Problem: Background: The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its hieroglyphic script--the only known fully developed writing system of the pre-Columbian Americas--as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. This region consists of the northern lowlands encompassing the Yucatan Peninsula, and the highlands of the Sierra Madre, running from the Mexican state of Chiapas, across southern Guatemala and onwards into El Salvador, and the southern lowlands of the Pacific littoral plain. The Archaic period, prior to 2000 BC, saw the first developments in agriculture and the earliest villages.
Context: The Maya developed their first civilization in the Preclassic period. Scholars continue to discuss when this era of Maya civilization began. Maya occupation at Cuello (modern-day Belize) has been carbon dated to around 2600 BC. Settlements were established around 1800 BC in the Soconusco region of the Pacific coast, and the Maya were already cultivating the staple crops of maize, beans, squash, and chili pepper. This period was characterized by sedentary communities and the introduction of pottery and fired clay figurines.  During the Middle Preclassic Period, small villages began to grow to form cities. Nakbe in the Peten department of Guatemala is the earliest well-documented city in the Maya lowlands, where large structures have been dated to around 750 BC. The northern lowlands of Yucatan were widely settled by the Middle Preclassic. By approximately 400 BC, early Maya rulers were raising stelae. A developed script was already being used in Peten by the 3rd century BC. In the Late Preclassic Period, the enormous city of El Mirador grew to cover approximately 16 square kilometres (6.2 sq mi). Although not as large, Tikal was already a significant city by around 350 BC.  In the highlands, Kaminaljuyu emerged as a principal centre in the Late Preclassic. Takalik Abaj and Chocola were two of the most important cities on the Pacific coastal plain, and Komchen grew to become an important site in northern Yucatan. The Late Preclassic cultural florescence collapsed in the 1st century AD and many of the great Maya cities of the epoch were abandoned; the cause of this collapse is unknown.
Question: Is there anything else important about the preclassic period?
Answer: In the highlands, Kaminaljuyu emerged as a principal centre in the Late Preclassic.

Problem: Background: Hideto Matsumoto (Song Ben  Xiu Ren , Matsumoto Hideto, December 13, 1964 - May 2, 1998), better known by his stage name hide, was a Japanese musician, singer and songwriter. He is primarily known for his work as lead guitarist of the heavy metal band X Japan.
Context: hide joined X Japan (then called X) in February 1987, becoming the band's lead guitarist and occasional songwriter, going on to compose songs like "Celebration", "Joker" and the single "Scars". X released their first album Vanishing Vision, through drummer Yoshiki's own Extasy Records, on April 14, 1988 and toured extensively in support of the record. They would become one of the first Japanese acts to achieve mainstream success while on an independent label, and later widely credited as one of the pioneers of visual kei.  X 's major label debut album, Blue Blood, was released on April 21, 1989 and debuted at number six on the Oricon chart. Its success earned the band the "Grand Prix New Artist of the Year" award at the 4th annual Japan Gold Disc Awards in 1990. Their third album Jealousy was released on July 1, 1991 and debuted at number one, selling over 600,000 copies. It was later certified million by the RIAJ.  Shortly after the release of Art of Life, which also topped the Oricon, the members of X Japan took a break, to start solo projects. Around that time, the group also dropped most of its original visual kei aesthetics, except hide who would still perform in wildly colorful outfits and with his trademark red, later pink, hair. Dahlia, which would become the band's last album, was released on November 4, 1996 and once again, it reached the number one spot. In September 1997 it was announced that X Japan would disband, they performed their farewell show, aptly titled The Last Live, at the Tokyo Dome on December 31, 1997.
