Directions to Solve

In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

Give answer:

Statements: Some dedicated souls are angels. All social workers are angels.

Conclusions:

  1. Some dedicated souls are social workers.
  2. Some social workers are dedicated souls.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Answer: Option
Explanation:
The first premise is an I type proposition. So, the middle term 'angels' forming the predicate is not distributed. The second premise is an A type proposition. So, the middle term 'angels' forming the predicate is not distributed. Since the middle term is not distributed even once in the premises, no definite conclusion follows.

I am not able to understand the explanation kindly explain it simply by venn diagram.

See the middle term is not distributed in the second premise so both the conclusions won't follow.

The explanation is true but how can I know if the middle term is distributed or not?
