Input: 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.

What is made by placing a plate of blade of copper, brass, or bronze into vat of fermenting wine for several weeks, then scraping off and drying the green powder?

Article: Originally alphabets were written entirely in majuscule letters, spaced between well-defined upper and lower bounds. When written quickly with a pen, these tended to turn into rounder and much simpler forms. It is from these that the first minuscule hands developed, the half-uncials and cursive minuscule, which no longer stayed bound between a pair of lines. These in turn formed the foundations for the Carolingian minuscule script, developed by Alcuin for use in the court of Charlemagne, which quickly spread across Europe. The advantage of the minuscule over majuscule was improved, faster readability.[citation needed]

Question: What is a common advantage of miniscule over majuscule handwriting?
Ans: faster readability

Here is a question about this article: Large numbers of Bolivian highland peasants retained indigenous language, culture, customs, and communal organization throughout the Spanish conquest and the post-independence period. They mobilized to resist various attempts at the dissolution of communal landholdings and used legal recognition of "empowered caciques" to further communal organization. Indigenous revolts took place frequently until 1953. While the National Revolutionary Movement government begun in 1952 discouraged self-identification as indigenous (reclassifying rural people as campesinos, or peasants), renewed ethnic and class militancy re-emerged in the Katarista movement beginning in the 1970s. Lowland indigenous peoples, mostly in the east, entered national politics through the 1990 March for Territory and Dignity organized by the CIDOB confederation. That march successfully pressured the national government to sign the ILO Convention 169 and to begin the still-ongoing process of recognizing and titling indigenous territories. The 1994 Law of Popular Participation granted "grassroots territorial organizations" that are recognized by the state certain rights to govern local areas.
What is the answer to this question: What did the highland peasants resist attempts at?
****
So... dissolution of communal landholdings

The problem: Answer a question about this article:
The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.
Which year brought the end to silver being in dimes and quarters?
****
