Difficulty: Easy
Correct Answer: If only conclusion I follows
Explanation:
Introduction / Context:
We must see what is compelled about J vs I and Y vs R, given J equals P and P is at least R, which is strictly above I.
Given Data / Assumptions:
Concept / Approach:
From R > I and J = P ≥ R, J must be > I. But Y < J tells nothing definitive about Y vs R because R could be below or equal to J while Y might still be above or below R.
Step-by-Step Solution:
I) Since J = P ≥ R > I ⇒ J > I (true).
II) From Y < J and R ≤ J, Y could be < R or > R depending on values. Not forced.
Verification / Alternative check:
Counterexample for II: Y=100, R=50, J=P=101, I any <50. Then Y > R, so II fails while premises hold.
Why Other Options Are Wrong:
Only I is certain; II is not determined.
Common Pitfalls:
Assuming “Y < J and R ≤ J” implies Y < R; it does not.
Final Answer:
If only conclusion I follows
