Which of these is a factor that contributes to cultural change over time
cultural attribute
cultural predjudice
blending cultures
traditional cultures

Blending cultures is a factor that eventually translates to cultural change.

Explanation:

In the day-to-day activities, people encounter others who have different cultural beliefs, traditions and customs. As they interact with other cultural aspects, although there might arise conflicts but eventually there is borrowing and complete culture change.

Cultural blending therefore will lead to cultural change if we are to consider the changes that occur, beliefs, customs and traditions are copied by one community or both.

The ideas copied from the other community will lead to culture change as they will be absorbed to completely become part of their culture and it will no longer be what it used to be.

i believe that the answer to the question provided above is that the role of campaign committees is to act as a bridge between state and local campaigns.
