I believe the answer is A but i could be wrong, during the Civil war it made it easier for them to speak and talk to each other during that time sending goods and messages across the united states.
Hope this helps.
Answer:
D; to prevent militarization there
Explanation:
The treaty sets aside Antarctica as a scientific preserve, establishes freedom of scientific investigation, and bans military activity on the continent. The treaty was the first arms control agreement established during the Cold War.
They are: to demilitarize Antarctica, to establish it as a zone free of nuclear tests and the disposal of radioactive waste, and to ensure that it is used for peaceful purposes only; to promote international scientific cooperation in Antarctica; to set aside disputes over territorial sovereignty.
That's the same question I had but I don't know the answer.
