Question
Statements: I. The government has raised the price of petrol sharply. II. Sales of electric scooters have risen this quarter.
Which best describes the relation?
Options
- I is the cause and II is its effect
- II is the cause and I is its effect
- Both are independent causes
- Both are effects of a common cause
Show the answer and the worked solution
Correct answer: A. I is the cause and II is its effect
Worked solution
- A sharp rise in petrol prices makes petrol vehicles costlier to run.
- That pushes buyers towards electric alternatives, so sales rise.
- I is the cause and II is its effect.
Answer: I is the cause and II is its effect.
The idea
Check the direction of plausibility and the timing. Scooter sales cannot raise petrol prices, which rules out the reverse reading.
Shortcut. One statement is a government decision and the other a market figure; a price set by the government drives buyers' choices, never the reverse, so I causes II.
Common trap. "Both are effects of a common cause" — a fuel crisis could explain both, but the statements show a direct link: dearer petrol pushes buyers to electric scooters.
