A cause is the reason something happens. An effect is what happens because of that reason
✏️Example
Rain (cause) makes the ground wet (effect)
💡KEY RULES
Cause always comes first in time. Effect comes after.
2. One event must directly lead to the other—there must be a real connection.
3. Correlation is NOT causation.
Just because two things happen together doesn't mean one caused the other.
4
→Look for trigger words
because, since, caused by, due to, as a result, therefore, consequently, led to.
5. A single cause can have multiple effects. A single effect can have multiple causes.

Exam Patterns
What examiners ask — read before attempting PYQs
SSC CGL asks cause-effect questions in two main ways:
- Find the cause of a given effect
- Identify what effect follows from a given cause
- Distinguish between real cause-effect and mere coincidence
- Spot faulty cause-effect reasoning
SHORTCUT/TRICK:
Use the "IF-THEN" test: If [cause happens], then [effect should happen]. If this sounds logical and the connection is direct, it's likely correct. If the connection feels forced or needs extra steps, it's probably wrong.

Worked Example
Solve this step-by-step before moving on
1
Step 1
Identify the claimed cause—new machinery installation.
2
Step 2
Identify the claimed effect—40% productivity increase.
3
Step 3
Check if cause came before effect—YES, machinery installed first, then productivity increased.
4
Step 4
Check if there's a direct connection—The passage assumes machinery automatically increases productivity, but doesn't prove it. Workers might be working harder due to new job expectations, or the month itself could be naturally busy.
5
Step 5
Look for alternative causes—Training on machinery, worker motivation, seasonal demand, management changes.
Conclusion: The reasoning is WEAK. It shows correlation but not proven causation. Other factors could explain the effect.
COMMON MISTAKE:
Students assume that because Event A happened before Event B, A caused B. This is wrong. Sequence alone doesn't prove causation. You need a logical, direct connection. Also, students miss alternative explanations. Always ask: "Could something else have caused this effect?"
