I want to know the answer to the following question:
What is the largest country that was included among the seven promoted countries?
All the background I'm provided with is that "This includes all developed countries, such as those in North America, Western Europe, Oceania, and Eastern Asia, as well as some developing countries in Eastern Europe, Central and South America, Southeast Asia, the Caribbean, and the oil-rich Arabian Peninsula.". Is that enough to answer the question?
