Inference and Assumption Questions
Inference and Assumption Questions
Inference and assumption questions are the hardest part of RC because the answer is never printed in the passage — you must reason from what is written to what logically follows. This is where most candidates lose marks, either by choosing an option that is directly stated (and therefore not an inference) or one that goes far beyond the passage. The safe rule is to stay one small, defensible step from the text.
Implied Versus Directly Stated
An inference is something the passage strongly suggests without saying outright, so an option that copies a line word for word is not the inference — it is a detail. Equally, an inference must be supported by the passage, not merely consistent with the world at large. The correct inference is the quiet conclusion the author would have to accept given what they wrote, no more and no less. A handy check is to ask whether the author, shown your chosen option, would nod and say 'yes, that follows' rather than 'I never said that' — only the first kind of option is a real inference.
The One-Step Rule
Take exactly one logical step beyond the text and stop. If a passage says a bank's app cut branch visits sharply, you may infer customers found the app convenient; you may not infer the bank will close its branches, which is several steps away. Reject any option that needs a chain of extra assumptions, because the exam rewards the nearest safe conclusion, never the boldest one you can imagine. Boldness is punished here; timid, tightly-anchored reasoning is what scores.
Spotting the Out-of-Scope Option
The commonest wrong answer is out of scope: it introduces a country, a comparison, a cause or a future the passage never raised. Train yourself to ask 'did the passage actually mention this?' for every option. If the idea, or the information needed to support it, is simply not in the passage, the option is out of scope regardless of how sensible it sounds in real life. Real-world knowledge is a trap here, not a help: the exam deliberately writes options that are true in general but unsupported by this passage, and the disciplined reader answers only from the words on the page.
| Option feels... | Likely nature | Action |
|---|---|---|
| Copied from a line | Directly stated, not inference | Reject |
| One safe step from text | Valid inference | Likely correct |
| Needs facts not in passage | Out of scope | Reject |
Solved Example
Example: A passage says salaries were credited late because a server failed. A valid inference is that the delay was not intentional. 'The bank will change its server vendor' is out of scope, and 'salaries were credited late' merely repeats a stated fact, so neither is the inference.
✗ Choosing a real-world-true option the passage never supports | ✓ Choosing the one-step conclusion the passage's own words force
Assumption Questions and the Negative Test
An assumption is something the author must be taking for granted for their statement to hold, an unstated foundation rather than a conclusion drawn afterward. The quickest way to test a candidate assumption is the negation test: negate the option and check whether the author's argument collapses. If denying the option destroys the argument, it was a genuine assumption; if the argument survives the denial, the option was never assumed. Suppose the author argues a new online service will boost enrolment; the assumption that customers have internet access passes the test, because if they do not, the argument fails entirely. This single test cuts through the tempting but irrelevant options that make assumption questions feel harder than they really are.
Exam Pointer — SBI Clerk RC usually carries one or two inference or assumption questions, and they separate the fast scorers from the rest. Never pick an option that merely restates a line, and never pick one that needs facts the passage never gave. Stay one defensible step from the text, and use the negation test on assumption options.
60-Second Recap
- Inference is implied, never word-for-word from the passage.
- Take one safe step beyond the text and stop.
- Reject out-of-scope options the passage never raised.
- Assumptions: negate the option; if the argument fails, it was assumed.
