The statements below are followed by two conclusions labelled I and II. Assuming that the information in the statements is true, even if it appears at variance with generally established facts, decide which conclusion(s) logically and definitely follow(s) from the information given in the statements.
Statements:
1.) All pens are frogs.
2.) Some crows are frogs.
Conclusions:
I. No pen is a crow.
II. Some pens are crows.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Either conclusion I or conclusion II follows.
The least possible Venn diagram is shown below:
Conclusions:
I. No pen is a crow: False (It is possible but not definite, as no direct relationship between the two is given).
II. Some pens are crows: False (It is possible but not definite, as no direct relationship between the two is given).
The two conclusions form a complementary pair.
Hence, the correct answer is Either Conclusion I or II follows
