Cause and Effect
Cause and Effect questions involve identifying the relationship between two given statements. One statement represents a cause (reason), and the other represents an effect (result or outcome). The task is to decide whether one statement is the cause of the other, whether both have a common cause, or if they are unrelated.
These problems test logical reasoning, the ability to link events, and understanding of consequence-based relationships.
How to Identify Cause and Effect
- Cause: The initiating event, reason, or action that explains why something happens.
- Effect: The outcome or result that follows from the cause.
Example:
- Cause: Heavy rainfall occurred in the city.
- Effect: The streets got flooded.
Common Scenarios in Cause and Effect Questions
| Scenario | What it Means | Example |
|---|---|---|
| Direct Cause → Effect | One statement clearly leads to the other. | Cause: Power failure occurred. Effect: Trains were delayed. |
| Effect → Cause | One statement explains why the other happened. | Effect: Prices of vegetables increased. Cause: Crop failure due to poor rainfall. |
| Common Cause | Both statements result from the same underlying reason. | Statement 1: Schools declared holiday. Statement 2: Offices remained closed. Cause: City-wide strike. |
| Independent Statements | Both statements are unrelated. | Statement 1: A new bridge was inaugurated. Statement 2: A singer released a new album. |
How to Solve Cause and Effect Questions
-
Check for sequence of events: Ask, “Which one happens first?”
-
Look for dependency: Does one statement explain the other?
-
Test with ‘Why?’ and ‘What happened?’
- If asking “Why?” leads to the other statement, it’s a cause.
- If asking “What happened?” leads to the other statement, it’s an effect.
-
Consider possibility of a common cause: Sometimes neither directly causes the other.
-
Eliminate unrelated statements: If they have no logical connection, mark them independent.
Conceptual Tips and Common Mistakes
- Don’t confuse correlation with causation: Just because two things happen together doesn’t mean one causes the other.
- Check time order: A cause must always occur before its effect.
- Avoid outside knowledge: Base reasoning only on given statements.
- Beware of indirect links: If the link feels forced, they may be independent.
Examples
Example 1 — Direct Cause and Effect
Statement 1: Heavy rains occurred in the city.
Statement 2: Waterlogging was reported in several areas.
Answer: Statement 1 is the cause, Statement 2 is the effect.
Example 2 — Effect → Cause
Statement 1: The market prices of onions increased sharply.
Statement 2: Crop failure occurred due to insufficient rainfall.
Answer: Statement 2 is the cause, Statement 1 is the effect.
Example 3 — Common Cause
Statement 1: Several trains were cancelled.
Statement 2: Flights were also delayed.
Answer: Both are effects of a common cause, such as bad weather.
Example 4 — Independent Statements
Statement 1: A new smartphone model was launched.
Statement 2: The city library was renovated.
Answer: Both are independent events.
