What is a 'control operator'?

A) it is an activity that can output control tokens via a parameter node.
B) It Is an activity node that allows a modeler to specify the use of mathematical operators such as plus minus, multiply, or divide.
C) It Is a special kind of activity node that can be used to control the flow of tokens into an activity.
D) It Is the general term for any element of an activity that can handle control tokens.

2. Choose the correct answer
Which statement is true about the read only keyword when it appears next to a property?

A) It specifies that the corresponding property cannot be redefined
B) It specifies that the value of the corresponding property cannot change during the lifetime of its owner.
C) It specifies that the value of the corresponding property can be changed by its owner, but can only be read by other blocks
D) It states that the corresponding property is provided for reading purposes only

3. Choose the correct answer.

4.
Assume the block is in A-State when two evCs ate received.
What is a plausible sequence of behaviors that occurs when a subsequent evG occurs?

A) stop activity X (if running), action 2, action 8, action 5, start activity Y, action 7, action 7
B) stop activity X (if running) action 8, action 5, start activity Y, action 7, action 7
C) action 1. stop activity X (if running), action 7, action 8, action 5, start activity Y
D) stop activity X (if ninning). action 2, action 8, action 5, start activity Y, action 7, action 7, action 6
E) stop activity X (if running), action 8, action 5, start activity Y, action 7

5. Choose the correct answer.
The formula for the determinant of a square 2X2 matrix.
|ab|
|cd|
is a'd-b'c A subsystem receives one message for each value (i e. a(v) b(v). c(v) and d(v) where v is a real number) These messages can be in any order, and the ensure sequence is followed by an "end" message. The subsystem must calculate the determinant and output it upon receipt of the end message If there are multiple messages for one value (e g . two a(v) messages), or the end message is received before all values have been received, the subsystem should signal an error.
