Statement: "You are hereby appointed as a programmer with a probation period of one year and your performance will be reviewed at the end of the period for confirmation." - A line in an appointment letter. Assumptions: The performance of an individual generally is not known at the time of appointment offer. Generally an individual tries to prove his worth in the probation period.

Given data

• Appointment letter: 'appointed as a programmer with a probation period of one year; performance will be reviewed at the end for confirmation.'
• Assumption I: The performance of an individual generally is not known at the time of appointment offer.
• Assumption II: Generally an individual tries to prove his worth in the probation period.

Concept/Approach

In assumption questions, an assumption is implicit if the statement makes little sense without it.

Step-by-step reasoningProbation exists to assess suitability ⇒ It presumes performance is not fully known at offer time (supports I).Stating a review for confirmation implies the individual will make an effort to demonstrate competence during probation (supports II).

Verification/Alternative

Without (I), a year-long probation/review would be redundant. Without (II), the notion of 'proving worth' during probation would be irrelevant to confirmation.

Common pitfalls

• Confusing assumptions with consequences; here both are preconditions that make the probation clause meaningful.

Final AnswerBoth I and II are implicit.
