Modernization and changing lifestyles can lead to:

The correct answer is: All of the above.

Modernization and changing lifestyles can lead to modifications in festival traditions, decreased participation among younger generations, and commercialization of festivals.

• Modifications in festival traditions can occur as people become more exposed to different cultures and ideas. For example, some traditional festivals have been adapted to include elements of other cultures, such as food, music, or dance.
• Decreased participation among younger generations can occur as people become more busy with work and other commitments. In addition, younger generations may not see the same value in traditional festivals as their elders.
• Commercialization of festivals can occur as businesses see an opportunity to make money from festivals. This can lead to an increase in the cost of attending festivals, as well as a change in the focus of festivals from cultural celebration to economic activity.

It is important to note that these are just some of the potential impacts of modernization and changing lifestyles on festivals. The specific impact will vary depending on the particular festival and the community in which it is held.
