question:
Question: How many people live in the city where Stevens grew up? Passage:Stevens grew up in Sydney and was an accountant and public servant before entering politics. He was elected to the New South Wales Legislative Assembly at the 1927 state election, as a member of the Nationalist Party. In 1929, he was appointed state treasurer under Thomas Bavin, serving until his party lost the 1930 election. In 1932, Stevens was elected as the inaugural leader of the state branch of the UAP. He became premier later that year, following the dismissal of Labor's Jack Lang, and subsequently led his party to victory at the 1932, 1935, and 1938 elections. Stevens was ousted in 1939 and replaced by Alexander Mair. He made an abortive attempt to enter federal politics at the 1940 election, and thereafter played little part in public life.

answer:
Stevens grew up in Sydney and was an accountant and public servant before entering politics


question:
Question: How old is the city where Herz was born? Passage:Born in Berlin to very poor parents, Herz was destined for a mercantile career, and in 1762 went to Königsberg, East Prussia. He soon gave up his position as clerk and attended the University of Königsberg, becoming a pupil of Immanuel Kant, but was obliged to discontinue his studies for want of means. He thereupon became secretary to the wealthy Russian Ephraim, traveling with him through the Baltic Provinces. On August 21, 1770, he traveled from Berlin and acted as respondent when Kant presented his Inaugural dissertation at the University of Königsberg for the post of ordinary professor. In 1770 he had returned to Germany and studied medicine in Halle, where he became an MD in 1774, in which year he established himself in Berlin, being appointed physician at the Jewish hospital. Beginning in 1777, he delivered public lectures on medicine and philosophy, which were well attended by the students and the principal personages of the Prussian capital. At some of them even members of the royal family were present.

answer:
Born in Berlin to very poor parents, Herz was destined for a mercantile career, and in 1762 went to Königsberg, East Prussia


question:
Question: Did spark gap transmitters have any uses after radio transmitters replaced them? Passage:The discovery of the triode's amplifying ability in 1912 revolutionized electrical technology, creating the new field of electronics, the technology of active (amplifying) electrical devices. The triode was immediately applied to many areas of communication. Triode "continuous wave" radio transmitters replaced the cumbersome inefficient "damped wave" spark gap transmitters, allowing the transmission of sound by amplitude modulation (AM). Amplifying triode radio receivers, which had the power to drive loudspeakers, replaced weak crystal radios, which had to be listened to with earphones, allowing families to listen together. This resulted in the evolution of radio from a commercial message service to the first mass communication medium, with the beginning of radio broadcasting around 1920. Triodes made transcontinental telephone service possible. Vacuum tube triode repeaters, invented at Bell Telephone after its purchase of the Audion rights, allowed telephone calls to travel beyond the unamplified limit of about 800 miles. The opening by Bell of the first transcontinental telephone line was celebrated 3 years later, on January 25, 1915. Other inventions made possible by the triode were television, public address systems, electric phonographs, and talking motion pictures.

answer:

Triode "continuous wave" radio transmitters replaced the cumbersome inefficient "damped wave" spark gap transmitters, allowing the transmission of sound by amplitude modulation (AM)
