Read-only question overview. Answers and scoring remain inside authenticated learner attempts.

• What is the primary classification of semantic fallacies?
• If the premises are true but the conclusion does not follow, what is the primary defect?
• What causes the main error in the textbook’s example using “rational”?
• What follows from “Every human is rational; every rational being is an animal”?
• Why does sharing the predicate “encompasses events” not identify time with the sphere?
• Which pair of premises satisfies the figure-two requirement of differing quality?
• What is the core defect in begging the question?
• When does “Zayd is human because he is bashar” beg the question?
• What does “taking the accidental as the essential” mean?
• What does the passenger-in-the-ship example teach?
• Which conclusion does not follow from “Humans have hair; hair grows”?
• What requirement is violated when “the middle term is not repeated in full”?
• Which confusion exemplifies potentiality versus actuality?
• Which term shifts meaning in the silent-speaker fallacy?
• What does “alone” restrict in “Only the human laughs”?
• What is NOT established by “Only humans laugh; every laugher is an animal”?
• Which error characterizes mistaken predication?
• Why does “Every human is an animal; animal is a genus” not entail “Every human is a genus”?
• What does “laysa bi-l-ḍarūra an yakūn” mean?
• What does “bi-l-ḍarūra an lā yakūn” assert?
• How do negating absence and denying necessary presence differ?
• What must be identified when negation changes position relative to the copula?
• Why is the accidental truth of a conclusion insufficient for demonstration?
• Why isolate the conclusion before evaluating an argument?
• If premise matter is sound but form is unproductive, what follows?
• How should “All birds are fish; all fish are animals; therefore birds are animals” be assessed?
• How should an argument that uses “speaker” first potentially and then actually be repaired?
• Which statement correctly characterizes “genus” as a logical term?
• Separating the precise claim from its alleged consequence primarily prevents what error?
• An invalid inference may have an accidentally true conclusion without becoming valid.
• Potentially speaking and actually speaking must always count as the same middle term.
• Every human is an animal, and animal is a genus; therefore every human individual is a genus.
• “It need not be” and “It necessarily is not” are logically equivalent.
