Sequential / Chain Cause–Effect

Introduction

In many real-world situations, one event leads to another, creating a continuous chain of cause and effect. This pattern is crucial in reasoning exams because it tests your ability to identify how a sequence of linked events unfolds logically - where one event’s effect becomes the next event’s cause.

Pattern: Sequential / Chain Cause–Effect

Pattern

The key concept is: one event triggers another, forming a chain where the effect of the first event becomes the cause of the next.

Step-by-Step Example

Question

1️⃣ Heavy rain flooded the roads.
2️⃣ Traffic movement came to a halt.

Which of the following correctly represents the relationship?
(A) 1 → Cause; 2 → Effect
(B) 2 → Cause; 1 → Effect
(C) Chain cause-effect (1 causes 2)
(D) Both are independent

Solution

  1. Step 1: Identify event order

    First, heavy rain occurred → then roads flooded → then traffic stopped. Clearly, a sequence exists.

  2. Step 2: Analyze connection

    Rain (cause) → Flooding (effect) → becomes next cause → Traffic stopped (final effect).

  3. Step 3: Identify pattern

    It’s not just one cause and one effect - it’s a chain of causes and effects.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option C

  5. Quick Check:

    If rain hadn’t occurred, roads wouldn’t flood and traffic wouldn’t stop ✅

Quick Variations

1. May involve 2-3 linked events in natural, economic, or social contexts.

2. Often used in analytical reasoning where one event sets off a chain reaction.

3. Requires tracing the full sequence logically to find the starting cause and final effect.

Trick to Always Use

  • Find the root cause that started the sequence.
  • Check if the effect of one event becomes the cause of the next.
  • Visualize the chain: A → B → C, then identify each link clearly.

Summary

Summary

  • Sequential or Chain Cause-Effect means events are connected stepwise.
  • The first event starts the chain, and the last event is the ultimate result.
  • Used when each event depends on the previous one logically.
  • Focus on chronological and logical order to avoid confusion.

Example to remember:
Heavy Rain → Roads Flood → Traffic Halt → Chain Cause-Effect.

Practice

(1/5)
1. 1️⃣ A fire broke out in the factory. 2️⃣ The production came to a halt. Identify the correct cause-effect chain.
easy
A. 2 → Cause; 1 → Effect
B. Both are independent
C. Chain cause–effect (1 causes 2)
D. Both are effects of a common cause

Solution

  1. Step 1: Examine event order

    The fire happened first, and as a result, the factory stopped production.

  2. Step 2: Identify link

    Fire → Production Halt - a direct cause-effect chain.

  3. Step 3: Confirm logic

    One event clearly triggers the next.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option C

  5. Quick Check:

    No fire → production continues ✅
Hint: When one event disrupts another, it’s a chain cause-effect.
Common Mistakes: Marking it as direct cause-effect without recognizing sequential dependency.
2. 1️⃣ Heavy snowfall blocked highways. 2️⃣ Supplies to hill towns were delayed. Identify the relationship between the two.
easy
A. 1 → Cause; 2 → Effect
B. Chain cause–effect (1 causes 2)
C. Both are independent
D. Both are effects of a common cause

Solution

  1. Step 1: Identify sequence

    Snowfall occurred first, causing highway blockages, leading to supply delays.

  2. Step 2: Establish link

    Snowfall → Blockage → Delay → a continuous chain.

  3. Step 3: Conclude

    This is a chain cause-effect pattern.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option B

  5. Quick Check:

    No snow → roads open → no delay ✅
Hint: Natural event → blockage → delay forms a clear sequence.
Common Mistakes: Selecting simple cause-effect instead of chain pattern.
3. 1️⃣ The company increased product prices. 2️⃣ The demand fell significantly. Identify the logical relation.
easy
A. Chain cause–effect (1 causes 2)
B. 2 → Cause; 1 → Effect
C. Both are independent
D. Both are effects of a common cause

Solution

  1. Step 1: Check sequence

    Price rise happened first, leading to fall in demand.

  2. Step 2: Identify pattern

    Price ↑ → Demand ↓ - direct but sequential chain.

  3. Step 3: Logical direction

    Higher prices cause reduced sales, which may cause losses later.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option A

  5. Quick Check:

    Lower prices → demand increases ✅
Hint: Economic decisions often create sequential effects on demand.
Common Mistakes: Treating demand fall as independent of pricing.
4. 1️⃣ A computer virus infected the system. 2️⃣ Important files were lost. Identify the correct cause-effect chain.
medium
A. 1 → Cause; 2 → Effect
B. Chain cause–effect (1 causes 2)
C. Both are effects of a common cause
D. Both are independent

Solution

  1. Step 1: Analyze order

    Virus enters first → damages system → files lost.

  2. Step 2: Establish chain

    Infection (cause) → corruption (intermediate cause) → loss (effect).

  3. Step 3: Identify pattern

    This is a sequential chain of events.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option B

  5. Quick Check:

    No virus → no data loss ✅
Hint: Look for intermediate actions linking cause and effect.
Common Mistakes: Marking only direct cause-effect without recognizing the chain.
5. 1️⃣ The government imposed higher import duties. 2️⃣ The prices of imported goods increased. Identify the correct cause-effect type.
medium
A. Both are effects of a common cause
B. Chain cause–effect (1 causes 2)
C. 2 → Cause; 1 → Effect
D. Both are independent

Solution

  1. Step 1: Observe sequence

    Import duty increased first → import costs rose → prices increased.

  2. Step 2: Identify the chain

    Duty ↑ → Cost ↑ → Price ↑ - clear chain cause-effect.

  3. Step 3: Conclude

    This represents a sequential causal relationship.

  4. Final Answer:

    Chain cause-effect (1 causes 2) → Option B

  5. Quick Check:

    No duty hike → prices stable ✅
Hint: Policy decisions often create stepwise economic effects.
Common Mistakes: Confusing it with direct cause-effect instead of sequential link.
