I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Flights are available from most countries, though direct flights are limited to mainly Thai and other ASEAN airlines. According to Eleven magazine, "In the past, there were only 15 international airlines and increasing numbers of airlines have began launching direct flights from Japan, Qatar, Taiwan, South Korea, Germany and Singapore." Expansions were expected in September 2013, but yet again are mainly Thai and other Asian-based airlines according to Eleven Media Group's Eleven, "Thailand-based Nok Air and Business Airlines and Singapore-based Tiger Airline"."?
A:
Which of the following is not a country: Thailand, South Korea, or Tiger?
