Problem: Sony Music Entertainment:

In 1970, CBS Records revived the Embassy Records imprint in UK and Europe, which had been defunct since CBS had taken control of Embassy's parent company, Oriole, in 1964. The purpose of the revived Embassy imprint was to release budget reissues of albums that had originally been released in the United States on Columbia Records (or its subsidiaries). Many albums, by artists as diverse as Andy Williams, Johnny Cash, Barbra Streisand, the Byrds, Tammy Wynette, Laura Nyro and Sly & the Family Stone were issued on Embassy, before the label was once again discontinued in 1980.

CBS had taken control of Oriole's parent company in what year?

Problem: MP3:

An additional extension to MPEG-2 is named MPEG-2.5 audio, as MPEG-3 already had a different meaning. This extension was developed at Fraunhofer IIS, the registered MP3 patent holders. Like MPEG-2, MPEG-2.5 adds new sampling rates exactly half of that previously possible with MPEG-2. It thus widens the scope of MP3 to include human speech and other applications requiring only 25% of the frequency reproduction possible with MPEG-1. While not an ISO recognized standard, MPEG-2.5 is widely supported by both inexpensive and brand name digital audio players as well as computer software based MP3 encoders and decoders. A sample rate comparison between MPEG-1, 2 and 2.5 is given further down. MPEG-2.5 was not developed by MPEG and was never approved as an international standard. MPEG-2.5 is thus an unofficial or proprietary extension to the MP3 format.

As MPEG-2.5 is unofficial, it is considered what kind of extension to the MP3 format?

A: proprietary


Problem: Group (mathematics):

This set inherits a group operation (sometimes called coset multiplication, or coset addition) from the original group G: (gN) • (hN) = (gh)N for all g and h in G. This definition is motivated by the idea (itself an instance of general structural considerations outlined above) that the map G → G / N that associates to any element g its coset gN be a group homomorphism, or by general abstract considerations called universal properties. The coset eN = N serves as the identity in this group, and the inverse of gN in the quotient group is (gN)−1 = (g−1)N.e[›]

What group operation is taken by the original group from the set?

A: unanswerable


Problem: Religion in ancient Rome:

Public religion took place within a sacred precinct that had been marked out ritually by an augur. The original meaning of the Latin word templum was this sacred space, and only later referred to a building. Rome itself was an intrinsically sacred space; its ancient boundary (pomerium) had been marked by Romulus himself with oxen and plough; what lay within was the earthly home and protectorate of the gods of the state. In Rome, the central references for the establishment of an augural templum appear to have been the Via Sacra (Sacred Way) and the pomerium. Magistrates sought divine opinion of proposed official acts through an augur, who read the divine will through observations made within the templum before, during and after an act of sacrifice. Divine disapproval could arise through unfit sacrifice, errant rites (vitium) or an unacceptable plan of action. If an unfavourable sign was given, the magistrate could repeat the sacrifice until favourable signs were seen, consult with his augural colleagues, or abandon the project. Magistrates could use their right of augury (ius augurum) to adjourn and overturn the process of law, but were obliged to base their decision on the augur's observations and advice. For Cicero, himself an augur, this made the augur the most powerful authority in the Late Republic. By his time (mid 1st century BC) augury was supervised by the college of pontifices, whose powers were increasingly woven into the magistracies of the cursus honorum.

Who designated the first boundary of Rome?

A:
Romulus
