Introduction
Cause and Effect RC आपकी यह क्षमता परखता है कि आप समझ सकें कि क्यों कुछ हुआ (cause) और उसका परिणाम क्या हुआ (effect)। CAT, SSC CGL, IBPS PO, और CUET जैसे competitive exams में ऐसे प्रश्न अक्सर पूछे जाते हैं, जिनमें आपको events, actions, decisions या phenomena के बीच संबंध पहचानना होता है। इन links को समझने से आप लेखक की logical structure और reasoning को बेहतर तरीके से समझ पाते हैं।
Pattern: Cause and Effect RC
Pattern
मुख्य विचार यह है कि किस घटना को क्या trigger करता है (cause) और वह किस परिणाम तक पहुँचती है (effect)। Complex passages में causes और effects अलग-अलग paragraphs में बिखरे हो सकते हैं, सीधे न बताकर indirectly imply किए जा सकते हैं, या contrasting viewpoints के बीच छुपे हो सकते हैं। इन connections को समझना inference, factual validation और logical sequence जैसे questions में मदद करता है।
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
-
Step 1: Identify the stated cause
Passage में साफ बताया गया है कि wetlands को concrete structures से बदलने से भूमि की water absorption क्षमता काफी कम हो गई है।
-
Step 2: Connect cause to effect
Absorption कम → waterlogging ज़्यादा → urban flooding बढ़ती है।
-
Step 3: Eliminate irrelevant options
A, C और D का flooding से कोई संबंध passage में नहीं बताया गया।
-
Final Answer:
Replacement of wetlands with concrete structures → Option B -
Quick Check:
Wetlands खोए → absorption घटी → flooding बढ़ी। Passage से बिल्कुल match करता है। ✔️
Quick Variations
- Direct causes और indirect causes पहचानना
- Multi-cause और multi-effect chains समझना
- Correlation और causation में फर्क करना
- Cause-effect अलग paragraphs में ढूँढना
Trick to Always Use
- Signal phrases देखें: “due to”, “as a result”, “because”, “therefore”, “consequently”.
- चेक करें कि कोई घटना logically दूसरे effect तक पहुँचती है या नहीं।
- Examples के बीच छिपे secondary causes पर ध्यान दें।
Summary
Summary
- Cause = क्यों कुछ हुआ; Effect = उसका परिणाम क्या हुआ।
- Explicit और implied दोनों causal links पर ध्यान दें।
- देखें कि passage में multiple contributing factors बताए गए हैं या नहीं।
- Correlation और true causation में भ्रम न करें।
याद रखने का example:
“Clogged drains + intense rainfall” → Combined cause leading to flooding.
