The correct answer is B. Poverty
The Democrat President Lyndon Johnson launched the Great Society program in order to fight against poverty, social inequality, and discrimination. It was launched in a period of economic growth, therefore, one of its main clauses consisted of a general tax cut that would benefit the more vulnerable economic sectors of society. It covered a vast series of social aspects, like civil rights, education, health, housing, rural development, among others, but the central link was the "war on poverty."
