Statement: There is a big boom in the drug trade; many Jhuggi–Jhopri dwellers in Delhi can be seen peddling small pouches of smack and brown sugar. Assumptions: I. Drug addiction is increasing in the country, particularly in the capital. II. All major drug dons live in Jhuggi–Jhopri areas. III. Most Jhuggi–Jhopri dwellers would do anything for money.

Introduction / Context:The statement links a boom in drug business with visible street-level peddling by slum dwellers. We must test which assumptions are necessary for this observation to be meaningful.

Given Data / Assumptions:

• Observed: more pouches being sold openly.
• Implied: rising demand or supply (boom).
• No details on kingpins’ residences or moral character of most residents.

Concept / Approach:Implicit assumptions must not over-generalise beyond what the statement requires.

Step-by-Step Solution:I: A “boom” suggests increased demand/consumption or profitability, especially visible in the capital. Thus I is reasonably implicit.II: Asserting that all big dons live in slums is an extreme generalisation not required for the observation. Not implicit.III: Claiming “most would do anything for money” is a sweeping, value-laden generalisation and not needed. Not implicit.

Verification / Alternative check:The observed peddling could also be supply-driven without any claim about where masterminds live or the morality of most dwellers.

Why Other Options Are Wrong:

• Only II / Only III / I and III: each introduces unnecessary or extreme claims.
• None is implicit: false because I is needed to justify the term “boom”.

Common Pitfalls:Avoid attributing universal motives or residences without textual support.

Final Answer:Only I is implicit.
