What new goverment role did Marjis grandfather accept? What did he now study? Why?

Because her grandfather had been an educated man, the Shah had made him Prime Minister. Her grandfather had begun to read Marx and to meet Bolshevik intellectuals. These Bolshevik’s had persuaded him of the political fraud of the new Persia and he had become a Communist, disgusted that “people are condemned to a bleak future by their social class.” Her mother then comes in and tells how her grandfather had been imprisoned for his political beliefs.
