In the question below are given two statements followed by two conclusions numbered I and II. You must take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follow (s) from the given statements disregarding commonly known facts. Statements: Some laptops are mobiles. All mobiles are watches. Conclusions: I. Some laptops are watches. II. Some watches are mobiles.

1. A

   Only I follows

2. B

   Only II follows

3. C

   Both I and II follow

4. D

   Neither I nor II follows

Explanation

• Conclusion I is valid because the group of 'laptops' that are 'mobiles' (from Statement 1) must also be 'watches' (as per Statement 2).
• Conclusion II is valid as it is a direct implication of Statement 2 ('All mobiles are watches'). If the entire category of mobiles is within the category of watches, then it must be true that some watches are mobiles.
• Since both conclusions are independently verifiable from the statements, the correct answer is that both follow.

Why Other Options Were Wrong

• Option A: This option is incomplete. While Conclusion I is correct, this choice incorrectly ignores the validity of Conclusion II.
• Option B: This option is incomplete. While Conclusion II is correct, this choice incorrectly ignores the validity of Conclusion I.
• Option D: This option is incorrect because, as demonstrated by logical deduction, both conclusions are valid and directly follow from the given statements.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning (Syllogism) as background academic context rather than a clinical decision trigger.
• While not a clinical question, logical reasoning is a core competency for nurses. It is essential for interpreting patient data, understanding cause-and-effect in pathophysiology, and making sound clinical judgments under pressure.
• This type of deductive reasoning mirrors the process of differential diagnosis, where a nurse must connect symptoms (statements) to potential conditions (conclusions) based on established medical knowledge.
• What if? If Statement 1 were 'No laptops are mobiles,' then Conclusion I ('Some laptops are watches') would not follow, as there would be no guaranteed link between laptops and watches. Conclusion II would still follow from Statement 2.

How to Approach the Question

• Identify the question as a syllogism, which involves premises (statements) and conclusions.
• Treat the given statements as absolute truths, regardless of real-world facts.
• Visualize the relationships between the categories. A Venn diagram is an excellent tool for this.
• Draw the diagram based on the statements: 'All A are B' means circle A is inside circle B. 'Some A are B' means circles A and B overlap.
• Examine each conclusion against your diagram. A conclusion 'logically follows' only if it MUST be true based on the diagram.
• In this case, the diagram for 'Some L are M' and 'All M are W' will clearly show that both conclusions are necessarily true.
