Statement Assumptions

Key Concepts

#ConceptExplanation
1What is an Assumption?An unstated, logically necessary premise that must be true for the statement to hold.
2Standard FormatStatement → Assumption → Conclusion. Assumption bridges the gap.
3Positive vs NegativePositive assumption supports; negative assumption contradicts. Reject negative.
4Too ObviousIf the assumption merely repeats the statement, it is not an assumption.
5Extreme Words“Only”, “Always”, “Never”, “All” usually make assumptions invalid.
6Chain AssumptionIf assumption needs another assumption, it is not the correct one.

15 Practice MCQs

  1. Statement: “Use R-Wallet, the new digital ticketing app of Railways, for hassle-free booking.” Assumption I: People want hassle-free booking.
    Assumption II: R-Wallet is faster than traditional methods.
    A. Only I implicit B. Only II implicit C. Both I & II D. Neither
    Answer: A
    Solution: The appeal is based on the desire for convenience; speed is not claimed.

    II. 8-hour shift will reduce fatigue.
    A. Only I B. Only II C. Both D. Neither
    Answer: C
    Solution: Both are necessary; if longer shifts did not cause fatigue, no need to reduce them; if 8-hour does not reduce fatigue, action is useless.

Quick Revision

PointDetail
1Assumption = unstated must-be-true premise.
2If assumption is explicit in statement → reject.
3Negative assumption → always reject.
4“Only” in statement ⇒ reverse is invalid; “only” in assumption ⇒ likely invalid.
5Chain assumption (assumption needs another assumption) → invalid.
6Appeal/Advisory ⇒ assume desire/need exists.
7Warning ⇒ assume threat exists.
8Remedy ⇒ assume problem exists & remedy works.
9Technology ⇒ assume feasibility, not user ownership.
