The true statement about Argentina and El Salvador in the second half of 20th century is that both were ruled by military juntas.

Explanation:

-In Argentina, six successful coups were carried out during the twentieth century, in 1930, 1943, 1955, 1962, 1966 and 1976. The first four established provisional dictatorships, while the last two established dictatorships of permanent type according to the model of bureaucratic-authoritarian state. The latter imposed a state terrorism, in which human rights were massively violated and there were about 30,000 disappearances.

In the 53 years that have elapsed since the first successful coup, in 1930, until the last civil-military dictatorship fell in 1983, there were six military regimes in power, these totaling 25 years in total. During this period, all government experiences democratically elected between Radicals and Justicialists were interrupted by coups d'état.

-The same situation occurred in El Salvador from 1931 to 1979, when the authoritarian governments of the military-oligarchic regime used a policy that combined political repression and limited reforms to stay in power.
