Problem: Police:

Law enforcement, however, constitutes only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Many police forces suffer from police corruption to a greater or lesser degree. The police force is usually a public sector service, meaning they are paid through taxes.

Context and question: According to the Quran, God communicated with man and made his will known through signs and revelations. Prophets, or 'Messengers of God', received revelations and delivered them to humanity. The message has been identical and for all humankind. "Nothing is said to you that was not said to the messengers before you, that your lord has at his Command forgiveness as well as a most Grievous Penalty." The revelation does not come directly from God to the prophets. Angels acting as God's messengers deliver the divine revelation to them. This comes out in Quran 42:51, in which it is stated: "It is not for any mortal that God should speak to them, except by revelation, or from behind a veil, or by sending a messenger to reveal by his permission whatsoever He will."
Who intermediates between God and prophets?
Answer: Angels

QUES: Although its PlayStation predecessors had been very dominant against the competition and were hugely profitable for Sony, PlayStation 3 had an inauspicious start, and Sony chairman and CEO Sir Howard Stringer initially could not convince investors of a turnaround in its fortunes. The PS3 lacked the unique gameplay of the more affordable Wii which became that generation's most successful console in terms of units sold. Furthermore, PS3 had to compete directly with Xbox 360 which had a market head start, and as a result the platform no longer had exclusive titles that the PS2 enjoyed such as the Grand Theft Auto and Final Fantasy series (regarding cross-platform games, Xbox 360 versions were generally considered superior in 2006, although by 2008 the PS3 versions had reached parity or surpassed), and it took longer than expected for PS3 to enjoy strong sales and close the gap with Xbox 360. Sony also continued to lose money on each PS3 sold through 2010, although the redesigned "slim" PS3 has cut these losses since then.

In 2006, did most people prefer the Xbox 360 or PS3 versions of cross-platform games?
What is the answer?
ANS:
Xbox 360 versions
