Correct. To return "Eligible to drive", the condition age >= 16 AND hasLicense = true must be true. In this option, age is 17 (which is >= 16) and hasLicense is true. Both parts of the AND condition are true, so the entire condition is true. The other options fail one or both parts of the condition.

Correct. The expression getBonus(5) is evaluated first. The procedure call returns 5 * 10, which is 50. The assignment statement then becomes finalScore ← 50 + 50, which assigns 100 to finalScore. This value is then displayed. Distractor D incorrectly calculates (50 + 5) * 10. Distractor B incorrectly calculates 50 + 5. Distractor C incorrectly calculates 50 * 10.

Correct. The procedure call passes the argument "Explorer" to the parameter name. The procedure then displays the string literal "Welcome, " followed by the value of name, which is "Explorer". The DISPLAY command adds a space after each output, resulting in "Welcome, Explorer". Distractor B incorrectly displays the parameter name instead of its value. Distractor C only shows a portion of the output. Distractor D shows the code statement itself, not its output.

Correct. Arguments in a procedure call are matched to parameters based on their position. The second argument in the call is 1200, which corresponds to the second parameter in the procedure definition, cost. Therefore, cost is assigned the value 1200. The other distractors represent the values assigned to the other parameters or the parameter name itself.

Correct. Parameters are the variables listed in a procedure's definition (num1, num2). Arguments are the actual values (5, 10) passed to the procedure when it is called. Distractor B incorrectly reverses the terms. Distractor C incorrectly identifies the values as variables. Distractor D incorrectly describes the flow of data; values are passed into, not returned to, parameters.

Correct. The procedure calculate is called with a as 5 and b as 3. Inside calculate, the procedure double is called with the argument a, which is 5. double(5) returns 5 * 2 = 10. The variable temp is then assigned the value of 10 + b, which is 10 + 3 = 13. The value of temp, 13, is then displayed.

Correct. This call provides "right" for the direction parameter and 4 for the steps parameter. The IF condition ("right" = "left") is false, so the ELSE block executes, causing a right turn. The REPEAT loop then executes 4 times, moving the robot forward 4 squares. Distractor B provides the arguments in the wrong order. Distractor C provides too few arguments. Distractor D provides right as a variable name instead of the string literal "right".

Correct. The loop iterates through the list. For each element, it calls isPositive. isPositive(-2) is false. isPositive(0) is false. isPositive(5) is true, so count becomes 1. isPositive(10) is true, so count becomes 2. isPositive(-8) is false. The final value of count, which is 2, is displayed.

This question tests AP Computer Science Principles skills: understanding and calling procedures. In programming, procedures are blocks of code designed to perform a specific task; they are called within a program to execute their defined operations. In the provided scenario, procedures FilterByDate, ComputeAverages, and GenerateReport work together to produce a weather report. Data flows through these procedures via parameters and return values in a logical sequence. Choice B is correct because it accurately reflects the logical order: first filter the data to the relevant date range, then compute averages on that filtered subset, and finally generate the report from those computed values. Choice C is incorrect because computing averages before filtering would waste resources calculating values for data that will be discarded, and could produce incorrect results. To help students: Emphasize understanding the role of each procedure within the program and practice tracing data flow through parameters and return values. Encourage students to think about efficiency and logical dependencies when determining the correct order of procedure calls.

Correct. A procedure call interrupts the normal sequential execution. The flow of control transfers to the body of the called procedure. After the procedure finishes, control returns to the point immediately following the call. Distractor B describes sequential execution without a call. Distractor C is incorrect because procedure calls are meant to be executed. Distractor D incorrectly describes program termination.
