PROBLEM: Passage: The Jenkins Orphanage was established in 1891 by the Rev. Daniel J. Jenkins in Charleston. The orphanage accepted donations of musical instruments and Rev. Jenkins hired local Charleston musicians and Avery Institute Graduates to tutor the boys in music. As a result, Charleston musicians became proficient on a variety of instruments and were able to read music expertly. These traits set Jenkins musicians apart and helped land some of them positions in big bands with Duke Ellington and Count Basie. William "Cat" Anderson, Jabbo Smith, and Freddie Green are but a few of the alumni from the Jenkins Orphanage band who became professional musicians in some of the best bands of the day. Orphanages around the country began to develop brass bands in the wake of the Jenkins Orphanage Band's success. At the Colored Waif's Home Brass Band in New Orleans, for example, a young trumpeter named Louis Armstrong first began to draw attention.

SOLUTION: What year was the Jenkins Orphanage closed?

PROBLEM: Passage: The "Neo-Eriksonian" identity status paradigm emerged in later years[when?], driven largely by the work of James Marcia. This paradigm focuses upon the twin concepts of exploration and commitment. The central idea is that any individual's sense of identity is determined in large part by the explorations and commitments that he or she makes regarding certain personal and social traits. It follows that the core of the research in this paradigm investigates the degrees to which a person has made certain explorations, and the degree to which he or she displays a commitment to those explorations.

SOLUTION:
What identity status emerged very early on?
