Problem: Please answer a question about the following article about Han dynasty:
The Eastern Han, also known as the Later Han, formally began on 5 August 25, when Liu Xiu became Emperor Guangwu of Han. During the widespread rebellion against Wang Mang, the state of Goguryeo was free to raid Han's Korean commanderies; Han did not reaffirm its control over the region until AD 30. The Trung Sisters of Vietnam rebelled against Han in AD 40. Their rebellion was crushed by Han general Ma Yuan (d. AD 49) in a campaign from AD 4243. Wang Mang renewed hostilities against the Xiongnu, who were estranged from Han until their leader Bi (), a rival claimant to the throne against his cousin Punu (), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.
In what year did Ma Yuan die?
A: AD 49
Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:

Australia: The event was held in Canberra, Australian Capital Territory on April 24, and covered around 16 km of Canberra's central areas, from Reconciliation Place to Commonwealth Park. Upon its arrival in Canberra, the Olympic flame was presented by Chinese officials to local Aboriginal elder Agnes Shea, of the Ngunnawal people. She, in turn, offered them a message stick, as a gift of peace and welcome. Hundreds of pro-Tibet protesters and thousands of Chinese students reportedly attended.
