Difficulty: Very hardSummary: Paraphrasing, Synthesis, and Conciseness

Read the passage below carefully:

Rapid urban expansion across West Africa has systematically converted natural vegetation into heat-absorbing concrete surfaces, creating severe urban heat islands. This thermal entrapment not only intensifies localized microclimates but also drastically escalates municipal energy demands and exacerbates respiratory health hazards among vulnerable populations. In response to this environmental degradation, urban planners are adopting targeted green infrastructure initiatives, including vertical gardens and permeable pavements. Consequently, incorporating these eco-friendly architectural strategies mitigates ambient temperatures while establishing long-term economic and ecological resilience in metropolitan centers.

Which of the following represents the correct logical sequence of the synthesized points to form a coherent summary of the passage from cause to ultimate resolution?

  1. 1Unchecked concrete development replaces natural foliage, giving rise to localized urban heat traps.
  2. 2Thermal entrapment escalates energy demands and aggravates public health vulnerabilities.
  3. 3Urban planners introduce green interventions, such as vertical gardens and permeable pavements, to counter the damage.
  4. 4Eco-friendly architecture reduces ambient heat and fosters long-term metropolitan resilience.

Answer

The correct logical sequence places the statement on concrete development and heat traps first, followed by the statement on energy and health impacts, then the statement on urban planners introducing green interventions, and finally the statement summarizing ambient heat reduction and metropolitan resilience.
The correct order follows a clear cause-effect-solution-resolution narrative structure. The summary begins by defining the root cause (concrete replacing vegetation to form heat traps), moves to the direct consequences (escalated energy demands and health hazards), presents the remedial actions (planners introducing green infrastructure), and concludes with the overall synthesis (temperature reduction leading to long-term metropolitan resilience).

Step-by-Step Solution

1
Identify the primary cause described in the passage.
Unchecked replacement of vegetation by concrete surfaces forms the baseline problem statement.
A coherent summary begins with the fundamental cause before addressing effects or solutions.
2
Identify the direct secondary effects resulting from the primary cause.
Increased energy consumption and health hazards directly stem from the heat island effect.
The passage details how thermal entrapment impacts city resources and public health.
3
Identify the specific intervention or corrective action taken.
Urban planners implement green infrastructure such as vertical gardens and permeable pavements.
This marks the transition from problem description to corrective response.
4
Identify the ultimate synthesis and long-term conclusion of the passage.
Green architecture yields ambient cooling and sustainable economic-ecological resilience.
The passage concludes by highlighting the comprehensive long-term resolution.
