Visiting friends, sports, and shopping are all examples of which type of travel?

The correct choice, pleasure travel, refers to travel undertaken primarily for enjoyment and leisure, rather than for work or obligations. This type of travel encompasses a wide range of activities, including social visits such as visiting friends, engaging in recreational activities like attending sports events, and enjoying personal time spent shopping. The key characteristic of pleasure travel is that it focuses on personal enjoyment and leisure experiences, allowing individuals to relax, explore new environments, and participate in various enjoyable activities.

Business travel generally involves trips taken for work-related purposes, such as attending conferences or meetings, which is distinct from the leisurely motivations behind pleasure travel. Adventure travel usually includes activities that are physically challenging or involve exploration in exotic locations, which does not align with the casual enjoyment represented by visiting friends and shopping. Service travel usually relates to volunteering or providing assistance and is not focused on personal leisure. Therefore, pleasure travel is the most accurate description of the activities listed in the question.
