Question

Statements: All fish are tortoise. No tortoise is a crocodile.
Conclusions:
I. No crocodile is a fish
II. No fish is a crocodile.

• A. Only conclusion I follows
• B. Only conclusion II follows
• C. Either I or II follows
• D. Neither I nor II follows
• E. Both I and II follow

Answer 1

The correct option is E Both I and II follow

Since both the premises are universal and one premise is negative, the conclusion must be universal negative. Also, the conclusion should not contain the middle term. So, II follows; I is the converse of II and thus it also holds.
