QUES: In August 2007 Virgil Griffith, a Caltech computation and neural-systems graduate student, created a searchable database that linked changes made by anonymous Wikipedia editors to companies and organizations from which the changes were made. The database cross-referenced logs of Wikipedia edits with publicly available records pertaining to the internet IP addresses edits were made from. Griffith was motivated by the edits from the United States Congress, and wanted to see if others were similarly promoting themselves. The tool was designed to detect conflict of interest edits. Among his findings were that FBI computers were used to edit the FBI article in Wikipedia. Although the edits correlated with known FBI IP addresses, there was no proof that the changes actually came from a member or employee of the FBI, only that someone who had access to their network had edited the FBI article in Wikipedia. Wikipedia spokespersons received Griffith's "WikiScanner" positively, noting that it helped prevent conflicts of interest from influencing articles as well as increasing transparency and mitigating attempts to remove or distort relevant facts.
What was Griffith's tool designed to detect?

ANS: conflict of interest edits

QUES: Mu'awiyah introduced postal service, Abd al-Malik extended it throughout his empire, and Walid made full use of it. The Umayyad Caliph Abd al-Malik developed a regular postal service. Umar bin Abdul-Aziz developed it further by building caravanserais at stages along the Khurasan highway. Relays of horses were used for the conveyance of dispatches between the caliph and his agents and officials posted in the provinces. The main highways were divided into stages of 12 miles (19 km) each and each stage had horses, donkeys or camels ready to carry the post. Primarily the service met the needs of Government officials, but travellers and their important dispatches were also benefitted by the system. The postal carriages were also used for the swift transport of troops. They were able to carry fifty to a hundred men at a time. Under Governor Yusuf bin Umar, the postal department of Iraq cost 4,000,000 dirhams a year.
Who shrunk the reach of the postal service throughout his empire?

QUES: Sex was used as an important element in the content and marketing the paper from the start, which Lamb believed was the most important part of his readers' lives. The first topless Page 3 model appeared on 17 November 1970, German-born Stephanie Rahn; she was tagged as a "Birthday Suit Girl" to mark the first anniversary of the relaunched Sun. A topless Page 3 model gradually became a regular fixture, and with increasingly risqué poses. Both feminists and many cultural conservatives saw the pictures as pornographic and misogynistic. Lamb expressed some regret at introducing the feature, although denied it was sexist. A Conservative council in Sowerby Bridge, Yorkshire, was the first to ban the paper from its public library, shortly after Page 3 began, because of its excessive sexual content. This decision was reversed after a sustained campaign by the newspaper itself lasting 16 months, and the election of a Labour-led council in 1971.
What did Lamb employ as an important theme from the beginning of the paper?

ANS:
Sex
