How ate use cases and requirements used for requirements analysis in SysML?
A. in a SysML model, either use cases or requirements are modeled, but never both
B. Use cases are a relic from UML and are. strictly speaking, useless in a SysML model
C. Use cases are good for capturing functional requirements. For nonfunctional requirements, the requirement element is needed
D. Use cases are the basis for all requirements in a model. Requirements refine the use cases by adding additional information through then properties.

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. The value property /rate : flow rate is a derived property, which accommodates calculating its value based on oilier properties
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. Both port p1 on pan t1. and port p1 on t2. must have values defined for value properties /rate and press

A. Option A
B. Option B
C. Option C
D. Option D
Choose the correct answer.
