Difficulty: Easy
Correct Answer: If neither conclusion I nor II follows
Explanation:
Introduction / Context:
We must decide whether each conclusion is forced by the premises or merely possible. If a relation can fail under some valid assignment, it does not “follow”.
Given Data / Assumptions:
Concept / Approach:
Translate equalities, then compare ranges implied for A and D relative to C (and E).
Step-by-Step Solution:
From B = C and A ≥ B ⇒ A ≥ C; from C = E and D > C ⇒ D > E = C.
I) E > A? Since A ≥ E(=C), E > A need not hold; indeed A can be > E. Not forced.
II) A < D? We only know A ≥ C and D > C; A could be larger than D (e.g., A=10, C=5, D=6). Not forced.
Verification / Alternative check:
Construct counterexamples: choose C=5, E=5, B=5. Pick A=10 (≥5), D=6 (>5). Then I false (5 > 10 is false) and II false (10 < 6 is false).
Why Other Options Are Wrong:
Neither I nor II is guaranteed; so a/b/c are incorrect.
Common Pitfalls:
Assuming transitivity across unrelated branches (A vs D) without a linking inequality.
Final Answer:
If neither conclusion I nor II follows
