The only line that will work in the code above is line 5, which calls the draw( ) method on an instance of the Triangle class. Triangle shape4 = new Triangle(); shape4.draw( );
1. Shape shape = new Shape(); - This line will not work because Shape is an interface and cannot be instantiated.
2. ComplexShape shape2 = new Triangle(); - This line will work, but only if the ComplexShape class has a constructor that takes a Triangle as a parameter. Since the given code does not have such a constructor, this line will not work.
3. ComplexShape shape3 = new ComplexShape(); - This line will work, but it does not create an instance of a shape that can be drawn. It only creates an empty ArrayList within the ComplexShape class.
4. shape3.draw( ); - This line will not work because shape3 is a ComplexShape object, which does not have a draw( ) method.
5. Triangle shape4 = new Triangle( ); shape4.draw( ); - This line will work because it creates an instance of the Triangle class, which implements the Shape interface and has a draw( ) method. The draw( ) method will print a "drawing triangle" to the console.

The five components of accounting systems are source documents, input devices, information processors, information storage, and output devices. Group startsTrue or False
Answer:
True
Explanation:
Source documents are business documents that track business transactions.
Input devices, like bar code scanners, keyboards, and modems, are tools used to enter transaction information into the accounting system.
Information processors take the raw data from the input devices and post it to ledgers, journals, and reports.
Information storage is the component of the system that stores the reports and ledgers created by the information processors.
Output devices like monitors, printers, and projectors are any devices that take information from the system storage and display it in a useful way.
These components are all what help an accounting system gather financial data, translate it into useful information, and communicate it with decision makers.
