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

Which of the following definitions best describes 'E5 Event'?

A. 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)
B. Scope note:
This class comprises distinct, delimited and coherent processes and interactions of a material nature, in cultural, social or physical systems, involving and affecting instances of E77 Persistent Item in a way characteristic of the kind of process. Typical examples are meetings, births, deaths, actions of decision taking, making or inventing things, but also more complex and extended ones such as conferences, elections, building of a castle, or battles.
While the continuous growth of a tree lacks the limits characteristic of an the concept, its germination from a seed does qualify as an the concept. Similarly, the blowing of the wind lacks the distinctness and limits of an the concept, but a hurricane, flood or earthquake would qualify as an the concept. Mental processes are considered as events, in cases where they are connected with the material externalization of their results; for example, the creation of a poem, a performance or a change of intention that becomes obvious from subsequent actions or declarations.
The effects of an instance of the concept may not lead to relevant permanent changes of properties or relations of the items involved in it, for example an unrecorded performance. Of course, in order to be documented, some kind of evidence for an the concept must exist, be it witnesses, traces or products of the the concept.
While instances of E4 Period always require some form of coherence between its constituent phenomena, in addition, the essential constituents of instances of the concept should contribute to an overall effect; for example, the statements made during a meeting and the listening of the audience.
Viewed at a coarse level of detail, an instance of the concept may appear as if it had an ‘instantaneous’ overall effect, but any process or interaction of material nature in reality have an extent in time and space. At a fine level, instances of the concept may be analysed into component phenomena and phases within a space and timeframe, and as such can be seen as a period, regardless of the size of the phenomena. The reverse is not necessarily the case: not all instances of E4 Period give rise to a noteworthy overall effect and are thus not instances of the concept.

Examples:
- the birth of Cleopatra (E67) (Pomeroy, 1984)
- the destruction of Herculaneum by volcanic eruption in 79 AD (E6) (Camardo, 2013)
- World War II (E7) (Barber, 1994)
- the Battle of Stalingrad (E7) (Hoyt, 1993)
- the Yalta Conference (E7) (Harbutt, 2010)
- my birthday celebration 28-6-1995 (E7)
- the falling of a tile from my roof last Sunday (fictitious)
- the CIDOC conference 2003 (E7)

In First Order Logic:
- E5(x) ⇒ E4(x)
C. Scope note:
This class comprises actions intentionally carried out by instances of E39 Actor that result in changes of state in the cultural, social, or physical systems documented. 
This notion includes complex, composite, and long-lasting actions such as the building of a settlement or a war, as well as simple, short-lived actions such as the opening of a door.

Examples:
- the Battle of Stalingrad (Hoyt, 1993)
- the Yalta Conference (Harbutt, 2010)
- my birthday celebration 28-6-1995
- the writing of “Faust” by Goethe (E65) (Williams, 2020)
- the formation of the Bauhaus 1919 (E66) (Droste, 2006)
- the people of Iraq giving the name ‘Quyunjig’ to the place identified by the TGN as ‘7017998’
- Kira Weber working in glass art from 1984 to 1993
- Kira Weber working in oil and pastel painting from 1993

In First Order Logic:
- E7(x) ⇒ E5(x)
D. Scope note:
This class comprises events that end the existence of any instance of E77 Persistent Item. 
It may be used for temporal reasoning about things (physical items, groups of people, living beings) ceasing to exist; it serves as a hook both a terminus post quem and a terminus ante quem. In cases where substance from an instance of E77 Persistent Item continues to exist in a new form, the process would be documented as instances of E81 Transformation.

Examples:
- the death of Snoopy, my dog (fictitious)
- the melting of the snowman (E6)
- the burning of the Temple of Artemis in Ephesos by Herostratos in 356 BC (E7, E6) (Trell, 1945)

In First Order Logic:
- E64(x) ⇒ E5(x)
