Assumptions and Unstated Implications
Identify what an argument relies on without confusing a necessary bridge with a merely helpful or compatible idea.
How to prepare for the LNAT
Practise exact passage reasoning rather than subject recall, then build a repeatable 40-minute process for choosing, planning, writing and reviewing one essay.
Core concepts
Concept 1
An assumption is an unstated claim the reasoning needs or takes for granted.
Exam cue: Locate the gap between reason and conclusion.
Concept 2
An implication is supported by the passage even though it is not stated in the same words.
Exam cue: Negate a candidate assumption and test the effect on the reasoning.
Concept 3
A necessary assumption can be tested by asking whether its denial damages the argument.
Exam cue: Demand stronger textual support when the stem asks what must follow.
Risk pitfalls and guardrails
Choosing an idea that strengthens the argument but is not required.
Guardrail: Do not import outside knowledge into Section A or substitute fluent assertion for supported reasoning in Section B.
Inferring the converse of a stated relationship.
Guardrail: Do not import outside knowledge into Section A or substitute fluent assertion for supported reasoning in Section B.
Treating what could be true as what must be true.
Guardrail: Do not import outside knowledge into Section A or substitute fluent assertion for supported reasoning in Section B.
Memory anchors
Bridge the Gap
An assumption connects the stated reason to the conclusion.
Negation Test
If denying a claim seriously weakens the reasoning, it may be necessary.
Must Versus May
Must requires entailment; may requires only compatibility.
No Converse
A relationship does not automatically work in reverse.
Unstated but Supported
An implication needs textual support even when not expressed verbatim.
Helpful Is Not Required
A strengthening statement may still be unnecessary to the argument.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
