Statements:
1. Some musicians are singers.
2. All singers are dancers.
Conclusions:
I. Some musicians are dancers.
II. No musician is a dancer.
Which conclusion(s) logically follow?
A. Only conclusion II follows
B. Both I and II follow
C. Neither I nor II follows
D. Only conclusion I follows
Answer: Option D
Solution (By JKExamLibrary)
The musicians who are singers must also be dancers because all singers are dancers. Therefore, some musicians are definitely dancers. Conclusion I is true, and Conclusion II is false.
Statements:
1. Some phones are smart.
2. No smart thing is cheap.
Conclusions:
I. Some phones are not cheap.
II. No phone is cheap.
Which conclusion(s) logically follow?
Explanation:
The phones that are smart cannot be cheap (since no smart thing is cheap). Therefore, at least some phones are definitely not cheap (Conclusion I). We don't know about the phones that are not smart, so II does not follow.
Explanation:
The proverb means practice leads to perfection, implying it's necessary. So I (practice alone may be sufficient) and II (without it, no perfection) both follow in the context of the saying.
