Difficulty: MediumExtracting Supporting Details and Facts

An excerpt from an academic oral presentation delivered at a Latin American renewable energy conference states: "The Cerro Dominador solar thermal plant in the Atacama Desert utilizes a molten salt thermal storage system containing 56,000 metric tons of nitrate salts, enabling the facility to produce electricity continuously for 17.5 hours without direct sunlight. Although baseline engineering models projected an annual water consumption of 450,000 cubic meters for optical mirror washing, the deployment of specialized dry-cleaning robotic sweepers lowered this specific water requirement to 68,000 cubic meters per year."

Statement: According to the presentation, the implementation of robotic dry-cleaning sweepers lowered the annual water requirement for mirror cleaning to 68,000 cubic meters.

Answer: Answer

Answer

True. The presentation directly states that dry-cleaning robotic sweepers reduced mirror-washing water consumption to 68,000 cubic meters per year.
The factual claim accurately reflects the specific detail provided in the presentation transcript, which credits dry-cleaning robotic sweepers with reducing annual mirror-cleaning water consumption from 450,000 cubic meters to 68,000 cubic meters.

Step-by-Step Solution

1
Identify the target claim in the evaluation statement regarding the role and numerical impact of the robotic sweepers on water consumption.
The statement claims robotic sweepers lowered mirror-cleaning water demand to 68,000 cubic meters per year.
Clarifying the specific factual assertion is necessary to verify exact supporting details in the transcript.
2
Locate and extract the corresponding data points from the oral presentation transcript.
The transcript confirms that baseline models projected 450,000 cubic meters, but dry-cleaning robotic sweepers lowered this specific requirement to 68,000 cubic meters per year.
Extracting verbatim factual and quantitative metrics ensures precise alignment without misinterpreting adjacent figures.
3
Compare the statement directly with the extracted evidence to determine factual accuracy.
The statement matches the factual details and data presented in the transcript.
Concluding the truth value based strictly on transcript evidence satisfies the listening comprehension objective.
