Alice has hundreds of prewritten classes for installing objects in an Alice world. Where, in the Alice interface, can you find these prewritten classes?

Is it possible for your Alice program to have more than one instance of the same class? Explain your answer

When you click on the play button in Alice, what method is automatically called? Why?

What is another term commonly used for calling a method?

In Alice one method may call another method, which may require that one or more values be communicated to the method being called. A) what part of instruction holds a value to be communicated? B) what part of the called method receives the value?

List the types of parameters that may be in an Alice method.

Why is it useful to test a method by sending in different arguments?

What is in the distinction between a world level method and an object level method?

Alice is said to have a very primitive form of inheritance because inheritance is not fully defined as part of the Alice system. What kind of methods in Alice (world level or level class) can be used as part of its primitive inheritance capability?

If sound is being imported in an object level method, should the sound be imported for the object or for the world? Explain

If you wish to write a object-level method where another object is involved, what can be done to allow your code to call the other objects methods?

What is the difference between opacity and isShowing properties of an object, in terms of effect on visibility of an object in Alice?
