Statement Assumptions
Key Concepts
| # | Concept | Explanation |
|---|---|---|
| 1 | What is an Assumption? | An unstated, logically necessary premise that must be true for the statement to hold. |
| 2 | Standard Format | Statement → Assumption → Conclusion. Assumption bridges the gap. |
| 3 | Positive vs Negative | Positive assumption supports; negative assumption contradicts. Reject negative. |
| 4 | Too Obvious | If the assumption merely repeats the statement, it is not an assumption. |
| 5 | Extreme Words | “Only”, “Always”, “Never”, “All” usually make assumptions invalid. |
| 6 | Chain Assumption | If assumption needs another assumption, it is not the correct one. |
| 7 | Venn-Trick | Draw a quick Venn/arrow diagram to visualise scope & direction. |
| 8 | 3-Step Elimination | 1. Reject contradicting. 2. Reject obvious. 3. Pick the must-be-true. |

Quick Revision
| Point | Detail |
|---|---|
| 1 | Assumption = unstated must-be-true premise. |
| 2 | If assumption is explicit in statement → reject. |
| 3 | Negative assumption → always reject. |
| 4 | “Only” in statement ⇒ reverse is invalid; “only” in assumption ⇒ likely invalid. |
| 5 | Chain assumption (assumption needs another assumption) → invalid. |
| 6 | Appeal/Advisory ⇒ assume desire/need exists. |
| 7 | Warning ⇒ assume threat exists. |
| 8 | Remedy ⇒ assume problem exists & remedy works. |
| 9 | Technology ⇒ assume feasibility, not user ownership. |
| 10 | 3-step elimination: Contradictory → Obvious → Must-be-true; saves 20 s per Q. |
