Statement–Assumption — “By 2010, India will be the country with the greatest number of heart patients.” Assumptions: I) It is possible to determine and compare the number of heart patients across countries. II) By 2010, India will be the most populated country in the world. Choose the implicit assumption(s).

Introduction / Context:The prediction ranks India at the top by count of heart patients. To make any cross-country “greatest number” claim, one must assume that the underlying counts are measurable and comparable. Population rank is not strictly necessary for such a medical-burden ranking, because prevalence and risk factors vary.

Given Data / Assumptions:

• Claim: India will have the highest count of heart patients by 2010.
• Assumption I: cross-national counts are obtainable and comparable.
• Assumption II: India will be the most populated country by 2010.

Concept / Approach:Assumption I is necessary: if we could not determine the numbers reliably, a definitive ranking would be baseless. Assumption II is not required: a country can lead in heart-patient counts without being most populous if disease prevalence is higher; conversely, a most populous country might not lead if prevalence is low. The statement never appeals to population ranking; it appeals to absolute case counts.

Step-by-Step Solution:

Verification / Alternative check:Public health comparisons regularly use measured incidence/prevalence databases (registries, surveys) to compare countries; this presupposition matches I, not II.

Why Other Options Are Wrong:“Only II” confuses headcount with population rank; “either” overstates; “neither” ignores the measurability premise; “None of these” would imply both, which is unwarranted.

Common Pitfalls:Assuming demographic dominance is the sole driver of disease burden rankings.

Final Answer:Only Assumption I is implicit.
