Article: Families throughout Han China made ritual sacrifices of animals and food to deities, spirits, and ancestors at temples and shrines, in the belief that these items could be utilized by those in the spiritual realm. It was thought that each person had a two-part soul: the spirit-soul (hun 魂) which journeyed to the afterlife paradise of immortals (xian), and the body-soul (po 魄) which remained in its grave or tomb on earth and was only reunited with the spirit-soul through a ritual ceremony. These tombs were commonly adorned with uniquely decorated hollow clay tiles that function also as a doorjamb to the tomb. Otherwise known as tomb tiles, these artifacts feature holes in the top and bottom of the tile allowing it to pivot. Similar tiles have been found in the Chengdu area of Sichuan province in south-central China.

Question: What type of decoration was often seen in tombs?
Ans: hollow clay tiles


Article: Whether there are measurable changes in the sea level relative to the islands of Tuvalu is a contentious issue. There were problems associated with the pre-1993 sea level records from Funafuti which resulted in improvements in the recording technology to provide more reliable data for analysis. The degree of uncertainty as to estimates of sea level change relative to the islands of Tuvalu was reflected in the conclusions made in 2002 from the available data. The 2011 report of the Pacific Climate Change Science Program published by the Australian Government, concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."

Question: What device was used to produce the measurements of sea level change on Tuvalu?
Ans: satellite


Article: The Hoddle Grid (dimensions of 1 by 1⁄2 mile (1.61 by 0.80 km)) forms the centre of Melbourne's central business district. The grid's southern edge fronts onto the Yarra River. Office, commercial and public developments in the adjoining districts of Southbank and Docklands have made these redeveloped areas into extensions of the CBD in all but name. The city centre has a reputation for its historic and prominent lanes and arcades (most notably Block Place and Royal Arcade) which contain a variety of shops and cafés and are a byproduct of the city's layout.

Question: Which edge of the Hoddle Grid fronts onto the Yarra River?
Ans: southern


Article: Albrecht von Roon, the Prussian Minister of War from 1859 to 1873, put into effect a series of reforms of the Prussian military system in the 1860s. Among these were two major reforms that substantially increased the military power of Germany. The first was a reorganization of the army that integrated the regular army and the Landwehr reserves. The second was the provision for the conscription of every male Prussian of military age in the event of mobilization. Thus, despite the population of France being greater than the population of all of the German states that participated in the war, the Germans mobilized more soldiers for battle.

Question: What was the time span that von Roon acted as minister?
Ans:
1859 to 1873
