Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
No atom is a molecule.
No molecule is an element.
Conclusions:
I. It is possible for some atoms to be elements.
II. Some elements are molecules.
Option 1: Only conclusion I follows
Option 2: Both conclusions I and II follow
Option 3: Only conclusion II follows
Option 4: Neither conclusion I nor II follows
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram, according to the given statements is as follows –
Let's analyze the conclusions –
Conclusion (I):
It is possible for some atoms to be elements –
It is a possibility that the circles representing atoms and elements overlap. But this is not definite. Thus, this conclusion follows.
Conclusion (II):
Some elements are molecules –
From the Venn diagram, it is evident that there is a negative relation between elements and molecules. Thus, this conclusion does not follow.
So, the only conclusion I follows. Hence, the first option is correct.
