In the question, two statements are given, followed by two conclusions, I and II. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement I: No plastics are polymers. Statement II: Some rubbers are plastics. Conclusion I: Some polymers are rubbers. Conclusion II: All rubbers are polymers.
In the question, two statements are given, followed by two conclusions, I and II. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement I: No plastics are polymers. Statement II: Some rubbers are plastics. Conclusion I: Some polymers are rubbers. Conclusion II: All rubbers are polymers. Correct Answer Neither conclusion I nor conclusion II follows
The possible Venn diagram is as follows:
Conclusion I: Some polymers are rubbers → False (as it is not definite but possible)
Conclusion II: All rubbers are polymers → False (as it is not definite but possible)
Hence, neither conclusion I nor conclusion II follows.
