Transcript of an oral presentation on agricultural innovation in the Peruvian Andes:

"Good morning. Today, I want to discuss how Andean communities are reviving ancient agricultural terraces known as andenes to combat modern climate unpredictability. In the Colca Valley, rising temperatures and irregular rainfall have threatened traditional crop yields. In response, a collaborative project restored 120 hectares of pre-Inca stone terraces between 2021 and 2024. These structures regulate soil moisture by capturing runoff and retain solar heat during frigid nights, elevating ambient soil temperature by up to three degrees Celsius. As a direct outcome of this restoration, participating farmers recorded a forty percent increase in maize and native potato production over three consecutive harvest cycles. Furthermore, local agricultural cooperatives established a seed bank containing over fifty ancestral quinoa varieties to safeguard genetic diversity. While regional governmental funding initially subsidized thirty percent of construction materials, community communal labor associations, known locally as faenas, carried out all physical rehabilitation work without external machinery."

According to the presentation, what specific result was achieved by restoring the stone terraces in the Colca Valley?

  1. A
    A community seed bank was created as the primary overarching goal of the entire restoration project.
  2. Participating farmers recorded a forty percent increase in maize and native potato production over three harvest cycles.Answer
  3. C
    External industrial machinery was imported to replace traditional Andean faena labor associations.
  4. D
    Regional governmental agencies fully funded the project due to community reluctance to use ancient techniques.

Answer

Participating farmers recorded a forty percent increase in maize and native potato production over three consecutive harvest cycles.
The speaker explicitly presents the factual outcome that participating farmers recorded a forty percent increase in maize and native potato production over three consecutive harvest cycles directly following the rehabilitation of the terraces.

Step-by-Step Solution

1
Identify the specific factual detail requested by the prompt regarding the direct results of restoring the stone terraces.
The objective is focused on locating quantitative or qualitative agricultural outcomes attributed to the terrace restoration.
Supporting detail questions test the ability to extract explicit facts directly connected to a specific sub-topic in the presentation.
2
Scan the oral presentation transcript for the direct outcomes associated with the Colca Valley terrace restoration project.
The transcript explicitly states: 'As a direct outcome of this restoration, participating farmers recorded a forty percent increase in maize and native potato production over three consecutive harvest cycles.'
This establishes the factual ground truth directly from the speaker's statements.
3
Evaluate the answer choices against the extracted factual details while eliminating distractors based on common comprehension errors.
The choice citing a forty percent increase in maize and native potato production over three harvest cycles exactly matches the explicit supporting fact.
Other choices confuse secondary initiatives, misstate financing proportions, or misinterpret traditional cultural labor practices.
