Cause and Effect RC

Introduction

Cause and Effect RC tests your ability to understand why something happened (cause) and what happened as a result (effect). Competitive exams like CAT, SSC CGL, IBPS PO, and CUET frequently include questions that require identifying relationships between events, actions, decisions, or phenomena. Recognising these links helps you interpret the author’s logical structure and reasoning.

Pattern: Cause and Effect RC

Pattern

The key idea is to identify what triggered an event (cause) and what outcome it produced (effect). In complex passages, causes and effects may be spread across paragraphs, implied indirectly, or hidden between contrasting viewpoints. Understanding these connections helps in answering inference, factual validation, and logical sequence questions.

Step-by-Step Example

Question

Over the past decade, urban flooding has become increasingly common in several rapidly growing cities across Asia and Africa. A 2023 Global Climate Resilience Study noted that many of these cities have expanded faster than their drainage and water-management systems can cope with. As commercial centres, residential high-rises, and paved industrial corridors have replaced wetlands and open soil, the natural ability of land to absorb rainfall has been drastically reduced. As a result, even moderate showers often lead to waterlogging and traffic paralysis.

Another contributing factor is the rise in short-duration, high-intensity rainfall events linked to changing monsoon patterns. Meteorological researchers explain that warmer ocean temperatures increase atmospheric moisture, causing sudden bursts of rainfall. In cities where drains are clogged with plastic waste and construction debris, these intense downpours overwhelm the system within minutes. Consequently, floodwaters rise quickly, affecting public transport, small businesses, and low-income settlements located along riverbanks and poorly planned drainage zones.

The study highlights that economic losses from urban flooding extend far beyond physical damage. Repeated flooding disrupts daily wage work, delays supply chains, and reduces productivity in service-based industries. Insurance premiums rise, public health risks increase, and municipal budgets get redirected from long-term infrastructure projects to emergency relief measures. Urban planners warn that unless cities invest in sustainable drainage systems, wetland restoration, stricter construction regulation, and effective waste management, these annual disruptions will escalate in severity in the coming years.

Overall, the findings suggest that both environmental and human-induced factors combine to worsen urban flooding. While climate change has intensified rainfall patterns, unplanned development and poor waste management have multiplied the impact-turning severe weather into recurring urban disasters.


According to the passage, what is one major cause of frequent urban flooding?

Options:

  • A: High taxation in metropolitan cities
  • B: Replacement of wetlands with concrete structures
  • C: Increase in foreign investment
  • D: Shortage of public buses

Solution

  1. Step 1: Identify the stated cause

    The passage clearly states that replacing wetlands with concrete reduces the land’s ability to absorb rainfall.

  2. Step 2: Connect cause to effect

    Reduced absorption leads to waterlogging → contributes to urban flooding.

  3. Step 3: Eliminate irrelevant options

    A, C, and D have no connection to flooding in the passage.

  4. Final Answer:

    Replacement of wetlands with concrete structures → Option B

  5. Quick Check:

    Wetlands lost → less absorption → frequent flooding. Matches the passage perfectly. ✔️

Quick Variations

- Identifying direct causes vs. indirect causes

- Multi-cause and multi-effect chains

- Distinguishing correlation from causation

- Cause-effect spread across different paragraphs

Trick to Always Use

  • Locate signal phrases: “due to”, “as a result”, “because”, “therefore”, “consequently”.
  • Check whether the event described logically leads to the effect stated.
  • Look for secondary causes hidden between examples.

Summary

Summary

  • Cause = why something happens; Effect = what results from it.
  • Look for both explicit and implied causal links.
  • Check if the passage mentions multiple contributing factors.
  • Avoid confusing coincidence or correlation with true causation.

Example to remember:
“Clogged drains + intense rainfall” → Combined cause leading to flooding.

Practice

Over the last fifteen years, agricultural productivity in several developing countries has fluctuated sharply due to a combination of climatic stress and policy-related disruptions. A 2024 Food Systems Stability Report notes that erratic monsoon patterns, prolonged dry spells, and unexpected heat waves have reduced crop yields across major farming belts in Africa and South Asia. These climatic shocks often coincide with delayed government procurement, unstable minimum support prices, and limited access to crop insurance. As a result, farmers frequently experience income volatility, forcing many to reduce investments in high-quality seeds and fertilizers the following season.<br><br>The report also highlights how supply-chain bottlenecks amplify the impact of poor harvests. In regions where rural roads remain underdeveloped, transporting perishable produce becomes risky during extreme weather. Small traders incur additional logistical costs, which they pass on to consumers, causing sudden spikes in food prices. This inflation is especially severe in areas dependent on single-season crops, where one failed harvest disrupts market stability for months.<br><br>Another factor contributing to recurring agricultural distress is groundwater depletion. In states where farmers rely heavily on borewells, years of over-extraction have lowered water tables to alarming levels. When heat waves arrive earlier than expected, remaining groundwater evaporates rapidly, leaving farmers without sufficient irrigation for mid-season growth. This leads to partial crop losses even when initial sowing conditions were favourable.<br><br>Experts argue that the combination of climatic risks, weak market infrastructure, and resource depletion creates a cycle of instability. Farmers struggling with reduced yields invest less the next year, leading to poorer harvests and higher market prices. Policymakers warn that unless governments prioritise climate-resilient seeds, rural logistics, and water-management reforms, agricultural volatility will intensify in the coming decade.
