Twenty miles east of San Jose, an environmental research team converted a previously barren scrubland into a biologically diverse preserve by planting a mix of indigenous flowering shrubs, drought-resistant grasses, and several small water features designed to simulate natural streams. Although the region receives minimal annual rainfall, the water features are sustained using a controlled greywater recycling system. Since its creation, the preserve has supported a consistent rise in local insect species, followed by an increase in birds and small mammals that rely on insects and seeds for food. Due to this measurable increase in biodiversity, the preserve has been used as a case study for restoring ecological balance in arid regions. The organization overseeing the preserve does not intend to charge admission, but expects to offset operational costs through academic research grants, private ecological foundations, and eco-tourism partnerships.
Which of the following statements is most strongly supported by the information above?
A. The ecological health of the preserve is primarily due to the presence of artificially maintained water features rather than native plants.
B. If the insect population in the preserve had not increased, the preserve would have failed to attract birds and mammals.
C. The preserve’s financial sustainability depends at least in part on sources other than charging public visitors.
D. Without the water recycling system, the preserve would have faced seasonal collapses in its biodiversity.
E. Local farmers who draw water from the same region are likely to oppose the preserve’s greywater usage.

The passage clearly says that the preserve doesn’t plan to charge admission, and instead plans to cover operational costs through research grants, eco-tourism partnerships, and private ecological foundations. So it directly supports the idea that the preserve’s financial sustainability depends on sources other than charging visitors.
That’s exactly what option C is saying — and it's the only option that is fully supported by the information in the passage.
Now the other options:
A is too strong — it claims the water features are primarily responsible, but the passage never makes that comparison. It mentions both native plants and water features without saying which one matters more.
B is a “what if” scenario. Yes, insects came first, then birds/mammals, but we can't assume that without the insect increase, birds/mammals wouldn't have come at all.
D says biodiversity would collapse without greywater. That’s extreme — the passage doesn’t go that far.
E brings in local farmers, but farmers aren’t even mentioned — totally out of scope.
So overall, C is the final answer.
