Reasoning & Problem Solving flashcards for ParaProfessional / Clerical civil service tests (state & local)

22 of 52 cards from the Reasoning & Problem Solving deck — real questions with worked answers.

1. What is deductive reasoning?

   Reasoning from general premises to a specific, logically certain conclusion. If the premises are true and the form is valid, the conclusion MUST be true (top-down reasoning).

2. What is inductive reasoning?

   Reasoning from specific observations or examples to a general conclusion. The conclusion is probable, not guaranteed—it can be strong or weak but never certain (bottom-up reasoning).

3. In a valid deductive argument, can the conclusion be false if all premises are true?

   No. Validity means that IF the premises are true, the conclusion cannot possibly be false. A valid argument with true premises is called 'sound.'

4. What is the key difference between deductive and inductive conclusions in terms of certainty?

   Deductive conclusions are certain (guaranteed by the premises); inductive conclusions are only probable (supported but not guaranteed).

5. What is a syllogism?

   A deductive argument with two premises (a major and a minor) and a conclusion, e.g., 'All A are B; all B are C; therefore all A are C.'

6. Given 'All clerks must file reports' and 'Maria is a clerk,' what valid deductive conclusion follows?

   Maria must file reports. (The specific case inherits the rule that applies to all members of the group.)

7. When drawing a valid conclusion from given statements on a civil service test, what must you rely on?

   Only the information stated in the passage—not outside knowledge or assumptions. A conclusion is valid only if it MUST be true based solely on the given statements.

8. From 'No part-time employees receive benefits' and 'Sam receives benefits,' what must be true?

   Sam is not a part-time employee. (This is valid by contraposition / denying the consequent.)

9. From 'Some applicants passed the exam,' can you conclude 'Some applicants failed the exam'?

   No. 'Some passed' does not tell you whether any failed; it is invalid to conclude anything about those who did not pass.

10. What does the logical term 'all' guarantee versus the term 'some'?

    'All' means every member without exception (universal); 'some' means at least one, possibly all, but not necessarily more than one. 'Some' never guarantees 'all' or 'none.'

11. What is the valid contrapositive of 'If P then Q'?

    'If not Q then not P.' The contrapositive is logically equivalent to the original conditional and is always valid.

12. What is an assumption in an argument?

    An unstated premise the argument takes for granted and needs in order for its conclusion to hold. To find it, ask: 'What must be true for this conclusion to follow?'

13. What is the logical fallacy of 'affirming the consequent'?

    Invalidly concluding P from 'If P then Q' and 'Q is true.' Example: 'If it rains, the street is wet; the street is wet; therefore it rained'—invalid, since other causes could wet the street.

14. What is the logical fallacy of 'denying the antecedent'?

    Invalidly concluding 'not Q' from 'If P then Q' and 'not P.' Example: 'If it rains the street is wet; it did not rain; therefore the street is not wet'—invalid.

15. What is a hasty generalization?

    An inductive error: drawing a broad conclusion from too few or unrepresentative examples (e.g., judging all employees by one person's behavior).

16. What is a circular argument (begging the question)?

    A reasoning error in which the conclusion is assumed within the premises, so the argument proves nothing new (e.g., 'It's reliable because it works correctly').

17. What is a false dilemma (either/or fallacy)?

    Presenting only two options as if they were the only possibilities when other alternatives actually exist.

18. What does post hoc ergo propter hoc mean as a reasoning error?

    'After this, therefore because of this'—wrongly assuming that because event B followed event A, A caused B. Sequence alone does not prove causation.

19. In cause-and-effect reasoning, why does correlation not prove causation?

    Two things can vary together due to coincidence, a reversed cause, or a hidden third (confounding) factor that causes both. Correlation is necessary evidence but not sufficient to establish cause.

20. What is a confounding (lurking) variable in a cause-and-effect relationship?

    A hidden third factor that influences both the supposed cause and the supposed effect, creating a misleading apparent link between them.

21. In a cause-and-effect chain, what distinguishes the immediate cause from the root cause?

    The immediate (proximate) cause is the event directly preceding the effect; the root (ultimate) cause is the underlying origin that set the chain in motion.

22. What is reverse causation as a reasoning error?

    Concluding A causes B when in fact B causes A (the direction of the cause-effect relationship is backward).
