Options- A. Only conclusion I follows
- B. Only conclusion II follows
- C. Either I or II follows

- Correct Answer
- Only conclusion I follows
ExplanationSince one premise is particular, the conclusion must be particular and should not contain the middle term. Thus, it follows that 'Some pastries are chocolates', I is the converse of the second premise and so it holds. Since both the premises are affirmative, the conclusion cannot be negative. Thus, II does not follow. - 1. Statements: All young scientists are open-minded. No open-minded men are superstitious.

Correct Answer: Neither I nor II follows
Explanation:
The subject in both the conclusions is vague. The true conclusion is 'No young scientist is superstitious'. Thus, neither I nor II follows,
Correct Answer: Only conclusion I follows
Explanation:
Since both the premises are universal and affirmative, the conclusion must be universal affirmative. However, conclusion II, being an A-type proposition, distributes the term 'cats'.
Since the term 'cats' is distributed in II without being distributed in any of the premises, so conclusion II cannot follow. Thus, only I follows.
Since the term 'cats' is distributed in II without being distributed in any of the premises, so conclusion II cannot follow. Thus, only I follows.
Correct Answer: Neither I nor II follows
Explanation:
Since the middle term 'divine' is not distributed even once in the premises, no definite conclusion can be drawn.
Correct Answer: Both I and II follow
Explanation:
Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, II follows. I is the converse of II and so it also holds.
Correct Answer: Only conclusion I follows
Explanation:
Since one premise is particular and the other premise is negative, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some desks are not red'. However, I is the converse of the first premise and thus it holds.
Correct Answer: Neither I nor II follows
Explanation:
Both the premises are A type propositions. So, the middle term 'honest' forming the predicate in each is not distributed in either. Since the middle term is not distributed even once, no definite conclusion follows.
Correct Answer: Only conclusion II follows
Explanation:
Since both the premises are universal and affirmative, the conclusion must be universal affirmative and should not contain the middle term. So, it follows that 'All pens are houses'. II is the converse of this conclusion and so it holds. Since the term 'houses' is distributed in I without being distributed in any of the premises, so I does not follow.
Correct Answer: Neither I nor II follows
Explanation:
Since the middle term 'smokers' is not distributed even once in the premises, no definite conclusion follows.
Correct Answer: Neither I nor II follows
Explanation:
Since the middle term 'cats' is not distributed even once in the premises, no definite conclusion follows.
