Concept:
- A "strong" argument in these Critical Reasoning questions must pass two checks: it must be directly and specifically relevant to the exact issue being debated (not a vague generality), and it must rest on a realistic, reasonable basis rather than mere possibility or speculation.
- Apply both checks to every Roman numeral systematically instead of judging "strong" or "weak" by impression; an argument that fails either check is weak.
Step 1: Test argument I: tourism will attract foreign visitors and boost the economy.
Relevance: it directly addresses the stated goal of fixing the recession through tourism revenue. Realistic basis: tourist spending generating revenue is a standard economic mechanism. It passes both checks -- I is strong.
Step 2: Test argument II: heavy tourism will harm the environment.
Relevance: the passage specifically describes the country as rich in flora and fauna, so environmental damage is a realistic and specific cost of exactly this plan. Realistic basis: ecological strain from heavy tourist inflow is a well-documented effect. It passes both checks -- II is strong.
Step 3: Test argument III: other ways exist to improve the economy.
Relevance: it does not engage with this specific plan at all -- it only asserts that alternatives exist, without naming or evaluating any of them, so it fails the specificity check. III is weak.
Step 4: Test argument IV: tourism helped neighbouring country Y last year.
Relevance: it offers a directly comparable real-world precedent under similar conditions, a neighbouring country facing a similar recession. Realistic basis: a real precedent is solid evidence, not speculation. It passes both checks -- IV is strong.
Step 5: Collect every argument that passed both checks.
Arguments I, II and IV pass both tests, while III fails the relevance check.
Final Answer: Arguments I, II, and IV are strong (Option D)
