Difficulty: EasyComprehending Specific Details

Transcript from an audio report on renewable energy infrastructure in Spain:

"Welcome to Innovaciones Verdes. Today we explore the Gemasolar thermosolar facility located in Seville. Unlike standard photovoltaic installations that only produce electricity during daylight hours, Gemasolar uses a central tower surrounded by 2,650 reflective heliostat mirrors. These mirrors concentrate solar radiation to heat molten salt storage tanks up to 500 degrees Celsius. This stored thermal energy enables the facility to continue generating electricity for up to 15 consecutive hours without any sunlight, successfully supplying power to approximately 27,000 households annually."

According to the audio report, for how many consecutive hours can the facility generate electricity without sunlight?

  1. A
    Up to 500 consecutive hours
  2. Up to 15 consecutive hoursAnswer
  3. C
    Up to 2,650 consecutive hours
  4. D
    Up to 27,000 consecutive hours

Answer

The facility can generate electricity for up to 15 consecutive hours without sunlight.
The correct response reflects the exact duration stated by the speaker, who notes that the stored thermal energy allows the plant to produce electricity for up to 15 consecutive hours when sunlight is unavailable.

Step-by-Step Solution

1
Identify the target detail requested by the prompt.
The target detail is the number of consecutive hours the thermosolar plant can produce electricity in the absence of sunlight.
The question asks specifically about the duration of power generation without sunlight.
2
Locate the corresponding sentence in the audio transcript.
The transcript states: 'This stored thermal energy enables the facility to continue generating electricity for up to 15 consecutive hours without any sunlight...'
Direct textual matching verifies the quantitative figure cited by the narrator.
3
Distinguish the correct numerical detail from other statistics cited in the audio.
The number 15 corresponds to the hours without sunlight, whereas 500 refers to degrees Celsius, 2,650 refers to the number of mirrors, and 27,000 refers to households served.
Careful extraction prevents confusing distinct numeric values mentioned within the same report.
