Arelatively new domestic issue that has emerged in the united states since the 1980s is a) hyperinflation. b) racially-inspired riots. c) mass demonstrations to protest war. d) terrorism at home against u. s. citizens and institutions.

The correct answer is D)Terrorism at home against U.S. citizens and institutions.

Letter A cannot be the correct answer because hyperinflation was not part of the 1980's or 1990's. America, for the most part, had great economic success during these two decades.

Letter B and C cannot be corrected because there were racial riots and protests against war throughout the 1960's.

This shows that the only correct answer can be D.
