Choose the correct answer:

Which UML term pair captures complementary ways of looking at a relationship?

Show Suggested Answer Hide Answer
Suggested Answer: C

UML 2 state machine concepts, here's the analysis of the state machine's behavior after the event and the most likely answer:

State Transition Triggered by Event Ev:

The state machine starts in the 'Start' state. When the event 'Ev' occurs, there's a transition leaving 'Start' with a condition '[VAR is equal to 0]'.

Value of Local Variable VAR:

The prompt specifies that the value of local variable VAR is equal to zero at the time of the event.

State Transition Evaluation:

Since the condition '[VAR is equal to 0]' is true (given VAR's value is zero), the transition from 'Start' to state 'State1' is triggered.

Completion of Run-to-Completion Step:

Upon reaching 'State1', there are no further outgoing transitions or events to consider. 'State1' itself has no exit actions specified. Therefore, the run-to-completion step reaches its end at 'State1'.

Most Likely Answer:

Based on the analysis above, the most likely answer is:

C . End3

Explanation for Other Options:

A . End1:There's no direct path from 'Start' to 'End1'.

B . End2:Similar to option A, there's no transition leading to 'End2' when the event occurs and VAR is zero.

D . Start:The state machine transitions out of 'Start' upon the event 'Ev'. It won't return to 'Start' without another transition.

Possible Ambiguity:

It's important to note that state machines can involve complex logic and actions within states. While 'State1' appears to be a terminal state in this case, it's conceivable that there could be hidden actions within 'State1' that modify VAR or trigger further transitions. The prompt and the provided image don't provide enough information to definitively rule out such possibilities.

Considering the Absence of Mentioned Ambiguity:

Assuming there are no such hidden actions or unspecified behaviors within 'State1', then answer C (End3) is the most reasonable conclusion based on the information available in the prompt and image.

I'm not sure, but I think it might be D) aggregation / composition.

I agree with Willow, generalization / specialization make sense for complementary ways of looking at a relationship.
