Because Few Children Grow Up Learning to Speak the Lakota

Because few children grow up learning to speak the Lakota language, efforts have been made to preserve language samples and artifacts in tribal areas. One of the major efforts in use today is:

A) a participatory social media platform built by LiveAndTell.
B) replacing standard English with the Lakota language in local schools.
C) the translation of the Christian Bible into the Lakota language by the Summer Institute of Linguistics.
D) legislation making the Lakota language the official language in all tribal areas.
