Difficulty: Easy
Correct Answer: If only conclusion I follows
Explanation:
Introduction / Context:
We must propagate inequalities through a chain to test conclusions.
Given Data / Assumptions:
Concept / Approach:
From T < M and M < J, we infer T < J. No direct relation compares J and Z from the given set.
Step-by-Step Solution:
T < M and M < J ⇒ T < J (I true).
Z > T does not fix J vs Z (II not provable).
Verification / Alternative check:
Counterexample for II: pick values T=0, M=1, J=2, Z=1.5; then J (2) is not < Z (1.5).
Why Other Options Are Wrong:
II does not necessarily hold; only I follows.
Common Pitfalls:
Assuming transitivity across unrelated branches.
Final Answer:
If only conclusion I follows
