Statement:\n“The CBSE has simplified Class X Science and Class XII Mathematics and Physics examination papers,” says the CBSE Director.\nConclusions:\nI. This initiative will greatly improve students’ efficiency.\nII. Simplification is likely to reduce psychological pressure on students.

Introduction / Context:
The Board announces simplification of certain papers. We must see which outcome is a necessary inference rather than a hopeful claim.

Given Data / Assumptions:

• Examination papers have been simplified.
• No performance metrics are provided.

Concept / Approach:
While simplification often aims to lower stress by aligning difficulty and clarity, a guaranteed “great improvement” in efficiency (I) is too strong and not compelled by the text; efficiency depends on multiple factors (teaching quality, preparation, evaluation).

Step-by-Step Solution:
1) II follows: simpler, clearer papers are likely to reduce cognitive load and anxiety, a reasonable logical effect.2) I does not necessarily follow: efficiency gains are speculative without data.

Verification / Alternative check:
If the statement had reported measured gains (“pass rate rose by X% due to simplification”), I could follow. Lacking that, only II is a safe inference.

Why Other Options Are Wrong:
Only I/Either/Neither: each ignores the more conservative, text-aligned inference in II.

Common Pitfalls:
Equating policy intent with guaranteed outcomes.

Final Answer:
if only conclusion II follows
