Which of the following factors is a major boost to tourism?
Adequate publicity about natural scenery
Variation in mode of transportation
Higher dependency ratio of the population
Specialization in labour force
Correct answer is A
Tourism is significantly boosted by adequate publicity about natural scenery. This is because it attracts tourists who are interested in exploring and experiencing the beauty of nature. The other options such as higher dependency ratio of the population, specialization in labour force, and variation in mode of transportation do not directly boost tourism.
