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?
- ABitumen emulsion and lime can be added to traditional soil mixtures to solve the moisture sensitivity of sun-dried earth bricks.
- Adapting traditional earth architecture with modern stabilisers offers an energy-efficient alternative to concrete urban housing in northern Nigeria.Cevap
- CContemporary urban planners in Sokoto have officially banned concrete infrastructure in favor of traditional tubali construction for public housing.
- DModern concrete infrastructure in northern Nigeria relies on sun-dried earth bricks to maintain cooler indoor temperatures during peak heat waves.
