Question 1

-The following flowchart is an example of a ____.
A) repetition structure
B) dual-outcome selection
C) sequence structure
D) single-outcome selection

Accepted Answer

The answer of 
-The following flowchart is an example of...

Question 2

-The flowchart in the accompanying figure depicts a ____.
A) dual-outcome selection with multiple actions
B) dual-outcome selection
C) selection structure contained in a sequence structure.
D) single-outcome selection

Accepted Answer

A dual-outcome selection with multiple actions is a selection structure that has two possible outcomes, each of which can lead to a different action. The flowchart in the accompanying figure depicts a dual-outcome selection with multiple actions because it has two possible outcomes (Yes and No) and each outcome can lead to a different action (Print "Yes" and Print "No").

Question 3

The JavaScript code for the following algorithm is ____.
If age >= 65 Then
DiscountRate = 0.10
End If
A) if (age >= 65) Then { discountRate == 0.10;} end if
B) if (age >= 65) {discountRate == 0.10} end if
C) if (age >= 65) Then {discountRate = 0.10;}
D) if (age >= 65) {discountRate = 0.10;}

Accepted Answer

The correct JavaScript syntax for an if statement does not use "Then" or "end if", and uses a single equals sign for assignment. Option D correctly uses the if statement syntax and assigns `discountRate` with a single equals sign.

Question 4

A selection contained in the scope of another selection is called a ____.
A) nested selection
B) sequence structure
C) single outcome selection
D) repetition structure

Accepted Answer

A nested selection refers to a situation where one selection structure is contained within another, meaning the inner selection is executed only under certain conditions dictated by the outer selection.

Question 5

The pseudocode for the following problem is ____.
Suppose all students in grade 12 at a high school are to be selected for a field trip, but the boys are leaving on the 8:30 a.m. bus and the girls are leaving at 9:00 a.m.
A) If gradeLevel == 12 Then
Display "Enter M for male, or F for female: "
If gender == "M" Then
Display "Your bus leaves at 8:30 a.m."
Else If
Display "Your bus leaves at 9:00 a.m."
End If
End If

B) If gradeLevel == 12; Display "Enter M for male, or F for female: "
If gender == "M" Then;
Display "Your bus leaves at 8:30 a.m."
Else;
Display "Your bus leaves at 9:00 a.m."
End If;
End If

C) If gradeLevel == 12 Then Display "Enter M for male, or F for female: "
Input gender
If gender == "M" Then
Display "Your bus leaves at 8:30 a.m."
Else
Display "Your bus leaves at 9:00 a.m."
End If
End If

D) If gradeLevel >= 12 Then Display "Enter M for male, or F for female: "
If gender == "M"
Display "Your bus leaves at 8:30 a.m."
Else
Display "Your bus leaves at 9:00 a.m."
End
End If

Accepted Answer

Option C is correct because it includes a prompt for the user to input their gender after checking if the grade level is 12, and then provides the correct departure time based on the gender input. It follows a logical structure and syntax for pseudocode.

Question 6

Based on the grading scale below, what is the most efficient way of determining a grade?
• A if the grade percentage is greater than or equal to 90
• B if it's greater than or equal to 80 and less than 90
• C if it's greater than or equal to 70 and less than 80
• D if it's greater than or equal to 60 and less than 70
• F if the grade percentage is less than 60
A) Test each condition separately.
B) Test the score for a value between 80 and 90 only if the first condition is false.
C) Test to see whether the percentage is 90 or higher.
D) Test to see whether the percentage is less than 60.

Accepted Answer

Testing the score for a value between 80 and 90 only if the first condition is false is efficient because it avoids unnecessary checks once a condition is met.

Question 7

For nested selections that test the same variable for different values, developers created the ____, which is actually a variation of the selection structure.
A) Case structure
B) dual outcome structure
C) If structure
D) For structure

Accepted Answer

The Case structure, also known as the switch-case structure in many programming languages, is designed for situations where a single variable is tested against multiple values, providing a cleaner and more efficient alternative to nested If structures.

Question 8

A(n) ____ structure starts with the pseudocode keyword Select, followed by the name of the variable to test for equality with a variety of values, and ends with a colon.
A) If
B) single-outcome
C) Case
D) dual-outcome

Accepted Answer

A Case structure, often referred to as a "Select Case" or "Switch Case" structure in various programming languages, starts with a keyword like "Select" or "Switch," followed by a variable. It tests the variable against different values, executing different blocks of code depending on which value matches.

Question 9

-The flowchart in the accompanying figure depicts a ____.
A) single-outcome selection
B) Case structure
C) dual-outcome selection
D) if structure

Accepted Answer

The answer of 
-The flowchart in the accompanying figure depicts...

Question 10

In JavaScript, a Case structure starts with the keyword ____, and the name of the variable to test is enclosed in parentheses.
A) Case
B) begin
C) switch
D) select

Accepted Answer

In JavaScript, a case structure starts with the keyword "switch," and the name of the variable to test is enclosed in parentheses.

Quiz 5: The Selection Structure

-The following flowchart is an example of a ____.

-The flowchart in the accompanying figure depicts a ____.

The JavaScript code for the following algorithm is ____. If age >= 65 Then DiscountRate = 0.10 End If

A selection contained in the scope of another selection is called a ____.
