Final answer:
The answer to 'The 3 branches of tourism are inbound, outbound, and what?' is domestic, with domestic tourism being vital as it supports the local economy and is exemplified by California being a favored destination.
Option 1.) Domestic is correct.
Step-by-step explanation:
The three branches of tourism are inbound, outbound, and domestic. Inbound refers to visitors coming into a country, outbound denotes residents of a country traveling to another, and domestic means traveling within one’s own country.
Domestic tourism is quite significant as it contributes to the local economy without the complexities of international travel. For example, California is a popular destination for domestic tourists within the United States, offering diverse attractions such as beaches, theme parks, and natural wonders like Yosemite National Park. Conversely, international tourists often flock to locations such as New York, Florida, and California, drawn by a combination of entertainment, natural beauty, and historical significance.
