Critical Reasoning – Interpreting public-health statements: "Cases of food poisoning due to consumption of liquor are increasing in rural areas." Decide which assumption(s) are implicit: (I) The percentage of liquor consumers is higher in rural areas; (II) There are many unauthorized, spurious liquor outlets in rural areas.

Given data

• Observation: Liquor-related food-poisoning cases are rising in rural areas.
• Assumption I: Rural liquor-consumption rate (as a percentage) exceeds that of other areas.
• Assumption II: Rural areas have many unauthorized/spurious liquor shops.

Concept/Approach
The statement reports a trend (increase) within rural areas. It does not compare rural vs. urban consumption percentages, nor does it assert a specific cause.

Step-by-step reasoning
• The increase can occur regardless of whether rural consumption percentage is higher or lower than elsewhere → I is not necessary.• The trend could be due to storage issues, contamination, or episodic illicit brewing; the statement does not require the specific causal claim of widespread spurious outlets → II is not necessary.

Verification/Alternative
Deny I: Even with equal/lower consumption, cases can still rise → statement holds. Deny II: Even with authorized shops, other factors can raise cases → statement holds.

Common pitfalls

• Importing a favored cause into a trend statement without textual support.
• Confusing intra-area trends with inter-area comparisons.

Final Answer
Neither I nor II is implicit.
