Tips to Solve Syllogism Possibility Case Questions
Hello Friends,
We have given the Important Concepts and Tips to Solve Syllogism Questions (Possibility Case). Candidates those who are preparing for the examination can use this.
Syllogism – Possibility Case Type Questions:
- In these types of questions some statements will be given followed by some conclusions that can be verified from the given statements
- We should ignore the actual meaning of the terms
- These questions can be solved by using Venn diagrams
- When there is no exact conclusion for the given statements then possibility case arises
- If the conclusion is FALSE in one Venn diagram and TRUE in another diagram, then the conclusion is deduced as PARTIALLY TRUE
- PARTIALLY TRUE = TRUE
Example Question:
Directions
Select answer (1) if only conclusion I follow
Select answer (2) if only conclusion II follow
Select answer (3) if either conclusion I or II follows
Select answer (4) if neither conclusion I nor II follows
Select answer (5) if both conclusion I and II follows
Statements
Some plants are animals.
All animals are trees.
Conclusion
- All animals being plants is a possibility
- All plants being trees is a possibility
SOLUTION:
Consider Statement 1 – Some plants are animals
The Venn diagram of this statement is as follows
Similarly the Venn diagram for Statement 2 – All animals are trees is as follows
Now both Statements I and II has a common term animals, so the overall Venn diagram can be drawn as follows
Conclusion I: All animals being plants is a possibility
As per Fig.1, the conclusion I is FALSE (only some animals are plants)
As per Fig.2, the conclusion I is FALSE (here also only some animals are plants)
As per Fig.3, the conclusion I is TRUE (all animals are plants)
Hence the Conclusion I is PARTIALLY TRUE which is considered as TRUE
Therefore Conclusion I is TRUE
Similarly, Conclusion II: All plants being trees is a possibility is considered
As per Fig.1, Conclusion II is FALSE (only some plants are trees)
As per Fig.2, Conclusion II is TRUE (all plants are trees)
As per Fig.3, Conclusion II is FALSE (only some plants are trees)
Hence the Conclusion II is PARTIALLY TRUE which is considered as TRUE
Therefore Conclusion II is TRUE
Therefore the Answer will be (5), both Conclusion I and II follows
