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

Which of the following definitions best describes 'E72 Legal Object'?

A. 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)
B. Scope note:
This class comprises all persistent physical items with a relatively stable form, human-made or natural.
Depending on the existence of natural boundaries of such things, the CIDOC CRM distinguishes the instances of E19 Physical Object from instances of E26 Physical Feature, such as holes, rivers, pieces of land, etc. Most instances of E19 Physical Object can be moved (if not too heavy), whereas features are integral to the surrounding matter.
An instance of the concept occupies not only a particular geometric space at any instant of its existence, but in the course of its existence it also forms a trajectory through spacetime, which occupies a real, that is phenomenal, volume in spacetime. We include in the occupied space the space filled by the matter of the the concept and all its inner spaces, such as the interior of a box. For the purpose of more detailed descriptions of the presence of an instance of the concept in space and time it can be associated with its specific instance of E92 Spacetime Volume by the property P196 defines (is defined by). 
The CIDOC CRM is generally not concerned with amounts of matter in fluid or gaseous states, as long as they are not confined in an identifiable way for an identifiable minimal time-span.

Examples:
- the Cullinan Diamond (E19) (Scarratt and Shor, 2006)
- the cave “Ideon Andron” in Crete (E26) (Smith, 1844-49)
- the Mona Lisa (E22) (Mohen, 2006)

In First Order Logic:
- E18(x) ⇒ E72(x)
C. 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)
D. Scope note:
This class comprises events that bring into existence any instance of E77 Persistent Item. 
It may be used for temporal reasoning about things (intellectual products, physical items, groups of people, living beings) beginning to exist; it serves as a hook for both a terminus post quem and a terminus ante quem.

Examples:
- the birth of my child (E67) (fictitious)
- the birth of Snoopy, my dog (fictitious)
- the calving of the iceberg that sank the Titanic
- the construction of the Eiffel Tower (E12) (Tissandier, 1889)

In First Order Logic:
- E63(x) ⇒ E5(x)
