Question 21
Back to Exercise
Statements: All fishes are grey in colour. Some fishes are heavy.
Conclusions:
I. All heavy fishes are grey in colour.
II. All light fishes are not grey in colour.
- A Only conclusion I follows Correct
- B Only conclusion II follows
- C Either I or II follows
- D Neither I nor II follows
- E Both I and II follow
Correct Answer: Option A
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.
