Statement: The city has banned all private vehicles on weekends.
Judgement I: This will reduce pollution levels.
Judgement II: This will harm emergency services.
Show answer & explanation
Correct answer: D
Explanation
Why is Justification I (pollution incident) invalid?
Banning private vehicles for a weekend (only two days) doesn't result in any lasting or significant reduction in pollution levels. Industrial pollution and public transport continue to operate as usual. Therefore, it's impossible to say with certainty that this decision alone will reduce pollution (it's only a guess, not a logical conclusion).
Why is Justification II (impact on emergency services) invalid?
As we discussed earlier, the ban applies only to 'private' vehicles. Emergency services like ambulances and fire brigades are always exempted from this, so they won't be negatively affected.
Since both justifications are definitely not applicable, you're absolutely right—Option 4 (Neither Justification I nor Justification II is valid) is the most accurate and practical answer.
