Because the evidence contradicts the sweeping claim, it is 'untenable.' 'Fungible' means interchangeable, 'quixotic' means impractically idealistic, and 'germane' means relevant.

With a limited, confounded sample, conclusions are 'tentative.' 'Jubilant' is an emotion, 'ubiquitous' means widespread, and 'doctrinaire' means dogmatically inflexible.

The goal is to reduce instability, so mitigate fits. Oscillate means to swing, exacerbate means worsen, and incubate refers to developing organisms or ideas.

The added nuance serves to complicate the narrative. Conflate means merge, vindicate means justify, and replicate means copy.

Pragmatic describes a practical, results-oriented approach, consistent with incremental, targeted measures; didactic, quixotic, and dogmatic imply instructive, impractically idealistic, and inflexibly doctrinaire attitudes, respectively.

Untenable means not defensible, aligning with scientists' rejection of the claim given fuller data; incipient means beginning, decorous means proper, and ubiquitous means widespread, none of which fit.

Integral means essential, fitting the described ecological importance. Marginal and incidental suggest unimportance, and capricious means unpredictable, which is irrelevant here.

Tempered means moderated, aligning with optimism balanced by caveats. Amplified would increase optimism, contradicted would negate it, and adorned suggests mere decoration.

Because hidden costs erased the apparent savings, those savings were illusory. 'Muted' means subdued, 'circular' describes a type of reasoning, and 'buoyant' describes cheerfulness or rising markets.

Interrogate' precisely conveys critically examining omissions. 'Decorate' and 'accelerate' are off-topic actions, and 'replicate' would repeat the narrative rather than question it.
