To solve this logical reasoning problem, let's analyze the given statement and conclusions carefully.
Statement: Any student who follows un-ethical practices in examination disqualifies himself from examinations.
We need to determine which of the given conclusions logically follows from the provided statement.
- Conclusion I: Those who involve in un-ethical practices in examination shall be debarred.
- The statement explicitly mentions that students engaging in unethical practices will disqualify themselves. This implies that they will be prohibited from continuing, akin to being 'debarred'.
- Conclusion I is a direct consequence of the statement, therefore, it logically follows.
- Conclusion II: The examination system should be improved.
- The statement does not make any assertions about the quality or state of the examination system. It only addresses the consequences of unethical behavior.
- The suggestion for system improvement is an external recommendation and not a logical deduction from the given statement.
- Thus, Conclusion II does not follow from the statement.
Conclusion: Based on the analysis, only Conclusion I follows.
