Statement : Most of the job appointments have a one or two year probation period. Assumption I : It is difficult to judge the abilities of the candidate completely at the time of appointment. Assumption II : People try to demonstrate their maximum potential during the probation period.

The correct answer is (C) Both Assumptions are implicit.

• Logical Principle: An assumption is an unstated premise that makes a statement valid. The statement discusses the necessity of a probation period, implying a logical rationale for evaluating performance over time.
• Step-by-step Deduction: Assumption I is implicit because the purpose of a probation period is precisely to overcome the difficulty of assessing a candidate's complete capability in a single interview or test. Assumption II is also implicit because it explains the behavioral intent of the employee during this period, reinforcing the necessity for the employer to observe the candidate under actual working conditions where the candidate tries their best.
• Result Verification: Since the statement implies both the limitation of initial evaluation (Assumption I) and the expectation of candidate performance during probation (Assumption II), both are necessary logical foundations for the policy. Therefore, options A, B, and D are incorrect.
