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

Which of the following definitions best describes 'E74 Group'?

A. Scope note:
This class comprises the states of objects characterised by a certain condition over a time-span. 
An instance of this class describes the prevailing physical condition of any material object or feature during a specific instance of E52 Time-Span. In general, the time-span for which a certain condition can be asserted may be shorter than the real time-span, for which this condition held.
The nature of that condition can be described using P2 has type. For example, the instance of the concept “condition of the SS Great Britain between 22(nd) September 1846 and 27(th) August 1847” can be characterized as an instance “wrecked” of E55 Type.

Examples:
- the "reconstructed" state of the “Amber Room” in Tsarskoje Selo from summer 2003 until now (Owen, 2009)
- the "ruined" state of Peterhof Palace near Saint Petersburg from 1944 to 1946 (Maddox, 2015)
- the state of my turkey in the oven at 14:30 on 25(th) December 2002 [P2 has type: E55 Type “still not cooked”] (fictitious)
- the topography of the leaves of Sinai Printed Book 3234.2361 on the 10(th) July 2007 [described as: of type "cockled"] (fictitious)

In First Order Logic:
- E3(x) ⇒ E2(x)
B. 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)

In the wider sense this class also comprises official positions which used to be regarded in certain contexts as one actor, independent of the current holder of the office, such as the president of a country. In such cases, it may happen that the the concept never had more than one member. A joint pseudonym (i.e. a name that seems indicative of an individual but that is actually used as a persona by two or more people) is a particular case of the concept.
A gathering of people becomes an instance of the concept when it exhibits organizational characteristics usually typified by a set of ideas or beliefs held in common, or actions performed together. These might be communication, creating some common artifact, a common purpose such as study, worship, business, sports, etc. Nationality can be modelled as membership in an instance of the concept. Married couples and other concepts of family are regarded as particular examples of the concept.

Examples:
- the Impressionists (Wilson, 1994)
- the Navajo (Correll, 1972)
- the Greeks (Williams, 1993)
