Q: Passage: Born to an aristocratic family in Ithaca, Metaxas took part in the Greco-Turkish War of 1897 and the Balkan Wars (1912–13), quickly rising through the ranks of the Hellenic Army. A royalist during the National Schism, Metaxas unsuccessfully opposed Prime Minister Eleftherios Venizelos and Greece's entry in World War I; as a result, he was exiled to Corsica in 1917. On his return, Metaxas moved into politics and founded the Freethinkers' Party, but had only limited success under the Hellenic Republic. The Greek monarchy was restored in 1935, and Metaxas was appointed Prime Minister in April 1936. On 4 August 1936, with the support of King George II, Metaxas initiated a self-coup and established an authoritarian, nationalist and anti-communist regime.
 Link Information: George II (, Geórgios II; 19 July 1890 (NS) – 1 April 1947) reigned as King of Greece from 1922 to 1924 and from 1935 to 1947 Question: What time period did George II serve as king?

A: Answer: from 1922 to 1924 and from 1935 to 1947

Q: Passage: Walt Disney engaged O'Malley to provide voices for animated films such as the Cockney coster in the "Supercalifragilisticexpialidocious" sequence in Mary Poppins (1964); Cyril Proudbottom, Winkie, and a policeman in The Adventures of Ichabod and Mr. Toad (1949); and the role of Colonel Hathi and the vulture Buzzie in The Jungle Book (1967). His voice can be heard in Alice in Wonderland (1951), in which he performs all the character voices in "The Walrus and the Carpenter" segment (besides Alice), including Tweedledum and Tweedledee, the Walrus, the Carpenter, and Mother Oyster. O'Malley also provided the voice of Br'er Fox in Song of the South (1946) when James Baskett was unavailable. Actor Dick Van Dyke has said that O'Malley was his dialect coach on Mary Poppins, attributing his infamous Cockney accent in that film to O'Malley.
 Link Information: That same year, Van Dyke was cast in two roles: as the chimney sweep Bert, and as bank chairman Mr. Dawes Senior, in Walt Disney's Mary Poppins (1964).  Question: What role did Dick Van Dyke play in Mary Poppins?

A: Answer: the chimney sweep Bert, and as bank chairman Mr. Dawes Senior

Q: 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.
