Iran, Iraq and which countries first created OPEC?

Analyze the question: OPEC is the Organization of the Petroleum Exporting Countries. The question asks which countries joined Iran and Iraq as the founding members.

Concept: OPEC was formed in Baghdad, Iraq, in September 1960. It had five founding members:

1. Iran
2. Iraq
3. Kuwait
4. Saudi Arabia
5. Venezuela

Nigeria joined later, in 1971.

Solution: Since Iran and Iraq are already named, the remaining three founders are Kuwait, Saudi Arabia and Venezuela.

Checking the options:

• A. Kuwait, Saudi Arabia: Correct countries, but incomplete because it leaves out Venezuela. Together with Iran and Iraq this gives only four members, not the five founders.
• B. Venezuela, Dubai, Greece: Dubai is a city in the UAE, not a country, and Greece was never a member. Wrong.
• C. Venezuela, Saudi Arabia, Kuwait: These are the three remaining founders. Correct.
• D. Venezuela, Vienna: Vienna is a city, not a country. It is the location of OPEC's headquarters (moved there from Geneva in 1965). Wrong.

**Answer: C.

Exam tip: Remember the founders as "I-I-K-S-V": Iran, Iraq, Kuwait, Saudi Arabia, Venezuela. The year is 1960 and the founding city is Baghdad. If an option lists a city (Vienna, Dubai), eliminate it immediately, because the question asks for countries.
