Choose the correct answer.
Consider the following two activity diagram fragments labeled Fragment 1 and Fragment 2. The JoinSpecification for Fragment 1 is completely specified, but the JoinSpecification for Fragment 2 is not.

Which join specification for Fragment 2 will make it exhibit the same behavior as fragment 1? Assume that activities with the same names exhibit the same behavior
A. The question cannot be answered because Activity Diagram Fragment 1 is ambiguous
B. b1 or b2 or b3 or b4
C. (b1 or b2) and b3 and b4
D. (b1 or b?) and (b3 or b4)
正解：C

Choose the correct answer
A system consists of two identical tanks each containing a different level of fluid. The tanks are connected together by a port at the bottom of each tank. This system is modeled m the following diagram:

Which statement is true?
A. The block Fluid, which types item property flow 1 ->2. has a value property press : Pressure with a default value of null
B. Both port p1 on pan t1. and port p1 on t2. must have values defined for value properties /rate and press
C. Parts t1 and t2 each use part instances to redefine the value of property level : Height
D. The value of /rate for item property flow 1->2 is positive for flow from t1 to t2. and negative for How in the other direction
E. The value property /rate : flow rate is a derived property, which accommodates calculating its value based on oilier properties
正解：E

Given the following diagram:

What needs to be determined in order to model the connection between components s0 and u3 in more detail?
A. which parts of each component participate in a reference association
B. whether component s0 subclasses component u3
C. whether any part that belongs to component s0 subclasses a pan that belongs to component u3
D. which parts of each component participate in the connection
正解：D
