Question

president carter tried to ease cold war tensions when he took office in 1977 by
proposing to build more nuclear weapons.
vowing to destroy all us nuclear weapons.
negotiating the salt i treaty.
working with the leader of the soviet union.

Explanation:

• Building more nuclear weapons would escalate, not ease, Cold War tensions, so the first option is incorrect.
• Carter never vowed to destroy all US nuclear weapons, making the second option wrong.
• The SALT I Treaty was negotiated by the Nixon administration, not Carter, so the third option is incorrect.
• Carter pursued détente by engaging with Soviet leadership to reduce Cold War tensions, which matches the fourth option.

Answer:

D. working with the leader of the Soviet Union.
