Which work is an example of the hospitality sector?

Correct answer: Providing guest service in a hotel

The direct answer is D: providing guest service in a hotel. The hospitality sector is the part of the service sector that welcomes, accommodates, feeds, and cares for guests. A hotel worker may receive visitors, arrange rooms, serve food, answer questions, or solve guest problems. These activities provide a service rather than extracting a natural resource or producing a farm product. Option A, farming, belongs mainly to agriculture, where crops or animals are produced. Option B, mining, removes minerals from the earth and belongs to an extractive industry. Option C, extracting raw material, is also an extractive activity, not hospitality. Option D is correct because hotel guest service directly involves welcoming and helping customers. A useful exam cue is: hotel, restaurant, travel stay, and guest care usually point to hospitality. Remember that hospitality is about serving people pleasantly and responsibly.
