Unit quiz: Knowing, doubting, and being the same self

Check understanding, separately from reading

5 questions · 80% to pass · no timer. This quiz checks the lessons in this unit. These authored questions assess recognition and application of the taught distinctions, not professional qualification. You may review the lessons and retry. Repeat attempts reuse the question bank; a remembered answer is not proof of transfer to a new situation.

Saving a lesson records reading only. Previous lesson completions have not been converted into passing scores. You can continue reading without a pass; the assessment remains unpassed.

Question 1

A nurse believes a patient is allergic to a drug because the chart says so; the chart is accurate. In fact the chart was copied from a different patient with the same surname, and the real patient also happens to be allergic. Best evaluation?The belief is true and justified, but the warrant points at another person, so the truth is connected to the evidence only accidentallyBecause the nurse’s belief matches reality, it is knowledge regardless of how the evidence was obtained

Question 2

A student defends her reading of a novel by showing that every chapter interpretation is consistent with every other and that the whole is remarkably unified, with no external checking.

What is the classmate pressing?The regress problem, that each chapter interpretation needs an infinite chain of further interpretationsThe coherentist’s input and isolation problem, that a self-consistent network may fail to connect to independent evidence

Question 3

Which diagnosis fits best?The challenge is only compelling if no independent standard is available; forensic evidence can ordinarily be tested, so the relevant alternatives can be ruled outThe challenge is decisive because any possibility at all defeats a claim to knowledge

Question 4

A surgeon says a patient with severe irreversible amnesia and a wholly changed personality is nonetheless the same person who signed a research consent, while a colleague says that person no longer exists. What is the disagreement really about?Whether memories in such cases are ever reliable enough to be admitted as clinical evidenceWhich criterion of personal identity governs, psychological continuity or the continuity of the living organism

Question 5

An employee says she acted freely because she decided to sign, though her contract left no alternative and refusal would end her career. Which pair of questions must be separated to assess her claim?Whether she could have done otherwise and whether the act originated in her own will rather than in duressWhether the outcome was predictable and whether the employer had accurate information about the contract
