Statements: All bags are cakes. All lamps are cakes.
Conclusions:
- Some lamps are bags.
- No lamp is bag.
Answer: Option
Explanation:
Since the middle term 'cakes' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. So, either I or II follows.

If we use Venn diagram method inside cakes there are lamps and inside lamps there are bags.
So, according to it only statement 1 follows.
So, according to it only statement 1 follows.

Cake is a pool.
But all bags are part of the pool.
All lamps are also part of the pool.
So the answer is EITHER.
But all bags are part of the pool.
All lamps are also part of the pool.

Cake is the pool, could be composed of bags and lamps only or more.
All bags are part of the pool.
All lamps are also part of the pool.
If some lamp are bags, it makes the second statement invalid and.
If no lamp is a bag, making statement one invalid.
So only one can be the answer, so either.
All bags are part of the pool.
All lamps are also part of the pool.
If some lamp are bags, it makes the second statement invalid and.
If no lamp is a bag, making statement one invalid.
So only one can be the answer, so either.

Positive questions could result in only positive conclusions. Hence the answer is A.

Middle term is not distributed once so no conclusion can be derived.

I think as the middle term is not used in any of the premises conclusion cannot be made. Anyone please clarify my doubt?

The answer should be D as some lamps are bags and all lamps can also be bags. So here lies the confusion. So the conclusion can be challenged and thus it is D none follows.
