Complete the passage by filling in the blank with the word that best preserves the logical support and cause-effect relationships established in the text.
Answer:Given that the introduction of specific mycorrhizal fungi into the depleted soil consistently boosted nutrient absorption among native saplings, forest ecologists concluded that the fungal symbionts 【facilitated】 the recovery of degraded woodland ecosystems; indeed, the subsequent resurgence of canopy density directly stemmed from this enhanced root uptake.
Answer
The blank requires a verb meaning 'helped bring about' or 'accelerated' (such as 'facilitated' or 'catalyzed') to align with the positive causal relationship established by the nutrient uptake boost and the subsequent canopy resurgence.
The correct response must reflect cause-and-effect alignment. The sentence uses 'Given that' to establish a beneficial cause (boosted nutrient uptake) and follows with 'indeed' and 'directly stemmed from' to emphasize that the fungal symbionts actively assisted or triggered the ecosystem recovery. Therefore, words meaning 'facilitated', 'catalyzed', or 'promoted' complete the logical structure accurately.
