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. These efforts include:

A) a participatory social media platform built by LiveandTell.
B) replacing Standard English with the Lakota language in local schools.
C) translation of the Christian Bible into the Lakota language by the Summer Institute of Linguistics.
D) expanding tribal areas to include more speakers.
E) legislation making the Lakota language the official language in tribal areas.
