Task: Class Definition Understanding (ontology: Arts_Media_Entertainment/CIDOC_CRM)

Which of the following definitions best describes 'E70 Thing'?

A. Scope note:
This class comprises discrete, identifiable human-made items that are documented as single units. 
These items are either intellectual products or human-made physical things, and are characterized by relative stability. They may, for instance, have a solid physical form, an electronic encoding, or they may be logical concepts or structures.

Examples:
- Beethoven’s 5(th) Symphony (E73) (Lockwood, 2015)
- Michelangelo’s David (E22) (Paoletti and Bagemihl, 2015)
- Einstein’s Theory of General Relativity (E89) (Hartle, 2003)
- the taxon ‘Fringilla coelebs Linnaeus,1758’ (E55) (Sinkevicius and Narusevicius, 2002)

In First Order Logic:
- E71(x) ⇒ E70(x)
B. Scope note:
This class comprises those material or immaterial items to which instances of E30 Right, such as the right of ownership or use, can be applied. 
This is generally true for all instances of E18 Physical Thing. In the case of instances of E28 Conceptual Object, however, the identity of an instance of E28 Conceptual Object or the method of its use may be too ambiguous to reliably establish instances of E30 Right, as in the case of taxa and inspirations. Ownership of corporations is currently regarded as out of scope of the CIDOC CRM.

Examples:
- the Cullinan diamond (E19) (Scarratt and Shor, 2006)
- definition of the CIDOC Conceptual Reference Model Version 5.0.4 (E73) (ISO 21127: 2014)

In First Order Logic:
- E72(x) ⇒ E70(x)
C. Scope note:
This general class comprises discrete, identifiable, instances of E77 Persistent Item that are documented as single units, that either consist of matter or depend on being carried by matter and are characterized by relative stability. 
They may be intellectual products or physical things. They may, for instance, have a solid physical form, an electronic encoding, or they may be a logical concept or structure.

Examples:
- my photograph collection (E78) (fictitious)
- the bottle of milk in my refrigerator (E22) (fictitious)
- the Riss A1 plan of the Straßburger Münster (French: Cathédrale Notre-Dame de Strasbourg) (E29) (Liess, R., 1985)
- the the concept on the top of Otto Hahn’s desk (E19)
- the form of the no-smoking sign (E36)
- the cave of Dirou, Mani, Greece (E26) (Psimenos, 2005)

In First Order Logic:
- E70(x) ⇒ E77(x)
D. Scope note:
This class comprises people, either individually or in groups, who have the potential to perform intentional actions of kinds for which they can be held responsible.

Examples:
- London and Continental Railways (E74)
- the Governor of the Bank of England in 1975 (E21)
- Sir Ian McKellen (E21) (Gibson, 1986)

In First Order Logic:
- E39(x) ⇒ E77(x)
