Question

Alliances are: *

O Secret treaties between nations causing possible conflicts
O Secret treaties that benefitted all nations involved
O Secret Treaties that controlled empires
O Treaties among neighboring nations meant to advance technology

Answer 1

Treaties are a formal agreement typically among nations

Alliances can be treaties to support one another, economically, militarily or other

An alliance can be secret or public so the last option would make sense except that they don’t necessarily need to involve technology.
