Question #1
Statement:
All employees of this company are highly educated.
Conclusions:
I. The company only hires individuals with advanced degrees.
II. An uneducated person cannot be an employee of this company.
Which conclusion(s) logically follow?
A. Only conclusion I follows
B. Neither I nor II follows
C. Both I and II follow
D. Only conclusion II follows

Correct Answer: Option D


Explanation:
The statement says all current employees are highly educated, which implies an uneducated person is not among them (Conclusion II follows). However, 'highly educated' does not necessarily mean 'advanced degrees' (Ph.D., Master's, etc.), so Conclusion I is an over-assumption.

A. Only conclusion II follows
B. Only conclusion I follows

Both conclusions follow if we interpret 'list of selected candidates' as the list of eligible applicants. Those who have appeared for final year and those with a second class Master's are both eligible to apply, hence they will be in the eligible list.
