A.I. Explanation:

Option 1: "Its use of renewable energy in urban areas"

Explanation: While the text mentions that eco-lodges use renewable energy sources, it does not specify that this is in urban areas. The focus is on eco-lodges and their environmental practices, not urban energy use.

Option 2: "The presence of eco-lodges and protected areas"

Explanation: This option accurately reflects the main idea of the text, which highlights Costa Rica's eco-lodges and protected areas as key factors in its eco-tourism appeal. The text states that these lodges minimize environmental impact and that over 25% of the country is protected, making it attractive for eco-tourists.

Option 3: "Having the largest number of hotels in Central America"

Explanation: The text does not mention the number of hotels in Central America, nor does it suggest that this is a factor in Costa Rica's eco-tourism. The focus is on eco-lodges and conservation efforts, not the quantity of hotels.

Option 4: "Its policy on unrestricted tourism development"

Explanation: This option contradicts the text, which emphasizes Costa Rica's commitment to environmental preservation and conservation rather than unrestricted tourism development. The text suggests a careful approach to tourism that supports eco-tourism.
