Assumption identification in a data-based claim: The statement says "Of all newspapers published in Mumbai, readership of the 'Times' is the largest in the metropolis." Decide which assumption(s) follow (I: 'Times' is not popular in mofussil areas; II: 'Times' has a popular cartoons feature on current issues).

Given data

• Claim: In Mumbai (the metropolis), 'Times' has the largest readership among local newspapers.
• Assumption I: 'Times' is not popular in mofussil (non-metro) areas.
• Assumption II: 'Times' carries popular cartoons on burning issues.

Concept/Approach
An assumption must be necessary for the stated comparative claim about metro readership. Irrelevant details about other regions or specific features are not required unless the claim would otherwise fail.

Step-by-step reasoning
1) The statement is purely city-specific (Mumbai readership ranking).2) Popularity in mofussil areas (I) does not affect the metro ranking; hence I is not necessary.3) Having cartoons (II) is at best a possible reason for popularity; the ranking can hold for many other reasons (news coverage, circulation network). Thus II is not required.

Verification/Alternative
We can imagine the ranking being true whether or not mofussil popularity exists and whether or not cartoons are present. So neither assumption is indispensable.

Common pitfalls

• Confusing sufficient reasons (cartoons) with necessary assumptions.
• Extending a metro-specific claim to non-metro contexts.

Final Answer
Neither I nor II is implicit.
