Article: In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]

Question: What was the Chopin family's business?

Article: Like other American research universities, Northwestern was transformed by World War II. Franklyn B. Snyder led the university from 1939 to 1949, when nearly 50,000 military officers and personnel were trained on the Evanston and Chicago campuses. After the war, surging enrollments under the G.I. Bill drove drastic expansion of both campuses. In 1948 prominent anthropologist Melville J. Herskovits founded the Program of African Studies at Northwestern, the first center of its kind at an American academic institution. J. Roscoe Miller's tenure as president from 1949 to 1970 was responsible for the expansion of the Evanston campus, with the construction of the lakefill on Lake Michigan, growth of the faculty and new academic programs, as well as polarizing Vietnam-era student protests. In 1978, the first and second Unabomber attacks occurred at Northwestern University. Relations between Evanston and Northwestern were strained throughout much of the post-war era because of episodes of disruptive student activism, disputes over municipal zoning, building codes, and law enforcement, as well as restrictions on the sale of alcohol near campus until 1972. Northwestern's exemption from state and municipal property tax obligations under its original charter has historically been a source of town and gown tension.

Question: In 1978, what famous attacks occured at Northwestern?
Ans: first and second Unabomber


Article: The post-Mughal era was dominated by the rise of the Maratha suzerainty as other small regional states (mostly late Mughal tributary states) emerged, and also by the increasing activities of European powers. There is no doubt that the single most important power to emerge in the long twilight of the Mughal dynasty was the Maratha confederacy. The Maratha kingdom was founded and consolidated by Chatrapati Shivaji, a Maratha aristocrat of the Bhonsle clan who was determined to establish Hindavi Swarajya. Sir J.N. Sarkar described Shivaji as "the last great constructive genius and nation builder that the Hindu race has produced". However, the credit for making the Marathas formidable power nationally goes to Peshwa Bajirao I. Historian K.K. Datta wrote about Bajirao I:

Question: The rise of what dynasty followed the era of the Mughals?
Ans: Maratha suzerainty


Article: Electric recording which developed during the time that early radio was becoming popular (1925) benefited from the microphones and amplifiers used in radio studios. The early electric recordings were reminiscent tonally of acoustic recordings, except there was more recorded bass and treble as well as delicate sounds and overtones cut on the records. This was in spite of some carbon microphones used, which had resonances that colored the recorded tone. The double button carbon microphone with stretched diaphragm was a marked improvement. Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones.

Question: What type of microphones were losing popularity in the 1920s?
Ans:
carbon microphones used,
