Every statement a person makes rests on things they did not say. When a notice reads “the canteen will close at noon on Friday”, it assumes the canteen normally opens. The sentence would be pointless otherwise. An assumption is exactly this hidden support: a claim the speaker must be taking for granted for the statement to make sense.
This question type tests whether you can see the scaffolding behind a sentence, and whether you can tell a genuine support from a conclusion, a piece of advice, or a plain restatement. Candidates who answer by opinion fail; the answer is decided by structure, not by what you believe.
Think of the statement as a table top and the assumption as the leg holding it up. Remove the leg and the table falls.
What this model omits: it does not tell you how strong or how likely an assumption is. A statement can rest on a weak assumption; the exam still credits it if the statement cannot stand without it.
The negation test. Take each option, imagine it false, and re-read the statement. If the statement stops making sense or becomes impossible, the option is an assumption. If the statement survives untouched, it is not.
Suppose the statement is “all applicants must submit the form before the deadline”. Negate the option “the deadline is known to applicants”. If nobody knows the deadline, the instruction is useless, so the statement collapses. The option is a valid assumption.
| Option kind | How to recognise it |
|---|---|
| Assumption | Hidden, required, and its negation breaks the statement |
| Conclusion | Drawn out from the statement; follows rather than supports |
| Restatement | Repeats the statement in different words, adds nothing |
| Inference | May follow from the statement, but the statement does not need it |
| Overreach | Too broad or too strong; the statement can stand without it |
Watch the wording. Words like all, only, every and never make an option too strong. A statement that says some trainees improved does not assume that all trainees can improve. The safe assumption is almost always the modest one.
Statement: “Residents should not burn leaves in the open because the smoke worsens air quality in the colony.”
Candidate assumptions: (a) smoke from burning leaves affects air quality; (b) residents burn leaves; (c) burning leaves is the only cause of poor air quality.
Option (a) is already stated in the words “the smoke worsens air quality”, so it cannot be a hidden assumption. Option (c) is too strong: the advice works even if other causes also exist. Option (b) is the credited assumption: the advice is framed as a correction of an existing practice, so it presumes that residents do burn leaves. If none did, the advisory would be addressing a problem that does not exist.
The credited assumption is (b), the modest linking claim. Notice that the conclusion, that residents should stop burning leaves, is the advice the statement delivers, not the assumption behind it.
How do you test whether an option is an assumption?
Statement: “Use the north gate; it is closer to the examination hall.” Which is assumed?
Statement: “Some students failed the mock test, so the teaching needs review.” Which option is too strong to be an assumption?
When can “none of these is assumed” be the correct answer?
Without looking back: what are the three signs of an assumption, and which words make an option too strong?
The answer: it is hidden, required, and its negation breaks the statement; overly strong options usually contain words such as all, only, or never.
Fill in the blanks from memory:
An assumption is an premise that the statement depends on. The standard test is to the option and see whether the statement collapses. An inference is drawn from the statement, while an assumption is something the statement takes for beforehand.
Statement: “The library must extend its weekend hours, because students have no quiet place to study on Sundays.” Which of these is assumed: (1) the library is the only quiet study place; (2) students need a quiet place on Sundays; (3) the library can open on Sundays?
Option (1) overreaches. The advice to extend hours still stands even if other quiet places exist; the statement never claims exclusivity. It is too strong, so it is not assumed.
Option (2) is close to a restatement. The statement says students have no quiet place on Sundays; that already says the need exists. A restatement is not a hidden assumption. Treat it as stated content rather than the credited assumption.
Option (3) survives the negation test. Negate it — the library cannot open on Sundays — and the recommendation becomes impossible to follow. The statement depends on the library being able to open, so this is the required assumption.
The pattern to carry forward: keep the modest linking option, drop the restatement and the absolute claim, and let the negation test decide.
Assumptions look backwards, at what a statement silently needs. The next lesson looks forwards, at what a set of statements forces you to accept, and how to separate a conclusion that must follow from one that merely might.
