23 of 50 cards from the Verbal Reasoning and Critical Thinking (Section A) deck — real questions with worked answers.

1. In argument analysis, what is a 'premise'?

   A premise is a statement offered as a reason or evidence to support a conclusion. It is one of the building blocks an arguer uses to persuade you that the conclusion is true.

2. In argument analysis, what is a 'conclusion'?

   The conclusion is the main claim an argument is trying to establish — the point the premises are meant to support. It is what the author wants you to accept as true.

3. What is the difference between an argument and a mere assertion?

   An argument supports a conclusion with at least one reason (premise). An assertion simply states a claim as true without offering any supporting reasons.

4. How does description differ from argument?

   Description reports facts or states of affairs without trying to persuade you of a conclusion. An argument uses reasons to drive you toward accepting a contestable claim. Description tells you what is; argument tells you what to believe and why.

5. Name common 'conclusion indicator' words that signal the main claim of an argument.

   Therefore, thus, hence, so, consequently, it follows that, which shows that, we can conclude that.

6. Name common 'premise indicator' words that signal a supporting reason.

   Because, since, for, given that, as, owing to the fact that, on the grounds that.

7. What is an 'unstated assumption' (suppressed premise) in an argument?

   An unstated assumption is a premise the argument needs to be true in order for its conclusion to follow, but which the author has left implicit rather than stating openly.

8. What is the 'negation test' for identifying a necessary assumption?

   Negate the candidate assumption. If the negation makes the argument fall apart (the conclusion can no longer be supported), the statement is a necessary assumption. If the argument survives the negation, it is not required.

9. What does it mean to evaluate the 'strength' of reasoning in an argument?

   It means judging how well the premises actually support the conclusion — whether the inference is logically tight, whether the evidence is sufficient and relevant, and whether plausible objections have been addressed.

10. What is a 'valid inference' from a text in LNAT terms?

    A valid inference is a conclusion that must be true (or is strongly licensed) given only the information stated in the passage, without adding outside facts or assumptions.

11. What is 'over-inference' and why must it be avoided in LNAT reasoning?

    Over-inference is drawing a conclusion that goes further than the text actually supports. It must be avoided because the correct answer must be grounded strictly in what the passage states or directly entails, not in what is merely plausible.

12. Why should you avoid bringing in outside knowledge when answering LNAT comprehension questions?

    LNAT tests reasoning from the given text. Outside knowledge — even if factually true — can lead you to pick answers the passage does not support, so inferences must rely only on the information provided.

13. Define a 'necessary condition'.

    A necessary condition is one that must be present for an outcome to occur; without it, the outcome cannot happen. If $A$ is necessary for $B$, then $B \to A$ (B cannot occur without A).

14. Define a 'sufficient condition'.

    A sufficient condition is one whose presence guarantees the outcome. If $A$ is sufficient for $B$, then $A \to B$ (whenever A holds, B holds).

15. State the logical formulas linking necessary and sufficient conditions.

    "$A$ is sufficient for $B$" means $A \to B$. "$A$ is necessary for $B$" means $B \to A$. If $A$ is both necessary and sufficient for $B$, then $A \leftrightarrow B$.

16. Give an example distinguishing a necessary from a sufficient condition.

    Being a mammal is necessary but not sufficient for being a dog (all dogs are mammals, but not all mammals are dogs). Being a dog is sufficient but not necessary for being a mammal.

17. What is the key distinction between correlation and causation?

    Correlation means two variables vary together; causation means one variable actually produces a change in the other. Correlation alone does not establish causation — the link may be coincidental, reversed, or due to a third factor.

18. What is a 'confounding variable' (third-variable problem) in causal reasoning?

    A confounding variable is an unmeasured third factor that independently influences both correlated variables, creating an apparent causal link between them where none directly exists.

19. What is 'reverse causation'?

    Reverse causation is the error of assuming that $A$ causes $B$ when in fact $B$ causes $A$ — the direction of the causal arrow is mistaken.

20. Distinguish a cause from a consequence.

    A cause is the factor that brings about an effect; a consequence is the effect or result that follows from it. Confusing them reverses the logical/temporal order of events.

21. What is the 'post hoc ergo propter hoc' fallacy?

    "After this, therefore because of this" — the error of assuming that because event B followed event A, A must have caused B. Temporal sequence is mistaken for causation.

22. What is the 'ad hominem' fallacy?

    Attacking the person making an argument — their character, motives or circumstances — instead of engaging with the substance of the argument itself.

23. What is the 'straw man' fallacy?

    Misrepresenting, exaggerating or oversimplifying an opponent's position so that the distorted version is easier to attack, then refuting that distortion instead of the real argument.
