Matching Treaties and Their Years: CTBT, ABM, START-I, SORT

This question requires matching significant international treaties related to arms control and disarmament with the years they were concluded or signed. To answer this, we need to know the historical context and timelines of these specific agreements.

Let's examine each treaty listed and identify its associated year:

• Comprehensive Test-Ban Treaty (CTBT): The CTBT is a multilateral treaty that bans all nuclear explosions, for both civilian and military purposes, in all environments. It was adopted by the United Nations General Assembly in 1996.
• Anti-Ballistic Missile (ABM) Treaty: The ABM Treaty was a treaty between the United States and the Soviet Union on the limitation of anti-ballistic missile systems used in defending areas against ballistic missile-delivered nuclear weapons. It was signed in 1972.
• Strategic Arms Reduction Treaty - I (START-I): START I was a bilateral treaty between the United States and the Soviet Union on the reduction and limitation of strategic offensive arms. The treaty was signed in 1991.
• Strategic Offensive Reduction Treaty (SORT): SORT, also known as the Moscow Treaty, was a strategic arms reduction treaty between the United States and Russia. It was signed in 2002.

Based on this information, we can match the treaties from List I with the years from List II:

• (a) Comprehensive Test-Ban Treaty (CTBT) matches with (iv) 1996.
• (b) Anti-Ballistic Missile (ABM) Treaty matches with (iii) 1972.
• (c) Strategic Arms Reduction Treaty - I (START-I) matches with (ii) 1991.
• (d) Strategic Offensive Reduction Treaty (SORT) matches with (i) 2002.

Let's present these matches in a table for clarity:

Now, let's see which option corresponds to these matches:

• (a) - (iv)
• (b) - (iii)
• (c) - (ii)
• (d) - (i)

This combination (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i) represents the correct matching of the treaties with their respective years.

Additional Information on Arms Control Treaties

These treaties are examples of international efforts aimed at controlling the proliferation and development of weapons, particularly nuclear and strategic arms. Understanding the key arms control treaties and their timelines is important for studying international relations and security.

• The ABM Treaty was a cornerstone of strategic stability during the Cold War, limiting defensive systems to prevent an arms race in defense. The US withdrew from it in 2002.
• The START treaties (START I, START II, New START) aimed to reduce the number of deployed strategic offensive nuclear weapons. START I was crucial in the post-Cold War era.
• The CTBT is a global treaty against nuclear weapons testing, aiming to curb the qualitative development of nuclear weapons. While widely signed, it has not yet entered into force because some key countries have not ratified it.
• SORT was a simpler agreement compared to START, focusing on reducing deployed strategic warheads rather than delivery systems.

Knowing the historical context and significance of each treaty helps in remembering the specific years and understanding their impact on global security.
