Official Solution:
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, both visitor numbers and average visit duration in these public spaces increased noticeably compared with the same calendar period of the previous year. The initiative's leaders concluded that the interactive digital displays were key in attracting and retaining more visitors.
Which of the following, if true, most seriously undermines the initiative leaders’ conclusion?
A. Surveys reveal that the primary attraction for visitors to these urban areas remains the variety of shopping and dining options available, rather than the interactive digital displays.
B. The interactive digital displays are often located near popular attractions and dining areas, potentially influencing visitor traffic patterns in their vicinity.
C. Comparable public spaces in the same city where no digital displays were installed experienced approximately the same percentage increases in visitor numbers and average visit duration over the same period.
D. The digital displays, while popular, require frequent maintenance and updates to remain functional and engaging for visitors.
E. In both comparison periods, visitor numbers and average visit duration were highest during the city’s annual Christmas celebrations.
The leaders conclude that the interactive digital displays were key in increasing visitor numbers and average visit duration. Their evidence is that both measures increased after the displays were installed. To weaken this argument, we need to challenge the attribution of those increases to the displays, not deny that the increases occurred.
C. Correct. Comparable public spaces without digital displays experienced approximately the same percentage increases in visitor numbers and average visit duration over the same period. Thus, similar improvements occurred where the proposed cause—the installation of displays was absent. This suggests that broader influences could account for the improvements attributed to the initiative. It does not prove that the displays had no effect, but it substantially weakens the claim that they were key to producing the increases.
A. Incorrect. The primary reason people visit an area is not necessarily the reason visits increased. Shopping and dining could remain the main attractions while the displays encourage additional visits or longer stays. Moreover, “remains” does not establish that attendance associated with shopping and dining stayed constant. This choice identifies visitors’ main attraction but does not establish what caused the year-over-year increases.
B. Incorrect. Proximity to popular attractions may help explain visitor traffic patterns, but it does not establish why visitor numbers and average visit duration increased compared with the previous year. The choice does not indicate that those attractions changed during the comparison period or provide evidence that similar increases occurred without the displays. The location of the displays is therefore compatible with the leaders’ conclusion.
D. Incorrect. Frequent maintenance and updates are operational requirements, not evidence that the displays failed to attract visitors or encourage longer stays. The choice does not say that maintenance problems prevented visitors from using the displays. The displays could require substantial upkeep and still have the effects claimed by the leaders.
E. Incorrect. Christmas celebrations can affect both visitor numbers and visit duration. However, this choice describes seasonal peaks in both comparison periods; it does not establish that the celebrations account for the difference between the two years. Annual events need not have identical effects every year, but the choice provides no evidence that their effects were greater in the year after the displays were installed.
