Statements: Some lions are tigers. No tiger is deer. Conclusions: I. Some lions are not deer. II. All lions are deer.
Correct answer: B. Neither
- A. Only I
- B. Neither
- C. Only II
- D. Both
Explanation
In logical deduction, we examine whether the conclusions necessarily follow from the given statements. Statement 1 tells us that some lions are tigers, and statement 2 tells us that no tiger is a deer. Conclusion I suggests that some lions are not deer, which seems plausible because the lions that are tigers cannot be deer. However, without further information, we cannot definitively conclude that this is true for some lions not being deer. Conclusion II claims that all lions are deer, which is clearly false as some lions are tigers and no tigers are deer. Therefore, neither conclusion follows logically from the given statements. Conclusion I cannot be fully validated, and conclusion II is directly contradicted by the statements. Hence, the correct choice is 'Neither'.

About Logical Deductions
Logical deductions require conclusions to be drawn from stated facts, conditions and relationships without adding outside information. The work includes handling all, some and none statements, necessary and sufficient conditions, ordering restrictions, true or false conclusions, and the difference between what must be true and what could be true.
