Read the following passage about resource management in Chile:

"In the hyper-arid communities of northern Chile's Atacama Desert, water is a constant luxury. However, in coastal villages like Chungungo, a simple yet innovative technology has quietly transformed daily life: the *atrapanieblas*, or fog catchers. These large mesh nets capture moisture from the dense coastal fog (*camanchaca*) that rolls over the cliffs, channeling it into pipes to provide clean water for agriculture and domestic use. While some industrial critics dismiss fog catching as an inefficient, small-scale alternative that cannot compete with modern desalination plants, supporters argue it represents a model of low-cost, decentralized sustainability. In a region where large-scale government infrastructure projects are routinely stalled by bureaucracy and fiscal deficits, the *atrapanieblas* offer immediate relief. Rather than waiting for top-down assistance, these communities have taken resource management into their own hands, demonstrating that adaptation to climate change does not always require high-tech, multi-million dollar investments, but rather a deep alignment with local geography and community-driven action."

Which of the following best describes the author's primary purpose in the passage?

  1. To champion the self-reliance of local communities and highlight the efficacy of low-cost, sustainable alternatives to centralized infrastructure.Answer
  2. B
    To detail the technical and physical mechanisms behind how the camanchaca fog condenses into drinkable water.
  3. C
    To lobby the Chilean government to immediately replace all urban desalination plants with fog-catching mesh nets.
  4. D
    To prove that decentralized resource projects are more economically profitable than industrial utilities.

Answer

To champion the self-reliance of local communities and highlight the efficacy of low-cost, sustainable alternatives to centralized infrastructure.
The correct option is the one stating that the purpose is to champion local self-reliance and highlight sustainable, low-cost alternatives. Throughout the passage, the author praises the village of Chungungo for taking matters into its own hands in the face of sluggish government bureaucracy, presenting their fog-catching project as an exemplary model of decentralized adaptation to climate change.

Step-by-Step Solution

1
Analyze the passage structure and identify the main argument.
The author contrasts slow-moving, centralized government projects with the immediate success of community-driven fog catchers.
This establishes the core conflict and the author's perspective on localized vs. top-down solutions.
2
Evaluate the author's tone and word choices.
The author uses positive descriptors like 'simple yet innovative,' 'quietly transformed,' and 'taken resource management into their own hands.'
This indicates an admiring and supportive tone toward the local community's initiative and their self-reliance.
3
Differentiate the primary purpose from supporting details and extreme claims.
The physical description of fog catching is a supporting detail, while calling for total replacement of industrial plants is an overstatement not supported by the text.
This eliminates distractors that either focus too narrowly on details or misread the author's moderate, analytical bias.
