Question

Difficulty: MediumMust Be True / Most Strongly Supported

The Antiquarian Document Restoration Society enforces the following conservation protocols for illuminated manuscripts:

• Every fourteenth-century parchment manuscript undergoing aqueous pigment stabilization must first receive an infrared reflectography assessment.
• No document that receives an infrared reflectography assessment is approved for ultrasonic surface cleaning unless it has also been certified as having stable organic binders.
• The manuscript Codex Veridicus is a fourteenth-century parchment manuscript treated at the Guild Workshop, where it underwent aqueous pigment stabilization and was approved for ultrasonic surface cleaning.

Statement: Codex Veridicus was certified as having stable organic binders.

Answer: Answer

Answer

True
The stimulus provides sufficient premises to prove the claim with certainty. Codex Veridicus meets the exact conditions that mandate an infrared reflectography assessment, and because it was subsequently approved for ultrasonic surface cleaning, it was required by the protocol to possess certification for stable organic binders.

Step-by-Step Solution

1
Formalize the conditional premises stated in the conservation protocol.
Rule 1: (14th-century parchment AND aqueous stabilization) → infrared reflectography assessment. Rule 2: (Infrared reflectography assessment AND approved for ultrasonic cleaning) → certified stable organic binders.
Translating rules into strict logical relations allows for step-by-step deductive chaining without unwarranted assumptions.
2
Apply the factual details regarding Codex Veridicus to Rule 1.
Codex Veridicus meets both conditions for Rule 1 (it is a 14th-century parchment manuscript and underwent aqueous stabilization), so it definitely received an infrared reflectography assessment.
Modus ponens on Rule 1 establishes that Codex Veridicus received the infrared reflectography assessment.
3
Combine the result from Step 2 with the second factual premise to apply Rule 2.
Codex Veridicus received an infrared reflectography assessment AND was approved for ultrasonic surface cleaning. By Rule 2, it necessarily follows that Codex Veridicus was certified as having stable organic binders.
Applying the conjunction of the two conditions to Rule 2 strictly yields the necessary requirement of certification.
