In a large urban area, an initiative was launched to integrate interactive digital displays, such as touch-screen information kiosks and augmented reality experiences, in various public spaces. Following the implementation of this initiative, there was a noticeable increase in the number of visitors and the duration of their stay in these areas compared to last year. The initiative's leaders concluded that the interactive digital displays were key in attracting and retaining more visitors.

C. The urban area has seen an overall increase in tourism due to a city-wide marketing campaign promoting its cultural and entertainment attractions.
D. The digital displays, while popular, require frequent maintenance and updates to remain functional and engaging for visitors.
E. Periods of heightened visitor engagement coincided with the city’s customary Christmas events and celebrations in these areas.
