[单项选择]The Aleuts, residing on several islands of the Aleutian Chain, the Pribilof islands, and the Alaskan Peninsula, have possessed a written language since 1825, when the Russian missionary Ivan Veniaminov selected appropriate characters of the Cyrillic alphabet to represent Aleut speech sounds, recorded the main body of Aleut vocabulary, and formulated grammatical rules.

A. the Aleuts’ loyalty to their language and American failure to understand it
