On August 5, 2008, SCA and Bertelsmann announced that Sony had agreed to acquire Bertelsmann's 50% stake in Sony BMG. Sony completed its acquisition of Bertelsmann's 50% stake in the companies' joint venture on October 1, 2008. The company, once again named Sony Music Entertainment Inc., became a wholly owned subsidiary of Sony Corporation through its US subsidiary SCA. The last few albums to feature a Sony BMG logo were Thriller 25 by Michael Jackson, I Am... Sasha Fierce by Beyonce, Keeps Gettin' Better: A Decade of Hits by Christina Aguilera, and Safe Trip Home by Dido. A temporary logo was unveiled beginning December 1, 2008. The present logo was unveiled in March 2009.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was Sony's new logo revealed to the public?
Ah, so.. 2009

Polish composers of the following generation included virtuosi such as Moritz Moszkowski, but, in the opinion of J. Barrie Jones, his "one worthy successor" among his compatriots was Karol Szymanowski (18821937). Edvard Grieg, Antonin Dvorak, Isaac Albeniz, Pyotr Ilyich Tchaikovsky and Sergei Rachmaninoff, among others, are regarded by critics as having been influenced by Chopin's use of national modes and idioms. Alexander Scriabin was devoted to the music of Chopin, and his early published works include nineteen mazurkas, as well as numerous etudes and preludes; his teacher Nikolai Zverev drilled him in Chopin's works to improve his virtuosity as a performer. In the 20th century, composers who paid homage to (or in some cases parodied) the music of Chopin included George Crumb, Bohuslav Martinu, Darius Milhaud, Igor Stravinsky and Heitor Villa-Lobos.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was Alexander Scriabin's teacher?
Ah, so.. Nikolai Zverev

In 1972, in a mosque in the city of Sana'a, Yemen, manuscripts were discovered that were later proved to be the most ancient Quranic text known to exist at the time. The Sana'a manuscripts contain palimpsests, a manuscript page from which the text has been washed off to make the parchment reusable againa practice which was common in ancient times due to scarcity of writing material. However, the faint washed-off underlying text (scriptio inferior) is still barely visible and believed to be "pre-Uthmanic" Quranic content, while the text written on top (scriptio superior) is believed to belong to Uthmanic time. Studies using radiocarbon dating indicate that the parchments are dated to the period before 671 AD with a 99 percent probability.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In which city was evidence of pre-Uthmanic Quranic writing discovered in 1927?
Ah, so..
unanswerable
