Ex Input:
At Maecenas' insistence (according to the tradition) Virgil spent the ensuing years (perhaps 3729 BC) on the long didactic hexameter poem called the Georgics (from Greek, "On Working the Earth") which he dedicated to Maecenas. The ostensible theme of the Georgics is instruction in the methods of running a farm. In handling this theme, Virgil follows in the didactic ("how to") tradition of the Greek poet Hesiod's Works and Days and several works of the later Hellenistic poets. The four books of the Georgics focus respectively on raising crops and trees (1 and 2), livestock and horses (3), and beekeeping and the qualities of bees (4). Well-known passages include the beloved Laus Italiae of Book 2, the prologue description of the temple in Book 3, and the description of the plague at the end of Book 3. Book 4 concludes with a long mythological narrative, in the form of an epyllion which describes vividly the discovery of beekeeping by Aristaeus and the story of Orpheus' journey to the underworld. Ancient scholars, such as Servius, conjectured that the Aristaeus episode replaced, at the emperor's request, a long section in praise of Virgil's friend, the poet Gallus, who was disgraced by Augustus, and who committed suicide in 26 BC.

Ex Output:
Which long didactic hexameter poem did Virgil work on for several years?

After World War II, two new competing formats came onto the market and gradually replaced the standard "78": the 33 13 rpm (often just referred to as the 33 rpm), and the 45 rpm (see above). The 33 13 rpm LP (for "long-play") format was developed by Columbia Records and marketed in June 1948. RCA Victor developed the 45 rpm format and marketed it in March 1949, each pursuing their own r&d in secret. Both types of new disc used narrower grooves, intended to be played with smaller stylustypically 0.001 inches (25 m) wide, compared to 0.003 inches (76 m) for a 78so the new records were sometimes called Microgroove. In the mid-1950s all record companies agreed to a common recording standard called RIAA equalization. Prior to the establishment of the standard each company used its own preferred standard, requiring discriminating listeners to use pre-amplifiers with multiple selectable equalization curves.

Ex Output:
What two formats replaced the 78?

One by one, additional large hotels were constructed along the boardwalk, including the Brighton, Chelsea, Shelburne, Ambassador, Ritz Carlton, Mayflower, Madison House, and the Breakers. The Quaker-owned Chalfonte House, opened in 1868, and Haddon House, opened in 1869, flanked North Carolina Avenue at the beach end. Their original wood-frame structures would be enlarged, and even moved closer to the beach, over the years. The modern Chalfonte Hotel, eight stories tall, opened in 1904. The modern Haddon Hall was built in stages and was completed in 1929, at eleven stories. By this time, they were under the same ownership and merged into the Chalfonte-Haddon Hall Hotel, becoming the city's largest hotel with nearly 1,000 rooms. By 1930, the Claridge, the city's last large hotel before the casinos, opened its doors. The 400-room Claridge was built by a partnership that included renowned Philadelphia contractor John McShain. At 24 stories, it would become known as the "Skyscraper By The Sea." The city became known as the "The World's Playground.

Ex Output:
What year did the Quaker-owned Chalfonte House open?
