Question

what was one effect of u.s. nuclear testing during the cold war?
a. soviet satellite nations began to protest repressive laws.
b. soviet political reforms led to a more open society.
c. trade negotiations improved between the united states and the soviet union
d. tensions between the united states and the soviet union increased

Explanation:

U.S. nuclear testing during the Cold War escalated the nuclear arms race, as the Soviet Union responded with its own tests and military buildup, directly increasing mutual distrust and tensions between the two superpowers. The other options are unrelated: satellite nation protests stemmed from Soviet internal control, Soviet political reforms were a later internal development, and trade negotiations did not improve due to nuclear testing.

Answer:

D. Tensions between the United States and the Soviet Union increased
