Question: The USS Luiseno was named after the tribe of Native Americans with how many cultural/linguistic divisions?

full_context: Document 1: Comanche history: Forming a part of the Eastern Shoshone linguistic group in southeastern Wyoming who moved on to the buffalo Plains around AD 1500 (based on glottochronological estimations), proto-Comanche groups split off and moved south some time before AD 1700. The Shoshone migration to the Great Plains was apparently triggered by the Little Ice Age, which allowed bison herds to grow in population. It is not clear why the proto-Comanches broke away from the main Plains Shoshones and migrated south. That move may have been inspired as much by the desire for Spanish horses released by the Pueblo Revolt of 1680 as by pressures from other groups drawn to the Plains by the changing environment.

Document 10: Nushibi: Nushibi (Nu-shibi, Chinese 弩失畢) was a Chinese collective name for five tribes of the right (western) wing in the Western Turkic Kaganate, and members of "On oq" (Turkic ten arrows) confederation found in the literature about the Western Turkic Kaganate as "Ten arrows (ten tribes) Türks". The references to Nushibi appeared in Chinese sources in 651 and disappeared after 766. The Nushibi tribes occupied the lands of the Western Turkic Kaganate west of the river Ili.
