle of Nafels), over Charles the Bold of Burgundy during the 1470s, and the success of the Swiss mercenaries. The Swiss victory in the Swabian War against the Swabian League of Emperor Maximilian I in 1499 amounted to de facto independence within the Holy Roman Empire.

Question: By 1460, who controlled most of the territory south and west of the Rhine?
Ans: the confederates

Input: Qing dynasty
Demand in Europe for Chinese goods such as silk, tea, and ceramics could only be met if European companies funneled their limited supplies of silver into China. In the late 1700s, the governments of Britain and France were deeply concerned about the imbalance of trade and the drain of silver. To meet the growing Chinese demand for opium, the British East India Company greatly expanded its production in Bengal. Since China's economy was essentially self-sufficient, the country had little need to import goods or raw materials from the Europeans, so the usual way of payment was through silver. The Daoguang Emperor, concerned both over the outflow of silver and the damage that opium smoking was causing to his subjects, ordered Lin Zexu to end the opium trade. Lin confiscated the stocks of opium without compensation in 1839, leading Britain to send a military expedition the following year.

What products from China did Europeans want?
Output:
silk, tea, and ceramics
