-
BOnly assumption II is implicit

-
DNeither I nor II is implicit
-
EBoth I and II are implicit
Answer
Correct Answer: Only assumption I is implicit
Explanation
Introduction / Context:The claim “cost of living has gone up” refers to general living expenses. We must identify what the speaker must believe for this to be a sensible conclusion.
Given Data / Assumptions:
- I: The prices of essential commodities have gone up in recent times.
- II: Many luxury goods are available in plenty in the country.
Concept / Approach:Cost of living is primarily affected by essential goods and services (food staples, rent, utilities, transport). Availability of luxury goods does not directly determine the cost of living.
Step-by-Step Solution:1) If essentials cost more, then maintaining the same standard of living becomes more expensive—this underpins the statement. Hence assumption I is necessary.2) Assumption II concerns luxury abundance, which may occur alongside high or low costs of living. It is neither necessary nor sufficient to justify the claim.3) Negate I: If essential prices have not risen, the blanket statement “cost of living has gone up” becomes doubtful.4) Negate II: Even if luxury items are scarce, the cost of living could still rise due to essentials. Thus II is irrelevant.
Verification / Alternative check:Check CPI logic: CPI baskets are dominated by essentials. A rise in these categories validates the speaker’s statement; luxury good availability does not.
Why Other Options Are Wrong:
- Only II / Both / Either: II does not support the cost-of-living claim.
- Neither: I is indeed required.
Common Pitfalls:Do not equate “more luxury goods” with “higher living cost.” These are different economic indicators.
Final Answer:Only assumption I is implicit
