Difficulty: MediumIdentification of Main Idea and Supporting Details

Read the passage below carefully:

Traditional Adire textile production in southwestern Nigeria faces dual pressures from low-cost synthetic alternatives and environmental concerns regarding chemical runoff. Standard indigo vat dyeing traditionally relied on natural fermentation processes using indigenous plants and wood ash, creating minimal ecological harm. However, the mid-twentieth century shift toward imported synthetic dyes drastically shortened production cycles while introducing toxic effluents into local waterways. In response, modern artisan collectives are reviving organic fermentation vats integrated with bio-filtration systems. This hybrid approach enables craftspeople to retain the cultural authenticity of intricate resist-patterning while meeting contemporary environmental standards. Crucially, eco-conscious global fashion markets have demonstrated a willingness to pay premium prices for sustainably produced heritage textiles, providing vital financial viability for these revived traditional practices. Thus, ecological innovation in Adire crafting not only mitigates environmental degradation but also secures the economic survival of indigenous textile heritage.

Match each statement from the text on the left with its correct structural role in the passage on the right.

  • Ecological innovation in Adire crafting mitigates environmental harm and secures the economic survival of indigenous textile heritage.Central Thesis / Main Idea synthesized as the ultimate conclusion of the text
  • Modern artisan collectives are reviving organic fermentation vats integrated with bio-filtration systems.Core Supporting Detail presenting the practical solution developed by artisans
  • Eco-conscious global fashion markets demonstrate a willingness to pay premium prices for sustainably produced heritage textiles.Supporting Evidence justifying the economic viability of the eco-friendly approach
  • The mid-twentieth century shift toward imported synthetic dyes introduced toxic effluents into local waterways.Background Context detailing the environmental and historical problem faced

Answer

1. Ecological innovation in Adire crafting mitigates environmental harm and secures the economic survival of indigenous textile heritage → Central Thesis / Main Idea synthesized as the ultimate conclusion of the text.
2. Modern artisan collectives are reviving organic fermentation vats integrated with bio-filtration systems → Core Supporting Detail presenting the practical solution developed by artisans.
3. Eco-conscious global fashion markets demonstrate a willingness to pay premium prices for sustainably produced heritage textiles → Supporting Evidence justifying the economic viability of the eco-friendly approach.
4. The mid-twentieth century shift toward imported synthetic dyes introduced toxic effluents into local waterways → Background Context detailing the environmental and historical problem faced.
The main idea of a passage synthesizes its overall message and purpose. Here, the passage moves from the background problem (pollution from synthetic dyes) to the practical solution (organic fermentation with bio-filtration) and economic justification (market demand for eco-friendly heritage items), culminating in the central thesis that ecological innovation safeguards both environmental health and cultural heritage.

Step-by-Step Solution

1
Analyze the passage structure to locate the main argument.
The final sentence brings together both the environmental and economic threads, framing the overall thesis that ecological innovation preserves both nature and cultural textile heritage.
The main idea unifies the entire passage into a single overarching takeaway.
2
Identify the historical context establishing the issue.
The mention of synthetic dyes introducing toxic pollution sets up the conflict/problem background.
Background context establishes why action or innovation was necessary.
3
Distinguish between the practical action detail and the market evidence detail.
Reviving organic fermentation vats is the action/solution detail, whereas market demand for premium heritage items is the economic evidence supporting its feasibility.
Supporting details provide concrete examples, mechanisms, and evidence that back up the main idea.
