Question

Statements: No gentleman is poor. All gentlemen are rich.
Conclusions:
I. All heavy fishes are grey in colour.
II. All light fishes are not grey in colour.

• 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

Answer: (A)

Only conclusion I follows

Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, it follows that 'Some heavy things are grey in colour'. I is a cumulative result of this conclusion and the first premise. Thus, only I holds.
