QUES: The last opus number that Chopin himself used was 65, allocated to the Cello Sonata in G minor. He expressed a deathbed wish that all his unpublished manuscripts be destroyed. At the request of the composer's mother and sisters, however, his musical executor Julian Fontana selected 23 unpublished piano pieces and grouped them into eight further opus numbers (Opp. 6673), published in 1855. In 1857, 17 Polish songs that Chopin wrote at various stages of his life were collected and published as Op. 74, though their order within the opus did not reflect the order of composition.
How many unfinished pieces did Julian Fontana make into eight more opus numbers?

ANS: 23

QUES: Nevertheless, whether and to what degree any of these types of intermediaries have secondary liability is the subject of ongoing litigation. The decentralised structure of peer-to-peer networks, in particular, does not sit easily with existing laws on online intermediaries' liability. The BitTorrent protocol established an entirely decentralised network architecture in order to distribute large files effectively. Recent developments in peer-to-peer technology towards more complex network configurations are said to have been driven by a desire to avoid liability as intermediaries under existing laws.
What makes peer-to-peer networks different than other online providers?

ANS: decentralised structure

QUES: The Ming initiated sporadic armed intervention in Tibet during the 14th century, but did not garrison permanent troops there. At times the Tibetans also used armed resistance against Ming forays. The Wanli Emperor (r. 15721620) made attempts to reestablish Sino-Tibetan relations after the Mongol-Tibetan alliance initiated in 1578, which affected the foreign policy of the subsequent Qing dynasty (16441912) of China in their support for the Dalai Lama of the Gelug school. By the late 16th century, the Mongols were successful armed protectors of the Gelug Dalai Lama, after increasing their presence in the Amdo region. This culminated in Gushi Khan's (15821655) conquest of Tibet from 16371642 and the establishment of the Ganden Phodrang regime by the 5th Dalai Lama with his help.
Who were the armed protectors for the Gelug Dalai Lama?

ANS: the Mongols

QUES: As part of the housing and credit booms, the number of financial agreements called mortgage-backed securities (MBS) and collateralized debt obligations (CDO), which derived their value from mortgage payments and housing prices, greatly increased.

As housing prices declined, major global financial institutions that had borrowed and invested heavily in subprime MBS reported significant losses.
What are CDO as related to the housing and credit booms?

collateralized debt obligations
