Just as Massachusetts Was a Leading State in Common School

Just as Massachusetts was a leading state in common school reform in the 1800s, so was it an important state early in the contemporary reform period. Why?

A) Massachusetts achieved economic prosperity by attracting high-tech industry, in part due to its educational resources.
B) Just as Massachusetts had led the early nineteenth-century United States in industrial development, it led late twentieth-century America in post-industrial information technology.
C) The Massachusetts economy sank so low in the early 1980s that its leaders started a school reform movement to jump-start the state economy.
D) For both these reasons: Massachusetts achieved economic prosperity by attracting high-tech industry, in part due to its educational resources; and, just as it had led the early nineteenth-century United States in industrial development, Massachusetts led late twentieth-century America in post-industrial information technology.
