Answer:
Explanation:
The question above is missing many details and are actually various questions in one. I will answer each one seperately below...
A. The piece of code to get the ID in this code snippet that needs to replace XXX would be the following ... System.out.println("Student ID: " + s.getID());
B. A static main() can declare and create objects. Once these objects are created their instance methods can then be called.
C. Integer score1 = 72;
int score2 = 85;
Character grade = 'C';
In the above code snippet, the information stored in score1, score2, and grade are the following... obj reference, 85, obj reference. This is becasue both Integer and Character are classes and the values being passed to their variables are referencing that object class, while score2 is a primitive type of int and is therefore simply a number.
D. The statement that is true is ... Contents of a Double instance can be modified after initialization. Objects can be modified by calling its setter methods after initializing it.

Answer:
B.lightning striking a tree
Explanation:
The crowd dispersing in all directions is not a closed-loop by any means, and students jogging around an oval track as well is not a closed-loop, and also not a cross country run from one point to another. However, the lightning striking a tree is a closed loop that best models a circuit. And as lightning strikes the tree, like a closed circuit, tree catches the fire, or in circuitry words, the current is generated, and tree catches the fire due to it, just like bulb starts glowing.
