Difficulty: HardSummary: Paraphrasing, Synthesis, and Conciseness

Read the passage below carefully:

The rapid expansion of urban concrete infrastructure in northern Nigerian cities like Sokoto has systematically displaced traditional *tubali* (sun-dried earth brick) architecture, creating microclimates dependent on energy-heavy air conditioning. While contemporary urban planners often dismiss earth construction as fragile or archaic, recent thermal dynamics studies demonstrate that *tubali* structures possess superior thermal mass, effectively dampening interior temperature spikes during peak heat waves. Incorporating modern non-toxic stabilisers like bitumen emulsion or lime into traditional soil mixes rectifies moisture sensitivity while preserving natural cooling properties. Consequently, integrating refined *tubali* engineering into contemporary public housing schemes offers a viable, low-carbon alternative to synthetic cooling in Sahelian urban design.

Which of the following statements best synthesizes the main argument of the passage?

  1. A
    Bitumen emulsion and lime can be added to traditional soil mixtures to solve the moisture sensitivity of sun-dried earth bricks.
  2. Adapting traditional earth architecture with modern stabilisers offers an energy-efficient alternative to concrete urban housing in northern Nigeria.Answer
  3. C
    Contemporary urban planners in Sokoto have officially banned concrete infrastructure in favor of traditional tubali construction for public housing.
  4. D
    Modern concrete infrastructure in northern Nigeria relies on sun-dried earth bricks to maintain cooler indoor temperatures during peak heat waves.

Answer

Adapting traditional earth architecture with modern stabilisers offers an energy-efficient alternative to concrete urban housing in northern Nigeria.
The correct answer effectively synthesizes the passage's primary claim: that modernized traditional earth architecture (tubali) serves as a low-carbon, energy-efficient solution to urban heat and concrete dependence in northern Nigeria.

Step-by-Step Solution

1
Identify the core problem presented in the text.
Urban concrete expansion in northern Nigeria increases reliance on energy-intensive cooling.
Establishes the background conflict of the passage.
2
Identify the proposed solution and technological refinement.
Traditional earth bricks (tubali) provide superior thermal mass, and adding modern stabilisers removes their moisture vulnerability.
Combines the evidence and technical adaptation mentioned in the text.
3
Determine the concluding thesis (synthesis).
Integrating updated tubali engineering into urban housing provides a sustainable alternative to synthetic cooling.
Captures the ultimate point of the entire passage without over-relying on minor supporting details or unstated assumptions.
