In the following question below are given three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: I. At least some gun are black. II. Only black is night. III. Some sharp are gun. Conclusions: I. All sharp being black is a possibility. II. All black being gun is a possibility. III. All gun being sharp is a possibility.?

Option 3 : Both I and III follow

Consider the following least possible Venn diagram,

Conclusions:

I. All sharp being black is a possibility → True, possibility is true as shown below.

II. All black being gun is a possibility → False (this possibility cannot be true because If all black are gun then all night will be gun which contradicts the statement only black is night).

III. All gun being sharp is a possibility → True as this possibility can be true.

Hence, both conclusions I and III follow.
