Problem: Guam:

After his arrival in 1674, Captain Damian de Esplana ordered the arrest of rebels who attacked the population of certain towns. Hostilities eventually led to the destruction of villages such as Chochogo, Pepura, Tumon, Sidia-Aty, Sagua, Nagan and Ninca.:74–75 Starting in June 1676, the first Spanish Governor of Guam, Capt. Francisco de Irrisarri y Vinar controlled internal affairs more strictly than his predecessors in order to curb tensions. He also ordered the construction of schools, roads and other infrastructure.:75–76 Later, Capt. Jose de Quiroga arrived in 1680 and continued some of the development projects started by his predecessors. He also continued the search for the rebels who had assassinated Father San Vitores, resulting in campaigns against the rebels which were hiding out in some islands, eventually leading to the death of Matapang, Hurao and Aguarin.:77–78 Quiroga brought some natives from the northern islands to Guam, ordering the population to live in a few large villages.:78–79 These included Jinapsan, Umatac, Pago, Agat and Inarajan, where he built a number of churches.:79 By July 1695, Quiroga had completed the pacification process in Guam, Rota, Tinian and Aguigan.:85

Problem: 2008 Sichuan earthquake:

According to a study by the China Earthquake Administration (CEA), the earthquake occurred along the Longmenshan fault, a thrust structure along the border of the Indo-Australian Plate and Eurasian Plate. Seismic activities concentrated on its mid-fracture (known as Yingxiu-Beichuan fracture). The rupture lasted close to 120 sec, with the majority of energy released in the first 80 sec. Starting from Wenchuan, the rupture propagated at an average speed of 3.1 kilometers per second 49° toward north east, rupturing a total of about 300 km. Maximum displacement amounted to 9 meters. The focus was deeper than 10 km.

Where is the Longmenshan fault located?
---
A: along the border of the Indo-Australian Plate and Eurasian Plate

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.
