Statement:\n“It is almost impossible to survive and prosper in this world without sacrificing ethics and morality.”\nConclusions:\nI. The world appreciates some ideals but may not uphold them.\nII. The concepts of ethics and morality are not practicable in life.

Introduction / Context:
The premise asserts a pragmatic claim: to both survive and prosper, one almost inevitably has to compromise on ethics and morality. We test which conclusions are necessary implications of that claim.

Given Data / Assumptions:

• “Almost impossible” signals that in practical life, strict adherence to ethics/morality rarely coexists with survival and prosperity.
• No statement is made about what “the world” appreciates in theory.

Concept / Approach:
Conclusion II rephrases the practical thrust: if success and even survival ordinarily demand compromise, then the ideals, in their pure form, are not practicable in real life. By contrast, Conclusion I introduces a new, evaluative claim about collective appreciation that is not present in the text.

Step-by-Step Solution:
1) II tests the practicability of strict ethics: the statement describes a world where strict morality is not feasible alongside survival/prosperity → not practicable → II follows.2) I attributes attitudes (“appreciates but does not uphold”) to “the world,” which is not discussed; the premise comments on practical outcomes, not on attitudes → I does not follow.

Verification / Alternative check:
Had the statement said “people praise ethics but do not practice them,” I would follow. It instead frames a feasibility claim, matching II.

Why Other Options Are Wrong:
Only I: unsupported. Either: wrongly admits I. Both: overstates the evidence.

Common Pitfalls:
Reading implicit moral judgments or social attitudes into a statement about practicality.

Final Answer:
if only Conclusion II follows
