Africans were brought to Charles Town on the Middle Passage, first as "servants", then as slaves. Ethnic groups transported here included especially Wolof, Yoruba, Fulani, Igbo, Malinke, and other people of the Windward Coast. An estimated 40% of the total 400,000 Africans transported and sold as slaves into North America are estimated to have landed at Sullivan's Island, just off the port of Charles Town; it is described as a "hellish Ellis Island of sorts .... Today nothing commemorates that ugly fact but a simple bench, established by the author Toni Morrison using private funds."
What percentage of those sold as slaves in North America landed at Sullivan's Island?
A: 40%

The remainder was the world-ocean known as Panthalassa ("all the sea"). All the deep-ocean sediments laid down during the Triassic have disappeared through subduction of oceanic plates; thus, very little is known of the Triassic open ocean. The supercontinent Pangaea was rifting during the Triassicespecially late in the periodbut had not yet separated. The first nonmarine sediments in the rift that marks the initial break-up of Pangeawhich separated New Jersey from Moroccoare of Late Triassic age; in the U.S., these thick sediments comprise the Newark Supergroup. Because of the limited shoreline of one super-continental mass, Triassic marine deposits are globally relatively rare; despite their prominence in Western Europe, where the Triassic was first studied. In North America, for example, marine deposits are limited to a few exposures in the west. Thus Triassic stratigraphy is mostly based on organisms living in lagoons and hypersaline environments, such as Estheria crustaceans and terrestrial vertebrates.
What type of terrestrial animals are found from the Triassic period?
A: terrestrial vertebrates

In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region. He based his study on statistical correlation. That Sichuan is a seismically active area has been discussed for years prior to the quake, though few studies point to a specific date and time.
When was a Seismic Risk Analysis published?
A: In 2002
