Analyze the natural language arguments below. Match each argument to its corresponding formal symbolic conditional skeleton.
- If a species is considered invasive, it threatens local biodiversity. Any species that threatens local biodiversity is subject to removal. Therefore, if a species is considered invasive, it is subject to removal.X → Y; Y → Z; ∴ X → Z (Valid Chain)
- An applicant will be approved for the advanced grant only if they have published peer-reviewed research. Dr. Aris has not published peer-reviewed research. Consequently, Dr. Aris will not be approved for the advanced grant.X → Y; ~Y; ∴ ~X (Valid Contrapositive)
- A robust marketing campaign is required for a startup to achieve profitability. The startup TechNova recently launched a robust marketing campaign. It follows that TechNova will achieve profitability.X → Y; Y; ∴ X (Flawed Reversal)
- Provided that a contract includes a non-compete clause, it is legally binding. The new employment contract does not include a non-compete clause. Thus, the new employment contract is not legally binding.X → Y; ~X; ∴ ~Y (Flawed Negation)
Cevap
Argument 1 matches the Valid Chain; Argument 2 matches the Valid Contrapositive; Argument 3 matches the Flawed Reversal; Argument 4 matches the Flawed Negation.
Each argument translates to a specific symbolic structure based on its conditional indicators. By identifying whether a condition is sufficient ('if', 'any', 'provided that') or necessary ('only if', 'is required for'), we can diagram the argument properly and classify it as a valid deduction or a formal flaw.
