Input: Article: The Han dynasty inherited the ban liang coin type from the Qin. In the beginning of the Han, Emperor Gaozu closed the government mint in favor of private minting of coins. This decision was reversed in 186 BC by his widow Grand Empress Dowager Lu Zhi (d. 180 BC), who abolished private minting. In 182 BC, Lu Zhi issued a bronze coin that was much lighter in weight than previous coins. This caused widespread inflation that was not reduced until 175 BC when Emperor Wen allowed private minters to manufacture coins that were precisely 2.6 g (0.09 oz) in weight.

Now answer this question: In what year were private manufactures allowed to create coins that were exactly 2.6g in mass?

Output: 175 BC

Input: Article: Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.

Now answer this question: What happened to President Bonaparte in 1852?

Output: declared Emperor Napoleon III
