Question

how did the U.S. role in the Nicaraguan civil war change in 1982

Answer 1

There are several ways in which the U.S. role in the Nicaraguan civil war changed  in 1982 but perhaps the greatest way was that it became more involved. 

Answer 2

The correct answer is A

In 1982, the U.S Congress passed the first Boland Amendment. This was the first of three U.S. legislative amendment made between 1982 and 1984.

The aim of this Amendment was to stop the U.S. government's assistance to the  Contras, the armed opposition to Nicaragua's communist government during the Nicaraguan Civil War.

It prohibited the training, supplying, or funding of the Contra rebels. The amendment applied to any agency or entity of the United States "involved in intelligence activities."
