What is the argument?
Separate a claim, its support, and the conclusion it is meant to support.
Go to practice ↓A question to keep in mind
A result sounds convincing. Which sentence is actually doing the work?
A statement says something that can be true or false, once its context is fixed. A question or command does not normally assert such a claim. An argument is a set of statements offered as reasons for another statement. It is not just a disagreement.
Premises are the offered reasons; the conclusion is what those reasons are meant to establish. These are roles, not positions in a paragraph. The same sentence can be a conclusion in one argument and a premise in the next.
First reconstruct the speaker's inference charitably, then assess it. Words such as 'so' and 'because' are clues, not guarantees. An explanation of an accepted event and an argument that the event occurred can use similar language; ask what is being disputed.
Work through an example
- Every registered participant may enter. Lin is registered. Therefore Lin may enter.
- Premise 1: the admission rule. Premise 2: Lin meets that rule. Conclusion: Lin may enter.
- Whether the rule is actually enforced is a separate question. Identifying a premise does not endorse it.

- All archived files have a checksum. → Premise
- File A is archived. → Premise
- So file A has a checksum. → Conclusion
- The team discussed this on Tuesday. → Background
The rule and the fact about A support the checksum conclusion. The meeting date contributes no support in this reconstruction.
Which is a statement, with its context fixed?

The test failed at noon.
Statements need not be true to be statements. 'The test failed' is a statement even if the test passed.
'Use model B: it had fewer errors in our test.' What is the best first reconstruction?
Read solution · does not award completion
Fewer errors is offered as a reason to choose B.
Reconstruction comes before agreement. Next ask about the test's relevance and the costs of switching.

How do I retain independent judgment when using AI here?
Keep your own answer before consulting an AI candidate. Check sources, calculations, inference and conditions; explain adoption or rejection. Then solve a new-context task independently and apply the checks to this lesson.
