Statement-Based Reasoning: Conclusions, Assumptions and Arguments

1. Identify what the question is testing#

Statement-based reasoning asks you to evaluate what follows from information, what an argument takes for granted, whether evidence supports a claim, or what action addresses a problem. These are different tasks. A sensible suggestion is not automatically a necessary conclusion; a necessary assumption is not automatically sufficient to prove a plan will succeed.

For deduction questions, treat the supplied premises as true and do not add outside facts. For practical arguments, judge relevance, feasibility and the stated objective. The situations in this chapter are hypothetical. They are reasoning exercises, not claims about actual institutions.

2. Separate premise, conclusion and assumption#

A premise is the information given as a reason. A conclusion is the claim the argument supports. An assumption is an unstated link needed to connect the premise to the conclusion or to make the proposed mechanism work.

Example: “We will publish notices only on a portal, so every student will be able to receive them.” The proposed action is portal-only publication; the intended result is universal access to notices. A necessary bridge is that every student has a usable way to access the portal. It is not necessary that everyone likes the portal’s colour.

That bridge alone does not guarantee success: notices must also be uploaded correctly and made available on time. A condition can be necessary without being sufficient.

3. Statement–conclusion: necessity, not plausibility#

A conclusion follows only if it is true in every situation consistent with the statements. To show that it does not necessarily follow, give one situation where all premises are true but the conclusion is false. This is a counterexample.

“All registered members have a card. Arun is a registered member.” Therefore Arun has a card. But “Arun has a card” by itself does not prove he is registered: the premises did not say only registered members can have cards.

“Some members are runners” guarantees at least one member who runs, not that all members run. “All A are B” does not by itself assert that A exist under the modern logical convention. Read the convention if an exam uses a different one; do not silently turn a universal claim into an existence claim.

4. Conditional rules: if, only if and unless#

“If P, then Q” means P is sufficient for Q and Q is necessary for P. Two valid deductions are:

• P → Q and P, therefore Q.
• P → Q and not Q, therefore not P.

Two invalid shortcuts are Q therefore P, and not P therefore not Q. Q may happen through another route. A condition failing does not prove its outcome cannot happen otherwise.

“P only if Q” also means P → Q. “P if Q” means Q → P. “P if and only if Q” includes both directions. “P unless Q”, under the ordinary inclusive logical reading, means if not Q then P; it does not automatically prohibit both P and Q. Respect any explicit definition in the question.

Worked example: if a form is complete, a ticket is issued. No ticket was issued. The form cannot have been complete under that rule. If a ticket was issued, however, the form’s completeness is not established unless the reverse rule is also supplied.

5. And, or, not and quantifiers#

“P and Q” needs both. Inclusive “P or Q” needs at least one and permits both. “Either P or Q, but not both” needs exactly one. “Not both” rules out their simultaneous truth but allows both to be false.

The negation of “P and Q” is “not P or not Q”. The negation of “P or Q” is “not P and not Q”. The negation of “all members attended” is “at least one member did not attend”, not “no member attended”. The negation of “some members attended” is “no member attended”.

Words such as all, some, only, never, always and at least affect the logical strength. “Many” is not “all”; “may” is not “must”. Keep the same population and time period when comparing statements.

6. Necessary assumptions and the negation test#

Ask: if this proposed assumption were false, would the stated reasoning lose an essential link? If yes, it may be necessary. If the plan could still work through its stated mechanism without the assumption, it is not required.

A library proposes barcode checkout using existing labels. The scanner must be able to read those labels. Negating that condition breaks the proposed mechanism. “The plan is the cheapest conceivable option” is not necessary unless the goal specifically requires absolute minimum cost.

Negate precisely. Negating “every student can access the portal” means “at least one student cannot”, not “no student can”. Negating “some users benefit” means “none benefit”. The test identifies a required link; it does not prove the whole argument sound or make the assumption a known fact.

7. Strong and weak arguments#

A strong argument directly addresses the question and supplies a relevant reason with a credible connection to the objective. A weak one may be irrelevant, circular, unsupported, excessively absolute or based only on popularity. A long argument is not necessarily stronger than a short one.

If a proposal aims to reduce checkout time, a representative trial comparing time and errors under similar loads is relevant. A celebrity liking its name is not evidence of speed. A trial using only the easiest transactions may be less representative than it appears.

Judge the argument given, not whether you personally favour the proposal. An emotionally attractive claim can still lack evidence. Authority may be relevant when the expertise and supporting evidence fit the issue; a famous name alone is not proof.

8. Strengthening and weakening#

A strengthening statement increases support for the conclusion; it need not prove it. A weakening statement reduces support; it need not establish that the conclusion is false. When the question says to treat a new finding as true, evaluate its effect rather than challenging its truth.

For a shared calendar intended to reduce conflicts, evidence that users update it and conflict rates fall under comparable conditions supports the mechanism. Evidence that users never enter unavailable periods undermines it. Changing the calendar’s colour has little bearing on scheduling accuracy.

Look for the missing bridge. Does the evidence test the plan’s mechanism, sample, comparison group or predicted outcome? Avoid choosing evidence that repeats the conclusion in different words without adding support.

9. Cause and effect: avoid the automatic leap#

Two things occurring together do not prove one caused the other. A change happening before another is necessary for many causal explanations but is not sufficient evidence of causation. Consider a third factor, reverse direction, selection bias, chance and simultaneous changes.

Example: a library installs a new checkout system and waiting time falls. Possible alternatives include fewer visitors, more staff or a quieter season. Compare similar demand and staffing, use a suitable baseline and, when feasible, a comparison group. A carefully designed trial can reduce these alternative explanations; no brief observation automatically removes them all.

If two outcomes share a common cause, do not label either as the cause of the other. Hot weather might increase both cold-drink sales and fan use. Their association alone does not show that buying drinks causes people to use fans.

10. Course of action: relevant, feasible and proportionate#

A proposed action should address the stated problem, be practical within the facts, and be proportionate to the evidence. Prefer checking the key uncertainty through a targeted pilot when full implementation depends on an untested mechanism. Avoid unrelated action, unsupported punishment or permanent cancellation merely because success is not guaranteed.

Example: before replacing printed notices with portal-only notices, audit access and test retrieval. This directly examines whether the stated universal-access goal is feasible. A rollout without checking access skips the key risk. Changing an unrelated room’s decoration does not address it.

An action question asks what to do, not what must already be true. Sometimes more than one action can be useful; choose the one that best matches the question’s timing, constraints and priority. Do not assume unlimited money or authority.

11. Measure the intended result, not an easy substitute#

If the aim is to reduce misplaced tools, measure misplaced-tool incidents relative to usage. Counting new labels measures activity, not the desired benefit. If the aim is to improve access, track successful access among the intended users, not just how many files were uploaded.

Use rates when the amount of activity changes. Ten errors out of 100 transactions differs from ten out of 1,000. Check side effects: a faster checkout with many incorrect records may not be a successful improvement. Compare a suitable baseline and inspect other changes before attributing the result to the plan alone.

12. Common reasoning errors#

Error	Why it fails
Affirming the consequent	P → Q and Q do not prove P
Denying the antecedent	P → Q and not P do not prove not Q
Hasty generalisation	A narrow sample may not represent everyone
False dilemma	Two listed options may not exhaust the possibilities
Circular reasoning	Restating the claim supplies no independent support
Personal attack	Criticising a person does not refute the reasoning
Correlation treated as causation	Association leaves alternative explanations
Necessary confused with sufficient	A required condition may not ensure success

Read the exact question before using any shortcut. “Which conclusion follows?” demands necessity; “which most strengthens?” asks for comparative support; “which first action?” asks for a relevant next step.

13. A short worked argument review#

Claim: “The training centre should add captions so participants who rely on text can follow videos.”

• Goal: access to the spoken lesson content for the specified users.
• Necessary link: captions convey the relevant content accurately enough.
• Strengthening evidence: target users understand a representative captioned version better than the same uncaptioned lesson.
• Weakening evidence: captions systematically show unrelated text.
• Relevant first step: check accuracy and test comprehension with intended users.
• Outcome measure: comprehension, not the number of decorative caption styles.

The favourable evidence supports the proposal without guaranteeing all future lessons will be successful. The assumption remains a required condition, not a fact proven merely by proposing the plan.

14. Exam routine#

Underline the task word: follows, assumes, strengthens, weakens, cause or action. Separate facts from the claim. For conclusions, seek a valid proof or counterexample. For assumptions, negate the option precisely. For arguments, test relevance and the missing link. For causal claims, search for alternatives. For actions, check feasibility and proportionality.

In this chapter’s first 20 questions, P, Q and R are explicitly defined statements. All eight truth assignments are checked to validate deductions. The remaining questions use practical scenarios and explanations; their answers are selected by the stated goal and mechanism, not by a claim that every real-world decision has one universal answer.
