Answer : B

The answer is B, 'The transmitted object may be copied and the object identity may be changed.' When an object is sent from one action to another, it is not always guaranteed that the identity of the object will be preserved. It depends on the semantics of the transmission, which may allow for object copying, and hence the object identity may change during the process.

UML 2.5 Specification: The section on send actions within activity diagrams describes the behavior of object flows, including transmission semantics regarding object identity and copying.

Answer : C

Before the SomeActivity action is executed, the value of 'Counter' is not specified in the given diagram fragment; therefore, we cannot assume that it has a value. This leads to the answer C, 'It is empty.' In UML, unless an initial value is explicitly specified for a variable, it cannot be assumed to have a default value.

UML 2.5 Specification: The UML specification's section on variables and actions would explain that unless initialized, variables do not have a default value.

Answer : D

'QueryCustomerFromParcel' is annotated with the transformation stereotype, which indicates that it is a behavior element that specifies how to convert input objects into output objects. Therefore, the answer is D, a Behavior element, for example, an Activity, State Machine, or OpaqueBehavior. In UML, the transformation stereotype is applied to specify that an action or activity is responsible for transforming an input (in this case, 'Parcel') into an output ('Customer'), typically by employing a specific behavior element.

UML 2.5 Specification: Section on Object Flows describes how transformations can be used within activity diagrams to turn inputs into outputs using behavior elements.

Answer : B

The correct answer is B, which uses a selection edge to specify task behavior based on task priority. In UML, an object flow with a selection property is used to select objects from a collection according to some criterion, which is typically represented by a Boolean expression. In the case of B, the selection criterion is described as 'ordering = the most important first', indicating that tasks are selected to be executed based on their priority.

UML 2.5 Specification: The UML 2.5 specification describes how selection behaviors can be applied to object flows to filter objects according to specific criteria, such as priority in this scenario.

Answer : C

The correct answer is C, which uses a transformation edge to indicate that when an order is closed, information is transformed or processed to notify the customer. This is expressed in UML with an object flow that has a transformation property, which specifies how an object is transformed from one state to another as it flows along the edge. This is appropriate for a scenario where closing an order leads to the creation of a customer notice, implying some form of transformation or processing of the order information to generate the notice.

UML 2.5 Specification: The UML 2.5 specification details how object flows with transformations can be used to show that one piece of data is transformed into another as it flows from one action to another.
