Introduction

Multi-Cause → Single Effect पैटर्न उन स्थितियों से जुड़ा है जहाँ एक से अधिक कारण मिलकर एक सामान्य परिणाम पैदा करते हैं। ऐसे प्रश्न यह जाँचते हैं कि क्या आप कई कारणों को पहचानकर यह समझ सकते हैं कि वे मिलकर एक ही observed effect को कैसे उत्पन्न करते हैं। यह प्रकार का reasoning analytical, business और decision-making aptitude tests में अक्सर मिलता है।

Pattern: Multi-Cause → Single Effect

Pattern: Multi-Cause → Single Effect

मुख्य अवधारणा: जब दो या अधिक स्वतंत्र या संबंधित कारक मिलकर एक अंतिम outcome उत्पन्न करते हैं, तो इसे Multi-Cause → Single Effect संबंध कहते हैं।

Step-by-Step Example

Question

1️⃣ किसानों को सूखे की स्थिति का सामना करना पड़ा।
2️⃣ खाद के दाम तेज़ी से बढ़ गए।
3️⃣ कृषि उत्पादन घट गया।

सही संबंध कौन सा है?
(A) 1 & 2 → Causes; 3 → Effect
(B) 3 → Cause; 1 & 2 → Effects
(C) 1 → Cause; 2 & 3 → Effects
(D) 2 & 3 → Causes; 1 → Effect

Solution

  1. Step 1: Contributing factors पहचानें

    सूखा और खाद के दाम बढ़ना - दोनों ही कृषि उत्पादन को नकारात्मक रूप से प्रभावित करते हैं।

  2. Step 2: Probable causes को मिलाएँ

    मौसम की समस्या + उत्पादन लागत बढ़ना → दोनों मिलकर output घटाते हैं।

  3. Step 3: Single effect निर्धारित करें

    उत्पादन में गिरावट दोनों कारणों का संयुक्त अंतिम परिणाम है।

  4. Final Answer:

    1 & 2 → Causes; 3 → Effect → Option A

  5. Quick Check:

    अगर सूखा न होता या खाद के दाम न बढ़ते, तो उत्पादन हानि कम होती - genuine multi-causation साबित होता है ✅

Quick Variations

1. दो असंबंधित घटनाएँ भी एक ही परिणाम तक ले जा सकती हैं।

2. आर्थिक + पर्यावरणीय कारण मिलकर एक observable effect उत्पन्न कर सकते हैं।

3. अक्सर policy impact, social changes या business outcomes आधारित प्रश्नों में मिलता है।

Trick to Always Use

  • Final outcome पहले पहचानें - वही effect होता है।
  • सभी वे factors सूचीबद्ध करें जो उसे logically प्रभावित कर सकते हैं।
  • देखें क्या कारण independent होते हुए भी एक ही परिणाम तक ले जाते हैं।
  • उन options को हटा दें जहाँ sequence उलटा या असंबंधित लगता है।

Summary

  • Multi-Cause → Single Effect में कई कारण मिलकर एक स्पष्ट परिणाम पैदा करते हैं।
  • सुनिश्चित करें कि हर कारण उसी effect से तार्किक रूप से जुड़ता हो।
  • आम उदाहरण: आर्थिक संकट, परीक्षा में असफलता, उत्पादन में देरी आदि।
  • किसी एक कारण को हटाने पर effect कम या टल जाए → यह multi-causation की पुष्टि है।

याद रखने के लिए उदाहरण:
“Drought + High fertilizer prices → Low farm output.”

Practice

(1/5)
1. 1️⃣ The company’s profits dropped this quarter. 2️⃣ Raw material costs increased. 3️⃣ Market demand for products declined. Identify the correct cause-effect relationship.
easy
A. 1 & 2 → Causes; 3 → Effect
B. 2 & 3 → Causes; 1 → Effect
C. 1 → Cause; 2 & 3 → Effects
D. All are independent

Solution

  1. Step 1: Identify possible causes

    Rising input costs and lower product demand both reduce profit margins.

  2. Step 2: Determine the effect

    The company’s profit drop is the combined outcome.

  3. Step 3: Logical link

    Both 2 and 3 are causes → 1 is the effect.

  4. Final Answer:

    2 & 3 → Causes; 1 → Effect → Option B

  5. Quick Check:

    Removing either cause could reduce loss severity ✅
Hint: Multiple economic factors can combine to produce one business effect.
Common Mistakes: Considering only one cause or reversing the sequence.
2. 1️⃣ Traffic congestion worsened in the city. 2️⃣ Several roads are under repair. 3️⃣ The number of vehicles increased rapidly. Choose the correct cause-effect relationship.
easy
A. 2 & 3 → Causes; 1 → Effect
B. 1 → Cause; 2 & 3 → Effects
C. 3 → Cause; 1 & 2 → Effects
D. All are effects of a common cause

Solution

  1. Step 1: Identify factors

    Road repairs and more vehicles both logically increase traffic congestion.

  2. Step 2: Determine result

    Congestion is the outcome (effect).

  3. Step 3: Direction check

    2 & 3 → Causes; 1 → Effect.

  4. Final Answer:

    2 & 3 → Causes; 1 → Effect → Option A

  5. Quick Check:

    Less roadwork or fewer vehicles → smoother traffic ✅
Hint: When two issues together explain one city problem, it’s a multi-cause situation.
Common Mistakes: Assuming congestion caused more vehicles or repairs.
3. 1️⃣ Students performed poorly in exams. 2️⃣ Many skipped classes frequently. 3️⃣ The syllabus was not fully covered by teachers. Identify the correct relation.
easy
A. 1 → Cause; 2 & 3 → Effects
B. 2 & 3 → Causes; 1 → Effect
C. 1 & 2 → Causes; 3 → Effect
D. All are independent

Solution

  1. Step 1: Identify probable reasons

    Irregular attendance and incomplete syllabus coverage both lead to poor performance.

  2. Step 2: Logical combination

    2 & 3 jointly cause 1.

  3. Step 3: Validation

    Each cause contributes to the same academic result.

  4. Final Answer:

    2 & 3 → Causes; 1 → Effect → Option B

  5. Quick Check:

    Better attendance or full coverage → improved results ✅
Hint: Multiple academic issues often explain one poor outcome.
Common Mistakes: Treating ‘poor performance’ as a cause instead of result.
4. 1️⃣ Several trees were uprooted. 2️⃣ The city faced heavy rainfall. 3️⃣ Wind speeds crossed 100 km/h. Identify the correct cause-effect sequence.
medium
A. 1 → Cause; 2 & 3 → Effects
B. 2 & 3 → Causes; 1 → Effect
C. All are effects of a common cause
D. 1 & 2 → Causes; 3 → Effect

Solution

  1. Step 1: Determine contributing factors

    Strong winds and heavy rain together lead to trees being uprooted.

  2. Step 2: Define the outcome

    Tree damage is the effect.

  3. Step 3: Logical order

    2 & 3 are causes → 1 is the effect.

  4. Final Answer:

    2 & 3 → Causes; 1 → Effect → Option B

  5. Quick Check:

    No rain or wind → no tree damage ✅
Hint: When natural conditions combine to produce destruction, it’s multi-cause reasoning.
Common Mistakes: Seeing one cause in isolation and ignoring combined effect.
5. 1️⃣ The number of internet users increased sharply. 2️⃣ Smartphone prices dropped. 3️⃣ Mobile data became cheaper. Identify the correct multi-cause-effect relation.
medium
A. 2 & 3 → Causes; 1 → Effect
B. 1 & 2 → Causes; 3 → Effect
C. All are independent
D. 1 → Cause; 2 & 3 → Effects

Solution

  1. Step 1: Identify potential causes

    Falling smartphone prices and cheaper data encourage internet adoption.

  2. Step 2: Determine the effect

    Increase in users (1) is the outcome.

  3. Step 3: Confirm logical direction

    2 & 3 are causes → 1 is effect.

  4. Final Answer:

    2 & 3 → Causes; 1 → Effect → Option A

  5. Quick Check:

    Higher data cost or expensive phones → fewer users ✅
Hint: When affordability factors combine to raise adoption, both are valid causes.
Common Mistakes: Choosing only one factor instead of recognizing both causes.
