Problem: Please answer a question about the following article about Alloy:
The term pewter covers a variety of alloys consisting primarily of tin. As a pure metal, tin was much too soft to be used for any practical purpose. However, in the Bronze age, tin was a rare metal and, in many parts of Europe and the Mediterranean, was often valued higher than gold. To make jewelry, forks and spoons, or other objects from tin, it was usually alloyed with other metals to increase its strength and hardness. These metals were typically lead, antimony, bismuth or copper. These solutes sometimes were added individually in varying amounts, or added together, making a wide variety of things, ranging from practical items, like dishes, surgical tools, candlesticks or funnels, to decorative items such as ear rings and hair clips.
During the bronze age, which metal was valued higher than gold in Europe and the Mediterranean?
A: tin
Problem: Please answer a question about the following article about Armenia:
Gorbachev's inability to alleviate any of Armenia's problems created disillusionment among the Armenians and fed a growing hunger for independence. In May 1990, the New Armenian Army (NAA) was established, serving as a defence force separate from the Soviet Red Army. Clashes soon broke out between the NAA and Soviet Internal Security Forces (MVD) troops based in Yerevan when Armenians decided to commemorate the establishment of the 1918 First Republic of Armenia. The violence resulted in the deaths of five Armenians killed in a shootout with the MVD at the railway station. Witnesses there claimed that the MVD used excessive force and that they had instigated the fighting.
Who started the fight between the MVD and the NAA in 1918?
A: the MVD
Problem: Please answer a question about the following article about Buckingham Palace:
Possibly the first house erected within the site was that of a Sir William Blake, around 1624. The next owner was Lord Goring, who from 1633 extended Blake's house and developed much of today's garden, then known as Goring Great Garden. He did not, however, obtain the freehold interest in the mulberry garden. Unbeknown to Goring, in 1640 the document "failed to pass the Great Seal before King Charles I fled London, which it needed to do for legal execution". It was this critical omission that helped the British royal family regain the freehold under King George III.

A: Goring Great Garden
