Statements: Some swords are sharp. All swords are rusty
Conclusions:
- Some rusty things are sharp.
- Some rusty things are not sharp.
Answer: Option
Explanation:
Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, I follows. Since both the premises are affirmative, the conclusion cannot be negative. Thus, II does not follow.

The statement "Some swords are sharp" only tells about some swords being sharp but it does not imply that some swords are not sharp. This statement is true even if all the swords are sharp. Because if all the swords are sharp, then definitely some swords are sharp. By extension of this logic, all the rusty (things) may also be sharp. Hence conclusion II is not true.
(A conclusion that is false in even one case is basically false overall).
(A conclusion that is false in even one case is basically false overall).
