How did the Ming select new leaders or government officials?

Samuel Gridley Howe (November 10, 1801 – January 9, 1876) was a nineteenth century United States physician, abolitionist, and an advocate of education for the blind. He organized and was the first director of the Perkins Institution.

In 1831 he returned to the United States. Through his friend Dr. John Dix Fisher, a Boston physician who had started a movement there as early as 1826 to establish a school for the blind, he had learned of a similar school founded in Paris by Valentin Haüy. A committee organized by Fisher proposed to Howe that he direct the establishment of a New England Asylum for the Blind at Boston. He took up the project with characteristic ardor, and set out at once for Europe to investigate the problem.

Your answer should be A.  I wish you the best of luck Buddy!
