Problem: Hokkien:

There are many Hokkien speakers among overseas Chinese in Southeast Asia as well as in the United States. Many ethnic Han Chinese emigrants to the region were Hoklo from southern Fujian, and brought the language to what is now Burma (Myanmar), Indonesia (the former Dutch East Indies) and present day Malaysia and Singapore (formerly Malaya and the British Straits Settlements). Many of the Hokkien dialects of this region are highly similar to Taiwanese and Amoy. Hokkien is reportedly the native language of up to 98.5% of the Chinese Filipino in the Philippines, among which is known locally as Lan-nang or Lán-lâng-oē ("Our people’s language"). Hokkien speakers form the largest group of Chinese in Singapore, Malaysia and Indonesia.[citation needed]

Problem: Great power:

Of the five original great powers recognised at the Congress of Vienna, only France and the United Kingdom have maintained that status continuously to the present day, although France was defeated in the Franco-Prussian War and occupied during World War II. After the Congress of Vienna, the British Empire emerged as the pre-eminent power, due to its navy and the extent of its territories, which signalled the beginning of the Pax Britannica and of the Great Game between the UK and Russia. The balance of power between the Great Powers became a major influence in European politics, prompting Otto von Bismarck to say "All politics reduces itself to this formula: try to be one of three, as long as the world is governed by the unstable equilibrium of five great powers."

Balance of power of great powers was a major influence on what continents politics?

A: European


Problem: Green:

Verdigris is made by placing a plate or blade of copper, brass or bronze, slightly warmed, into a vat of fermenting wine, leaving it there for several weeks, and then scraping off and drying the green powder that forms on the metal. The process of making verdigris was described in ancient times by Pliny. It was used by the Romans in the murals of Pompeii, and in Celtic medieval manuscripts as early as the 5th century AD. It produced a blue-green which no other pigment could imitate, but it had drawbacks; it was unstable, it could not resist dampness, it did not mix well with other colors, it could ruin other colors with which it came into contact., and it was toxic. Leonardo da Vinci, in his treatise on painting, warned artists not to use it. It was widely used in miniature paintings in Europe and Persia in the 16th and 17th centuries. Its use largely ended in the late 19th century, when it was replaced by the safer and more stable chrome green. Viridian, also called chrome green, is a pigment made with chromium oxide dihydrate, was patented in 1859. It became popular with painters, since, unlike other synthetic greens, it was stable and not toxic. Vincent van Gogh used it, along with Prussian blue, to create a dark blue sky with a greenish tint in his painting Cafe terrace at night.

Where was chrome green popular in the 16th century?
