Cause & Effect

Key Concepts

# Concept Explanation
1 Cause The event that happens first and is responsible for the second event.
2 Effect The event that happens as a result of the cause; it always follows the cause.
3 Temporal Order Cause must precede effect in time; if B occurs before A, A cannot be the cause of B.
4 Direct Causality A single, clear cause produces a single, clear effect (rare in real-life questions).
5 Multiple Causes An effect may have two or more simultaneous or sequential causes.
6 Immediate vs Remote Cause Immediate cause occurs just before the effect; remote cause lies farther back in the chain.
7 Immediate vs Remote Effect Immediate effect follows instantly; remote effect appears after a gap or through a chain.
8 Coincidence Two events happening together without any causal link—must be eliminated as an option.

15 Practice MCQs

  1. Event (A): The city municipality hiked water tariffs by 25 %. Event (B): Residents installed more rain-water harvesting units. What is the relation? Options:
    A) A is the cause and B is its effect
    B) B is the cause and A is its effect
    C) Both A and B are independent causes
    D) Both A and B are effects of a common cause

Answer: A
Solution: The hike in tariff (A) prompted residents to look for alternatives → harvesting units (B).
Shortcut: Ask “Would B happen without A?” If no → A causes B.
Tag: Direct causality

  1. Event (A): A cyclone warning was issued. Event (B): Coastal schools were closed the same evening. Relation? Answer: A
    Solution: Warning (A) leads to administrative action (B).
    Shortcut: Warning → precaution; always warning first.
    Tag: Immediate cause

  2. Event (A): India won the test series. Event (B): The price of cricket bats sold in local shops rose. Relation? Answer: C

Speed Tricks

Situation Shortcut Example
1 Warning → Action Warning is always first Cyclone warning → school closure
2 Price-hike → Shift to substitute Tariff hike → rain-water harvesting Pick “A causes B”
3 Sentiment vs Supply Sentiment alone rarely changes price Victory → bat price (coincidence)
4 Loss → Relief Loss event first, relief next Crop disease → MSP hike (B causes A)
5 Policy enforcement → Metric change Rule first, statistic later Helmet rule → fatality drop

Quick Revision

Point Detail
1 Cause always happens before effect.
2 If you can insert “because” between two statements, the first is the cause.
3 Common-cause options: look for a third hidden factor.
4 Coincidence = no logical mechanism linking the two.
5 Immediate cause = last link in the chain just before effect.
6 Remote cause = earlier link; may be policy, nature, economy.
7 Sentiment or pride (winning match) ≠ direct cause of price.
8 Government warning/alarm → preventive action (always cause first).
9 Infrastructure creation → long-term usage/economic effect.
10 In twin-statement questions, never pick “independent cause” if one clearly follows the other.
