Problem: Please answer a question about the following article about Kathmandu:
The Bagmati River which flows through Kathmandu is considered a holy river both by Hindus and Buddhists, and many Hindu temples are located on the banks of this river. The importance of the Bagmati also lies in the fact that Hindus are cremated on its banks, and Kirants are buried in the hills by its side. According to the Nepali Hindu tradition, the dead body must be dipped three times into the Bagmati before cremation. The chief mourner (usually the first son) who lights the funeral pyre must take a holy riverwater bath immediately after cremation. Many relatives who join the funeral procession also take bath in the Bagmati River or sprinkle the holy water on their bodies at the end of cremation as the Bagmati is believed to purify people spiritually.
In a Hindu funeral, who is typically the main mourner?
A: first son
Problem: Please answer a question about the following article about Muammar Gaddafi:
Gaddafi briefly studied History at the University of Libya in Benghazi, before dropping out to join the military. Despite his police record, in 1963 he began training at the Royal Military Academy, Benghazi, alongside several like-minded friends from Misrata. The armed forces offered the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change. Under Idris, Libya's armed forces were trained by the British military; this angered Gaddafi, who viewed the British as imperialists, and accordingly he refused to learn English and was rude to the British officers, ultimately failing his exams. British trainers reported him for insubordination and abusive behaviour, stating their suspicion that he was involved in the assassination of the military academy's commander in 1963. Such reports were ignored and Gaddafi quickly progressed through the course.
What did Gaddafi regard his British instructors as?
A: imperialists
Problem: Please answer a question about the following article about Railway electrification system:
The London Underground in England is one of the few networks that uses a four-rail system. The additional rail carries the electrical return that, on third rail and overhead networks, is provided by the running rails. On the London Underground, a top-contact third rail is beside the track, energized at +420v DC, and a top-contact fourth rail is located centrally between the running rails at 210v DC, which combine to provide a traction voltage of 630v DC. London Underground is now upgrading its fourth rail system to 750v DC with a positive conductor rail energised to +500v DC and a negative conductor rail energised to -250v DC. However, many older sections in tunnels are still energised to 630v DC. The same system was used for Milan's earliest underground line, Milan Metro's line 1, whose more recent lines use an overhead catenary or a third rail.
What is the volatage surge of the third rail of London Underground system?
A: +420v DC
Problem: Please answer a question about the following article about Mosaic:
The most important early Islamic mosaic work is the decoration of the Umayyad Mosque in Damascus, then capital of the Arab Caliphate. The mosque was built between 706 and 715. The caliph obtained 200 skilled workers from the Byzantine Emperor to decorate the building. This is evidenced by the partly Byzantine style of the decoration. The mosaics of the inner courtyard depict Paradise with beautiful trees, flowers and small hill towns and villages in the background. The mosaics include no human figures, which makes them different from the otherwise similar contemporary Byzantine works. The biggest continuous section survives under the western arcade of the courtyard, called the "Barada Panel" after the river Barada. It is thought that the mosque used to have the largest gold mosaic in the world, at over 4 m2. In 1893 a fire damaged the mosque extensively, and many mosaics were lost, although some have been restored since.
What is the largest section of mosaic still present in the Umayyad Mosque?
A:
the "Barada Panel"
