Two statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly knownfacts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some classes are theories.
Some theories are lessons.
Conclusions:
I. All classes can never be lessons.
II. All theories being classes is a possibility.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Only conclusion II follows
The least possible venn diagram is
I. All classes can never be lessons. False (as there is no negative relation between class and lesson thus it can be true)
II. All theories being classes is a possibility. True (as there is no negative relation between class and theory thus it can be true)
Hence, Only conclusion II follows is the correct answer.
