E.5 Synthesis, Evaluation, and Skills

The scenario describes a loop where an output (increased visitor numbers) generates revenue that funds more marketing (a new input), which draws even more visitors. The arrows circle back to an earlier stage in the system, confirming this is a genuine feedback loop, not just linear cause-and-effect.

Because each cycle reinforces and amplifies the original change (more visitors → more investment → more visitors still), this is positive (reinforcing) feedback. Positive feedback does not mean 'beneficial'; it means the system is moving further from equilibrium with each cycle.

Unchecked positive feedback in a tourism system is closely associated with Butler's Model: the destination accelerates through the development and consolidation stages, but without carrying-capacity management, it overshoots its sustainable limit and enters stagnation or decline.

The correct answer identifies this as a positive feedback loop that amplifies growth and risks exceeding carrying capacity. The other options either misclassify the loop type or incorrectly describe it as self-correcting.

The question asks both to classify the feedback loop type (positive or negative) and to predict its long-term outcome if left unmanaged.

Options A and C both describe negative feedback (a self-limiting or reversing loop). The scenario shows reinforcement, not correction — more investment leads to more visitors, not fewer — so both are eliminated.

Option D claims the positive loop is 'self-correcting because rising costs limit arrivals.' Rising costs may eventually constrain demand, but this would be a separate negative feedback mechanism triggered later; it is not an inherent feature of the reinforcing loop described in the scenario.

Option B correctly classifies the loop as positive (reinforcing) and accurately predicts its risk: unchecked growth overshoots the resort's carrying capacity, consistent with the stagnation stage of Butler's Model.

Representativeness must be assessed across three dimensions: sampling strategy (how respondents were selected), spatial coverage (where in the study area data was collected), and temporal coverage (when data was collected). A weakness in any one dimension limits generalizability.

Spatial coverage is weak: only one access point was used, missing visitors who approach from other trails. Temporal coverage is weak: one Sunday morning in August captures peak-season weekend patterns only, excluding weekday visitors, off-season users, and different times of day. Sample size (25) adds further random error but is not the sole or even primary problem.

A more representative sample would use stratified or systematic sampling across multiple access points, on different days of the week and across different seasons. Raising sample size alone without addressing location and timing would still produce a biased picture of all visitors.

The correct answer identifies both spatial and temporal coverage as the core weaknesses, correctly naming what makes the sample unrepresentative — not simply its size or its sampling technique label.

The question asks which evaluation of the sample's representativeness is most accurate, requiring an understanding of why a sample might or might not reflect the wider visitor population.

Option A argues the trailhead captures all visitor types. In reality, visitors arriving by other routes, visiting at different times, or not passing through that point would be entirely missed, making this claim indefensible.

Option B states that increasing sample size at the same location and time would fix representativeness. A larger convenience sample drawn from only one location on one Sunday morning would still systematically over-represent that specific visitor profile — size does not cure spatial or temporal bias.

Option D focuses entirely on the choice between systematic and stratified methods without addressing where and when data was collected. Changing the selection method at the same single location and time would not resolve spatial or temporal under-coverage.

Option C correctly identifies both the spatial limitation (one access point) and the temporal limitation (one Sunday morning in peak season) as the central weaknesses, making it the most comprehensive and accurate evaluation.
