At the Maritime History Museum, every ship model constructed prior to 1850 is housed in a climate-controlled glass display case. Furthermore, any artifact housed in a climate-controlled glass display case is inspected weekly for humidity damage. No artifact inspected weekly for humidity damage is permitted to be loaned out for traveling exhibitions.
If the statements above are true, which one of the following must also be true?
- AAny artifact at the Maritime History Museum that is inspected weekly for humidity damage is a ship model constructed prior to 1850.
- BAny ship model at the Maritime History Museum constructed after 1850 is permitted to be loaned out for traveling exhibitions.
- No ship model at the Maritime History Museum constructed prior to 1850 is permitted to be loaned out for traveling exhibitions.Cevap
- DEvery artifact at the Maritime History Museum is eventually housed in a climate-controlled glass display case.
- ETraveling exhibitions never feature artifacts that require specialized preservation techniques.
Cevap
No ship model at the Maritime History Museum constructed prior to 1850 is permitted to be loaned out for traveling exhibitions.
The correct option is derived by combining the given conditional rules into a single unbroken chain: if an artifact is a pre-1850 ship model, it must be housed in a climate-controlled case; if it is in such a case, it must receive weekly humidity inspections; and if it receives weekly humidity inspections, it is not permitted to be loaned for traveling exhibitions. Therefore, no pre-1850 ship model can be loaned for traveling exhibitions.
