Problem: A collector of film memorabilia, Spielberg purchased a balsa Rosebud sled from Citizen Kane (1941) in 1982. He bought Orson Welles's own directorial copy of the script for the radio broadcast The War of the Worlds (1938) in 1994. Spielberg has purchased Academy Award statuettes being sold on the open market and donated them to the Academy of Motion Picture Arts and Sciences, to prevent their further commercial exploitation. His donations include the Oscars that Bette Davis received for Dangerous (1935) and Jezebel (1938), and Clark Gable's Oscar for It Happened One Night (1934).
In what year did Spielberg buy his first open market Academy Award?

Problem: During the reign of Mithridates I of Parthia, Arsacid control expanded to include Herat (in 167 BC), Babylonia (in 144 BC), Media (in 141 BC), Persia (in 139 BC), and large parts of Syria (in the 110s BC). The SeleucidParthian wars continued as the Seleucids invaded Mesopotamia under Antiochus VII Sidetes (r. 138129 BC), but he was eventually killed by a Parthian counterattack. After the fall of the Seleucid dynasty, the Parthians fought frequently against neighbouring Rome in the RomanParthian Wars (66 BC 217 AD). Abundant traces of Hellenism continued under the Parthian empire. The Parthians used Greek as well as their own Parthian language (though lesser than Greek) as languages of administration and also used Greek drachmas as coinage. They enjoyed Greek theater and Greek art influenced Parthian art. The Parthians continued worhipping Greek gods syncretized together with Iranian deities. Their rulers established ruler cults in the manner of Hellenistic kings and often used Hellenistic royal epithets.

Problem: The first attempts to use standard-frequency single-phase AC were made in Hungary as far back as 1923, by the Hungarian Kalman Kando on the line between Budapest-Nyugati and Alag, using 16 kV at 50 Hz. The locomotives carried a four-pole rotating phase converter feeding a single traction motor of the polyphase induction type at 600 to 1,100 V. The number of poles on the 2,500 hp motor could be changed using slip rings to run at one of four synchronous speeds. The tests were a success so, from 1932 until the 1960s, trains on the Budapest-Hegyeshalom line (towards Vienna) regularly used the same system. A few decades after the Second World War, the 16 kV was changed to the Russian and later French 25 kV system.
What system was adopted in Hungary after WWII?
