Question
Statement: 'Use our coaching, and you will clear the exam in your first attempt.'
Assumptions: I. People want to clear the exam in the first attempt. II. This coaching is the only way to clear the exam.
Which assumption is implicit?
Options
- Only I
- Only II
- Both
- Neither
Show the answer and the worked solution
Correct answer: A. Only I
Worked solution
- The advertisement only appeals if a first-attempt pass is desirable, so assumption I is implicit.
- Claiming it is the only way is far stronger than the statement needs; II is not implicit.
Answer: Only I.
The idea
An implicit assumption must be necessary for the statement to hold, not merely consistent with it. Reject anything containing 'only', 'always' or 'never' unless the statement says so.
Shortcut. Negate each: if nobody wanted a first-attempt pass the advert would fall flat, so I is needed; if other routes exist the advert still stands, so II is not.
Common trap. "Both" — accepting II because the advert sounds exclusive; it promises success, not that it is the only way.
