Question 1

The my first world method is what type of method?
A) Primitive method
B) Custom method
C) Unique method
D) World-level method
E) None of these

Accepted Answer

The "my first world" method is a world-level method, which is a method that affects the entire world or scene in a programming environment, typically used in educational software like Alice.

Question 2

Which Alice structure is used to have one object move before another object?
A) Do in order
B) Do together
C) Do sequentially
D) Do now
E) None of these

Accepted Answer

The "Do in order" structure is used to have one object move before another object in Alice. It allows for sequential and orderly execution of events.

Question 3

The say method associated with the Frog class is what type of method?
A) Primitive method
B) Custom method
C) Unique method
D) World-level method
E) None of these

Accepted Answer

A

Question 4

Which of the following is the first step in the program development cycle:
A) Write the methods
B) Test the methods
C) Design the program
D) Debug the methods
E) None of these

Accepted Answer

The first step in the program development cycle is to design the program. This involves identifying the problem to be solved, defining the input and output requirements, and mapping out the logic and flow of the program. Only after the program has been designed can methods be written, tested, and debugged.

Question 5

Which of the following structures are used to add explanatory notes into a method?
A) Do in order
B) Do together
C) Note
D) Comment
E) None of these

Accepted Answer

Comments are used to add explanatory notes into a method.

Question 6

Which of the following identifiers utilizes the camelCase naming convention?
A) MakeCake
B) goForIt
C) Runspotrun
D) tryagain
E) None of these

Accepted Answer

CamelCase naming convention starts with a lowercase letter and then capitalizes the first letter of each subsequent concatenated word. "goForIt" follows this pattern.

Question 7

All classes have custom methods.

Accepted Answer

Not all classes have custom methods; some may only use inherited methods from a superclass or default methods provided by a language's standard library.

Question 8

Which type of error will not prevent a program from running, but will produce incorrect results?
A) Syntax error
B) Runtime error
C) Logical error
D) Pseudoerror
E) None of these

Accepted Answer

Logical errors occur when the code is syntactically correct and runs without errors, but produces unexpected or incorrect results. These errors may not prevent a program from running, but they can cause the program to operate incorrectly.

Question 9

How are method calls added to a method in the Method Editor?
A) By dragging the method from the Object Tree.
B) By typing the method call.
C) By dragging the method from the Method Window.
D) By dragging the method tile from the Details Panel to the Method Editor.
E) None of these

Accepted Answer

Method calls can be added to a method in the Method Editor by dragging the method tile from the Details Panel to the Method Editor.

Question 10

Which Alice structure is used to have two objects move towards each at the same time?
A) Do in order
B) Do together
C) Do sequentially
D) Do now
E) None of these

Accepted Answer

The "Do together" structure allows two or more actions to occur simultaneously, which is ideal for having two objects move towards each other at the same time.

Question 11

Which of the following is a primitive method?
A) Run
B) Jump
C) Think
D) Play
E) None of these

Accepted Answer

The answer of Which of the following is a primitive...

Question 12

When creating a new Alice world, which of the following should be done prior to the rest?
A) Writing new methods for an object
B) Setting an object's properties
C) Adding one or more objects
D) Running the program
E) Clicking the Restart button

Accepted Answer

Adding one or more objects is typically the first step when creating a new Alice world. This allows the user to then set the properties and write new methods for the objects. Running the program and clicking the Restart button would come after these initial steps.

Question 13

Which of the following is not a primitive method?
A) Move
B) Turn
C) Roll
D) Resize
E) None of these

Accepted Answer

Primitive methods typically include basic operations such as move, turn, and resize. "Roll" could be considered a specific type of turn or move in certain contexts, but it is not universally recognized as a separate primitive method across all programming or computational contexts. Therefore, since all listed options can be argued to be primitive methods in some contexts, "None of these" is the correct choice.

Question 14

Only certain Alice objects have all of the primitive methods.

Accepted Answer

All Alice objects have access to a set of primitive methods, such as move, turn, and roll, which are inherent to the Alice programming environment.

Question 15

The foottap method associated with the Frog class is what type of method?
A) Primitive method
B) Custom method
C) Unique method
D) World-level method
E) None of these

Accepted Answer

The foottap method is a custom method that is specific to the Frog class and is not a built-in or primitive method.

Question 16

An event is a set of instructions that causes some action to take place.

Accepted Answer

An event is an occurrence or action that typically triggers a response or process, not a set of instructions.

Question 17

Using the camelCase naming convention is a good way to have easy-to-read, meaningful identifiers.

Accepted Answer

CamelCase allows us to create descriptive, readable identifiers by capitalizing the first letter of each word except for the first one. This convention is widely used in programming languages and makes it easier to spot variable or function names in code.

Question 18

Pseudocode is written in the following language:
A) Basic
B) Machine language
C) Java
D) English
E) None of these

Accepted Answer

Pseudocode is not a programming language, but rather a written representation of a program's logic using natural language (usually English). It is used to plan out the structure and flow of code before it is written in a specific programming language.

Question 19

When you call the walk method of the Walking People class, what must be specified as an argument?
A) distance
B) speed
C) duration
D) style
E) None of these

Accepted Answer

The argument that must be specified when calling the walk method of the Walking People class is the distance the person will walk. This is because the method is designed to move the person a specific distance, not for a specific duration or at a specific speed or style.

Question 20

What is the name of the default world method that automatically runs when an Alice program is executed?
A) the first method
B) main
C) my first method
D) start
E) None of these

Accepted Answer

In Alice, the default world method that automatically runs when a program is executed is called "my first method".
