Archivist: Any parchment document treated with nano-cellulose spray creates an airtight molecular barrier. Furthermore, any document that possesses an airtight molecular barrier resists microbial ink erosion. Since the fourteenth-century guild charter was treated with nano-cellulose spray, it is certain to be approved for permanent display in the main rotunda.
The archivist's conclusion follows logically if which one of the following is assumed?
- AAny document that is approved for permanent display in the main rotunda possesses an airtight molecular barrier.
- BA document cannot be approved for permanent display in the main rotunda unless it was treated with nano-cellulose spray.
- Every parchment document that resists microbial ink erosion is approved for permanent display in the main rotunda.Answer
- DAny document treated with nano-cellulose spray resists microbial ink erosion.
- ENo document that fails to resist microbial ink erosion has been treated with nano-cellulose spray.
Answer
Every parchment document that resists microbial ink erosion is approved for permanent display in the main rotunda.
The argument establishes that the charter was treated with nano-cellulose spray, which guarantees an airtight molecular barrier, which in turn guarantees that it resists microbial ink erosion. The conclusion asserts that the charter will be approved for permanent display. The statement establishing that every parchment document that resists microbial ink erosion is approved for permanent display creates a complete, unbroken deductive chain: Charter → Nano-cellulose → Airtight Barrier → Resists Erosion → Approved for Display.
