Question

Which of the following is not a pillar of the Nuclear Nonproliferation Treaty (1968):

Nonproliferation.
Reduction of nuclear weapons by 85-90%.
Right to peacefully use nuclear power.
Disarmament.

Answer 1

"Reduction of nuclear weapons by 85–90%."

The NPT's three pillars are nonproliferation, disarmament (general obligation to pursue negotiations leading to nuclear disarmament), and the right to peaceful uses of nuclear energy. It does not set a specific 85–90% reduction target.
