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

Which of the following definitions best describes 'E68 Dissolution'?

A. Scope note:
This class comprises the deaths of human beings. 
If a person is killed, their the concept should be instantiated as the concept and as E7 Activity. The the concept or perishing of other living beings should be documented as instances of E64 End of Existence.

Examples:
- the murder of Julius Caesar (E69, E7) (Irwin, 1935)
- the the concept of Senator Paul Wellstone (Monast and Tao, 2002)

In First Order Logic:
- E69(x) ⇒ E64(x)
B. Scope note:
This class comprises the events that result in the formal or informal termination of an instance of E74 Group. 
If the the concept was deliberate, the the concept event should also be instantiated as an instance of E7 Activity.

Examples:
- the fall of the Roman Empire (Whittington, 1964)
- the liquidation of Enron Corporation (Atlas, 2001)

In First Order Logic:
- E68(x) ⇒ E64(x)
C. Scope note:
This class comprises events that destroy one or more instances of E18 Physical Thing, such that they lose their identity as the subjects of documentation.
Some the concept events are intentional, while others are independent of human activity. Intentional the concept can be documented by classifying the event as both an instance of the concept and of E7 Activity. 
The decision to document an object as destroyed, transformed, or modified is context-sensitive: 
1. If the matter remaining from the the concept is not documented, the event is modelled solely as an instance of the concept. 
2. An event should also be documented using E81 Transformation if it results in the the concept of one or more objects and the simultaneous production of others using parts or material from the original. In this case, the new items have separate identities. Matter is preserved, but identity is not.
3. When the initial identity of the changed instance of E18 Physical Thing is preserved, the event should be documented as an instance of E11 Modification.

Examples:
- the the concept of Herculaneum by volcanic eruption in 79 AD (Camardo, 2013)
- the the concept of Nineveh (E6, E7) (River, 2016) 
- the breaking of a champagne glass yesterday by my dog (fictitious)

In First Order Logic:
- E6(x) ⇒ E64(x)
D. Scope note:
This class comprises the births of human beings. the concept is a biological event focussing on the context of people coming into life. (E63 Beginning of Existence comprises the coming into life of any living being.) 
Twins, triplets, etc. are brought into life by the same instance of the concept. The introduction of the the concept event as a documentation element allows the description of a range of family relationships in a simple model. Suitable extensions may describe more details and the complexity of motherhood since the advent of modern medicine. In this model, the biological father is not seen as a necessary participant in the the concept.

Examples:
- the the concept of Alexander the Great (Stoneman, 2004)

In First Order Logic:
- E67(x) ⇒ E63(x)

Answer: Scope note:
This class comprises the events that result in the formal or informal termination of an instance of E74 Group. 
If the the concept was deliberate, the the concept event should also be instantiated as an instance of E7 Activity.

Examples:
- the fall of the Roman Empire (Whittington, 1964)
- the liquidation of Enron Corporation (Atlas, 2001)

In First Order Logic:
- E68(x) ⇒ E64(x)
