Consider the following countries:

I. Austria II. Bulgaria III. Croatia IV. Serbia V. Sweden VI. North Macedonia

How many of the above are members of the North Atlantic Treaty Organization?

A. Only three

B. Only four

C. Only five

D. All the six

Answer: B

Explanation

Austria: NATO Member - NO Austria has maintained a policy of neutrality since 1955 and is not a member of NATO. Austria joined the EU in 1995 but has consistently remained outside military alliances.

Bulgaria: NATO Member - YES Bulgaria joined NATO on March 29, 2004, as part of the largest expansion in NATO's history, along with six other countries including Romania, Slovakia, Slovenia, Estonia, Latvia, and Lithuania.

Croatia: NATO Member - YES Croatia became a NATO member on April 1, 2009, along with Albania. This was NATO's fourth round of expansion after the end of the Cold War.

Serbia: NATO Member - NO Serbia is not a NATO member and maintains a policy of military neutrality. Serbia has a Partnership for Peace agreement with NATO but has not pursued full membership, partly due to historical tensions stemming from the 1999 NATO bombing of Yugoslavia.

Sweden: NATO Member - YES Sweden officially became NATO's 32nd member on March 7, 2024, ending decades of neutrality. This decision was accelerated following Russia's invasion of Ukraine in 2022.

North Macedonia: NATO Member - YES North Macedonia became NATO's 30th member on March 27, 2020. The country's NATO bid was delayed for years due to the naming dispute with Greece, which was resolved in 2018 with the Prespa Agreement.

Summary: NATO Members: Bulgaria, Croatia, Sweden, North Macedonia (4 countries) Non-NATO Members: Austria, Serbia (2 countries)

Therefore, only four of the listed countries are NATO members.

QUESTION 8

EasyInternational RelationsPrelims 2025

India is one of the founding members of the International North-South Transport Corridor (INSTC), a multimodal transportation corridor, which will connect

A. India to Central Asia to Europe via Iran

B. India to Central Asia via China

C. India to South-East Asia through Bangladesh and Myanmar

D. India to Europe through Azerbaijan

Answer: A

Explanation

  • A. India to Central Asia to Europe via Iran: This is correct. The International North-South Transport Corridor (INSTC) is a multi-modal network (ship, rail, and road) that connects India (starting from Mumbai) to Iran (Bandar Abbas), then through Iran to Azerbaijan, Russia, and further to Central Asia and Europe. The main route is India–Iran–Azerbaijan–Russia–Europe, facilitating trade between India, Central Asia, and Europe.

  • B. India to Central Asia via China: Incorrect. The INSTC does not pass through China. It is specifically designed as an alternative to routes passing through China and focuses on Iran, Azerbaijan, and Russia.

  • C. India to South-East Asia through Bangladesh and Myanmar: Incorrect. This describes the India-Myanmar-Thailand Trilateral Highway or other regional connectivity projects, not the INSTC.

  • D. India to Europe through Azerbaijan: Incorrect. While Azerbaijan is a part of the INSTC route, the corridor's main feature is the connection via Iran, not directly from India to Europe through Azerbaijan alone. The key is the multimodal link via Iran.

Therefore, option A is the most accurate answer as it correctly describes the INSTC's route and purpose.
