Syllogism Tips and Tricks for Government Exams
Explanation (Simple case A, B & C): 
Let A, B & C are three person. A & B know each other. B & C know each other But B knows both. Now, Will A talk about C?
The answer is 'Not!, Neither Positive Nor Negative' because he doesn't know him. So conclusion C is False.
Possibility Case (Conclusion : D, E & F): 
Now Let's take a look at conclusion E.Now Suppose there is raining outside your home and someone comes to you and say there is a possibility to rain today. What would you say to him,' Mad!"The Same scenario is here By looking at diagram it clearly says that Some B are A then how could say it is 'possible' which is actually there. Hence Possibility makes it wrong or false the conclusion. So Conclusion E is wrong.
Now talk about conclusion F which says Some A are not c which we don't know but it says to let it is a 'possibility' so anything could be possible which doesn't make our statement wrong or contradict with statement. If we make it like this below:
Syllogism Tips and Tricks for Government Exams

We talk here about possibility which could be anything which especially not contradict with our statement. So F which was False in Simple Case but When we talk about the possibility is becoming true.
Let's take another example for this. Now Let There is a cloudy sky outside your home. Someone comes to you and say," There is a possibility that there might be rain today", Now you have no idea whether it rain today or not. So you might be saying ," Bro! It is possible".Now here you cannot talk about negative because in Syllogism Negative Answer will never be there.
