The UML term pair that captures complementary ways of looking at a relationship is "aggregation / composition". Both terms describe types of associations between classes but differ in the degree of ownership and lifecycle dependency between the involved objects. Aggregation implies a weaker relationship where the parent class contains or is linked to other classes but does not strictly control their lifecycle (e.g., a university and its students). Composition, on the other hand, implies a stronger relationship where the parent class has full responsibility for the lifecycle of the associated classes (e.g., a house and its rooms). Understanding these relationships helps model systems more accurately in terms of object ownership and lifecycle management.

The provided image depicts a block diagram of a sensor controller represented as a state machine. The state machine transitions between the following states:

• Initializing
• Calibrating
• Ready
• Acquiring Data

The question specifies the state machine starts in the Ready state and theacquireDataevent triggers the transition.

Analyzing the image, we can identify the following behaviors for the scenario:

• logStatus: This behavior is depicted in the diagram as the first action upon exiting the Ready state. It most likely logs the current state of the sensor controller.
• deploy: The transition from Ready to Acquiring Data triggers the deploy behavior. This likely involves preparing the sensor for data acquisition.
• scanTarget: Upon entering the Acquiring Data state, the scanTarget behavior is initiated. This suggests the sensor controller is actively collecting data from the target.

Therefore, the complete sequence of behaviors islogStatus, followed bydeploy, and lastlyscanTarget, before reaching the Acquiring Data state.

Justification for excluding other options:

• Option A (deploy only) excludes the initial state logging and target scanning actions.
• Option B (logStatus.deploy) excludes the target scanning upon entering the Acquiring Data state.
• Option C (deploy, scanTarget) omits the initial state logging.
• Option E (logStatus.deploy.scanTarget.logStatus) includes an extra logStatus action after target scanning, which is not supported by the diagram.

In conclusion, based on the state machine diagram and the behavior descriptions, option D (logStatus.deploy.scanTarget) accurately reflects the sequence of actions that occur before the sensor controller arrives at the Acquiring Data state.

The correct answer is Option C based on the UML 2 Foundation concepts for activities and pre/postconditions.

Analysis of the Diagram in Option C:

• The diagram depicts an activity named "Withdraw Money".
• There are two diamonds preceding the activity, representing preconditions. Preconditions are conditions that must be true before the activity can be executed.
• The text within the first diamond indicates that "the amount of money to withdraw is entered".
• The text within the second diamond indicates that "the account has sufficient funds".
• This aligns with the scenario where the user must enter a withdrawal amount and the account must have enough money to cover the withdrawal before the "Withdraw Money" activity can proceed.
• Following the activity, there's a diamond labeled "postcondition," indicating a condition that becomes true after the activity is completed.
• The text within the postcondition diamond states that "the account balance is updated." This reflects the scenario where the account balance is updated after a successful withdrawal.

Comparison with Other Options:

• Option A, B, and D do not explicitly show preconditions and postconditions using the diamond notation, making them less suited to represent the scenario where certain conditions need to be met before and after the action.
