Statement–Assumption — “Students are not allowed to wear western dresses on the university campus.” — Vice Chancellor of a reputed university Assumptions: I) Western dresses look vulgar and encourage eve-teasing. II) If girls come in Indian dresses, they will concentrate more on studies. Choose the implicit assumption(s).

Introduction / Context:
A dress-code ban must rest on some presumed harms associated with the prohibited attire. We identify which belief underlies the ban as announced.

Given Data / Assumptions:

• Administration intends to prevent perceived negative outcomes (e.g., harassment).
• Academic focus is influenced by many factors; dress alone is an overreach.

Concept / Approach:
The immediate policy rationale for banning “western dresses” is presumed modesty/safety concerns (rightly or wrongly). The claim that Indian dress improves concentration is speculative and not essential to justify a prohibition framed around propriety or safety.

Step-by-Step Solution:

Verification / Alternative check:
Dress codes are commonly defended on decency/safety grounds rather than cognitive performance claims.

Why Other Options Are Wrong:
“Only II” lacks relevance; “Both” adds a non-essential belief; “Neither” ignores the proximate rationale.

Common Pitfalls:
Assuming every asserted benefit is part of the minimal assumption set.

Final Answer:
Only assumption I is implicit.
