Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

The biggest difference between an eco-lodge and a green hotel is the setting in which you'll find them. Eco lodges tend to be more remote, located in relatively pristine natural environments such as beaches, jungles and mountains. Green hotels, on the other hand, are more often associated with cities and towns.

Eco lodges and green hotels both emphasize elements such as environmental responsibility and minimizing negative impact. The best ones offer renewable energy sources, recycling services, eco-friendly toiletries, energy efficient lighting, locally sourced food, organic linens and towels, non-toxic cleaning supplies, non-disposable dishes, water conservation methods and various other sustainability-focused initiatives.

But eco lodges tend to be more dependent on the natural environment than green hotels. They are also generally more active in nature and wildlife conservation, more focused on educating visitors about the flora and fauna of local ecosystems, and more deeply connected with the area's indigenous culture (whose influence is often incorporated into the lodge's decor and restaurant menu).

The best eco lodges also work to ensure positive relationships with the local people. They train and employ them at fair wages, take part in community development initiatives, offer activities that help visitors conserve and appreciate local customs, and contribute to the local economy. In this way, they reinforce the notion of ecotourism as a more sustainable long-term business model than altering or destroying habitats for quick financial gains.
