Difficulty: Easy
Choose an option
Answer
Correct Answer: Only conclusion I follows
Explanation
Given data
- Premise 1: All hill stations ⟶ have a sun-set point.
- Premise 2: X is a hill station.
- Conclusions:
- I: X has a sun-set point.
- II: Places other than hill stations do not have sun-set points.
Concept/Approach (why this method)
Apply universal instantiation for X; avoid adding unstated exclusivity ('only hill stations have...').
Step-by-Step calculation / logic1) From Premise 1, any hill station has a sun-set point; since X is one, X has it ⇒ I true.2) Premise 1 does not say non–hill stations lack it; II is an unwarranted converse ⇒ false.
Verification/Alternative
Counterexample to II: A non–hill station city could also have a sun-set viewpoint; premises don’t forbid it.
Common pitfalls
- Reading 'All hill stations have P' as 'Only hill stations have P'.
Final AnswerOnly conclusion I follows.
