Statement: The employees association has appealed to the Managers of Company Z to introduce written examinations for clerical cadre recruitment to prevent selection of incompetent persons.
Assumptions:
1. So far the Company Z used to select candidates without conducting a written examination.
2. A written examination can help to identify competent persons.
3. At higher level, written examination may not be of much use.
Answer: A
An appeal has been made to 'introduce' written examination. This means that so far written examination was not conducted. So, I is implicit. II follows directly from the statement and so it is implicit. However, nothing can be deduced about the mode of selection at higher level. So, III is not implicit.
