Answer:
mathClass = Roster([('Jacob', 65), ('Frankie', 86), ('Lina', 94), ('Arnold', 63), ('Amanda', 87)])
Explanation:
An Instance of a class, refers to making a new object of that class. They belong to the class from which they are derived. The meaning of this is that every instance of a class that is created, will have its own set of variables with different values initialized by the constructor call, so we can make several objects of a class and define their behavior. In this question, we are asked to make a new instance of the class Roster called mathClass and at the constructor call we pass the variables of this new object as an argument.

Answer:
C)An error message is issued.
Explanation:
If we try to open a file for reading when that file does not exist, we will get an error message.
For example, in Java we will encounter a FileNotFoundException as in the code below:
try {
FileInputStream fis = new FileInputStream("myFile.txt");
DataInputStream dis = new DataInputStream(fis);
BufferedReader br = new BufferedReader(new InputStreamReader(dis));
String str = null;
while ((str = br.readLine()) != null) {
System.err.println(str);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
If the file myFile.txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.
