Problem: Background: The Olmecs were the earliest known major civilization in Mexico following a progressive development in Soconusco. They lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco. It has been speculated that the Olmecs derive in part from neighboring Mokaya or Mixe-Zoque. The Olmecs flourished during Mesoamerica's formative period, dating roughly from as early as 1500 BCE to about 400 BCE. Pre-
Context: The beginnings of Olmec civilization have traditionally been placed between 1400 and 1200 BCE. Past finds of Olmec remains ritually deposited at El Manati shrine (near San Lorenzo) moved this back to "at least" 1600-1500 BCE. It seems that the Olmec had their roots in early farming cultures of Tabasco, which began between 5100 BCE and 4600 BCE. These shared the same basic food crops and technologies of the later Olmec civilization. What is today called Olmec first appeared fully within the city of San Lorenzo Tenochtitlan, where distinctive Olmec features occurred around 1400 BCE. The rise of civilization was assisted by the local ecology of well-watered alluvial soil, as well as by the transportation network provided by the Coatzacoalcos River basin. This environment may be compared to that of other ancient centers of civilization: the Nile, Indus, and Yellow River valleys, and Mesopotamia. This highly productive environment encouraged a densely concentrated population, which in turn triggered the rise of an elite class. The elite class created the demand for the production of the symbolic and sophisticated luxury artifacts that define Olmec culture. Many of these luxury artifacts were made from materials such as jade, obsidian, and magnetite, which came from distant locations and suggest that early Olmec elites had access to an extensive trading network in Mesoamerica. The source of the most valued jade was the Motagua River valley in eastern Guatemala, and Olmec obsidian has been traced to sources in the Guatemala highlands, such as El Chayal and San Martin Jilotepeque, or in Puebla, distances ranging from 200 to 400 km (120-250 miles) away, respectively. The state of Guerrero, and in particular its early Mezcala culture, seem to have played an important role in the early history of Olmec culture. Olmec-style artifacts tend to appear earlier in some parts of Guerrero than in the Veracruz-Tabasco area. In particular, the relevant objects from the Amuco-Abelino site in Guerrero reveal dates as early as 1530 BCE. The city of Teopantecuanitlan in Guerrero is also relevant in this regard.
Question: What were the artifacts
Answer: The source of the most valued jade was the Motagua River valley in eastern Guatemala,

Problem: Background: Williams was born in Nassau, The Bahamas, on November 12, 1874, to Frederick Williams Jr. and his wife Julia. At the age of 11, Bert permanently emigrated with his parents, moving to Florida. The family later moved to Riverside, California, where he graduated from Riverside High School. In 1893, while still a teenager, he joined different West Coast minstrel shows, including Martin and Selig's Mastodon Minstrels, where he first met his future professional partner, George Walker.
Context: The following month, Williams & Walker had their greatest success to date with Sons of Ham, a broad farce that was perhaps most notable for its lack of the extreme "darkie" stereotypes which were then common. One of the show's songs, "Miss Hannah from Savannah," even touched upon class divisions within the black community. The pair had already begun to transition away from racial minstrel conventions to a more human style of comedy. In 1901, they recorded 13 discs for the Victor Talking Machine Company. Some of these, such as "The Phrenologist Coon," were standard blackface material, but the financial lament "When It's All Going Out and Nothing Coming In" was race-blind, and became one of Williams' best-known songs. Another Williams composition, "Good Morning Carrie", was covered by many artists, becoming one of the biggest hits of 1901. These discs existed only in pressings of fewer than 1,000, and were not heard by very many listeners. Sons of Ham ran for two years. In September 1902, Williams & Walker debuted their next vehicle, In Dahomey, which was an even bigger hit. In 1903 the production, with music by Will Marion Cook and lyrics by Paul Laurence Dunbar moved to New York City, where it became the first black musical to open on Broadway. Part of the inspiration for the show was Williams' copy of a 1670 book, Africa, in which author John Ogilby traced the history of the continent's tribes and peoples. "With this volume, I could prove that every Pullman porter is the descendant of a king," said Williams. This was a landmark event, but seating inside the theater was segregated. One of the musical's songs, "I'm a Jonah Man," helped codify Williams' hard-luck persona and tales of woe. It helped to establish the character Williams played most frequently in his career: the slow-talking, deep-thinking victim of life's misfortunes. "Even if it rained soup," Williams later explained, "[my character] would be found with a fork in his hand and no spoon in sight." However, Williams and Walker were ebullient about their Broadway breakthrough, which came years after they had established themselves as profitable stage stars. Williams wrote, "We'd get near enough to hear the Broadway audiences applaud sometimes, but it was some one else they were applauding. I used to be tempted to beg for a $15 job in a chorus just for one week so as to be able to say I'd been on Broadway once." Walker recalled, "Some years ago we were doing a dance before an east side audience. They gave us a hand, and I called out to them, "Some day we'll do this dance on Broadway!" Then they gave us the laugh. Just the same we gave Broadway that same dance." In Dahomey then traveled to London, where it was enthusiastically received. A command performance was given at Buckingham Palace in June 1903. The show's British tour continued through June 1904. In May, Williams and Walker were both initiated into the Edinburgh Lodge of the Freemasons; the Scottish Masons did not racially discriminate as the United States chapters did, including the northern states.
