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.

I think it depends on what is meant by "some swords are sharp". Does it mean 'at least some swords are sharp' or does it mean 'some swords are sharp and some aren't'? If the former is meant, the answer makes logical sense but if it is meant the latter, both will follow.
