AP CSP Boolean Logic 2

Given the procedure:

What will be displayed after the following statement is executed?

DISPLAY ( adjustCount (11) + adjustCount (16) )

• 28

• 32

• 33

• 35

Two grids are show. Each grid contains a robot represented as a triangle. Both robots are initially facing left. Each robot can move into a white or gray square, but cannot move into a black region.

For each grid, the program below is intended to move the robot to the gray square. The program uses the procedure Goal_Reached ( ), which evaluates to true if the robot is in the gray square and evaluates to false otherwise.

• Grid I only

• Grid II only

• Both grid I and grid II

• Neither grid I nor grid II

Consider the code segment above.

If the variables onTime has the value of true and absent has the value false, what is displayed as a result of running the code segment?

• Hello.

• Is anyone there?

• Hello. Is anyone there?

• Hello. Better late than never.

In the program below, the initial value of x is 0 and the initial value of y is -2.

What is displayed as a result of running the program?

• Foxtrot

• Hotel

• November

• Yankee

The diagram shows a circuit with three gates, where the output from two AND gates are sent into an OR gate. The circuit has four inputs (A, B, C, D), two for each AND gate.

If the final output is 0, what is a possible state of the inputs A/B/C/D?

Choose 1 answer.

• A = 0, B = 0, C = 0, D = 0

• A = 1, B = 1, C = 0, D = 1

• A = 0, B = 1, C = 1, D = 1

• A = 1, B = 0, C = 1, D = 1

The diagram shows a circuit composed of two logic gates labeled OR and AND. Each gate takes two inputs and produces a single output.

If the input A is false and input C is true, which of the following best describes the output of the AND gate?

• The output will be true no matter what the value of input B is.

• The output will be false no matter what the value of input B is.

• The output will be true if input B is true; otherwise it will be false.

• The output will be false if input B is true; otherwise it will be true.

The two variables age and day are initialized with the values shown.

age <-- 16

day <-- "Tuesday"

Choose the compound conditional that evaluates to true.

• (age > 10) AND (age < 15)

• NOT (age > 10)

• (day = "Tuesday") OR (age < 12)

• NOT ( (age = 16) OR (day = "Tuesday") )

This program uses a conditional to determine if seafood is safe to consume.

In which situations will rating be "unsafe"?

Note that there may be multiple answers to this question.

Choose 1 answer.

• When seafood is "mollusk" and daysFrozen is 7

• When seafood is "tuna" and daysFrozen is 6

• When seafood is "salmon" and daysFrozen is 7

• When seafood is "salmon" and daysFrozen is 6

The following expression is from the data loading logic of a website.

NOT ( state ≠ "loading" AND result = "error" )

Which of these expressions are logically equivalent?

• state ≠ "loading" AND result ≠ "error"

• state = "loading" AND result = "error"

• state = "loading" OR result ≠ "error"

• state ≠ "loading" OR result = "error"
