In logical reasoning, understanding the relationship between events is crucial. One of the most fundamental relationships is Cause and Effect. This concept explains how one event (the cause) leads to another event (the effect). Recognizing this connection helps you analyze statements, solve reasoning problems, and make sound decisions-skills highly valued in competitive exams.
For example, if you hear "Because it rained heavily, the streets flooded," you can see that the heavy rain is the cause, and the flooding is the effect. This simple link between cause and effect forms the backbone of many reasoning questions.
Mastering cause and effect will improve your ability to think critically, identify logical sequences, and avoid common traps in exam questions.
Cause: A cause is an event, action, or condition that directly leads to another event happening. It is the reason something occurs.
Effect: An effect is the result or outcome that happens because of the cause.
In simple terms, the cause is why something happens, and the effect is what happens.

For example, consider the sentence: "Due to heavy traffic, the bus was late."
Here, the heavy traffic caused the bus to be late.
| Type | Definition | Example |
|---|---|---|
| Direct Cause and Effect | The cause leads immediately and clearly to the effect without any intermediate steps. | "The glass fell and broke." |
| Indirect Cause and Effect | The cause leads to the effect through one or more intermediate events. | "Heavy rain caused flooding, which delayed the train." |
| Multiple Causes and Effects | Several causes combine to produce one effect, or one cause results in multiple effects. | "Poor diet and lack of exercise caused health problems." "The earthquake caused damage, injuries, and power outages." |
Step 1: Look for keywords indicating cause and effect. The phrase "Due to" signals a cause.
Step 2: Identify the event before "Due to" as the effect and the event after as the cause.
Step 3: Here, "the football match was postponed" is the effect (what happened), and "heavy rain" is the cause (why it happened).
Answer: Cause = Heavy rain; Effect = Football match postponed.
Step 1: Identify the effect clearly: Increased traffic congestion.
Step 2: List possible causes that contribute to this effect. Common causes include:
Step 3: Understand that these causes may act together to produce the effect.
Answer: Multiple causes such as population growth, increased vehicles, poor infrastructure, and traffic signal issues lead to traffic congestion.
Step 1: Identify the effect: Crop failure.
Step 2: Think about common reasons for crop failure:
Step 3: Conclude that any of these causes or a combination could have led to the crop failure.
Answer: Possible causes include drought, pests, poor soil, or extreme weather.
Assertion: The factory closed down.
Reason: The company faced heavy losses due to poor management.
Determine if the reason correctly explains the assertion.
Step 1: Identify the assertion (effect): Factory closure.
Step 2: Identify the reason (cause): Heavy losses from poor management.
Step 3: Check if the reason logically causes the assertion. Poor management causing losses can lead to factory closure.
Answer: The reason correctly explains the assertion; the cause-effect relationship is valid.
Step 1: Analyze each pair for logical correctness.
Step 2: Option 1: Increased rainfall causing drought is incorrect (opposite effect).
Step 3: Option 2: Traffic jam causing delay is correct.
Step 4: Option 3: Power cut causing more electricity consumption is illogical.
Step 5: Option 4: Lack of exercise causing improved health is incorrect.
Answer: Option 2 is the correct cause-effect pair.
