Correct Answer: Only conclusion II follows
Explanation:
Since the middle term 'chalks' is not distributed even once in the premises, no definite conclusion follows. However, II is the converse of the first premise and so it holds.
Correct Answer: Only conclusion I follows
Explanation:
Since both the premises are universal and one premise is negative, the conclusion must be universal negative and should not contain the middle term. So, only I follows.
Correct Answer: Only conclusion II follows
Explanation:
Since one premise is particular, the conclusion must be particular and should not contain the middle term. Thus, only II follows.
Correct Answer: Both I and II follow
Explanation:
Since both premises are particular, no definite conclusion follows. However, I is the converse of second premise, while II is the converse of the first premise. So, both of them hold.
Correct Answer: Only conclusion II follows
Explanation:
Since the middle term 'tall' is not distributed even once in the premises, no definite conclusion follows. However, II is the converse of the second premise and so it holds.
Correct Answer: Only conclusion I follows
Explanation:
Since the middle term 'engineer' is not distributed even once in the premises, no definite conclusion follows. However, I is the converse of the first premise and thus it holds.
Correct Answer: Both I and II follow
Explanation:
Since both the premises are universal and one premise is negative, the conclusion must be universal negative. Also, the conclusion should not contain the middle term. So, I follows. However, II is the converse of the second premise and thus it also holds,
Correct Answer: Only conclusion I follows
Explanation:
Since both the premises are particular, no definite conclusion follows. However, I is the converse of the second premise and thus it holds.
Correct Answer: Only conclusion I follows
Explanation:
Since on premise is negative, the conclusion must be negative. Conclusion II cannot follow as it contains the middle term. So, only I follows.
Correct Answer: Either I or II follows
Explanation:
As discussed above, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some books are not pencils'. However, I and II involve only the extreme terms and form a complementary pair. Thus, either I or II follows.
