What type of barrier might provide a more flexible option for audience separation?

The choice of rope or tape as a barrier for audience separation is advantageous due to its flexibility and ease of deployment. Unlike permanent fencing or concrete walls, which are fixed and require significant effort and resources to move or adjust, rope or tape can be easily set up, taken down, or repositioned as needed. This adaptability allows event organizers to quickly change layouts or respond to crowd dynamics without the need for heavy equipment or extensive labor. Additionally, using rope or tape can create a visually open environment while still effectively guiding audience flows and designating specific areas, making it suitable for various types of events where audience interaction or movement is anticipated.
