Answer:

Explanation:

I believe the best process for this would be for the developer to create a class that has methods for opening up and reading all the data from each one of the sources. They should also add methods for easy manipulation, and writing to these files. This would allow the development team to easily reference this class and call the methods with a single line of code so that they can get and write the data from each individual source as needed. This design will also allow them to use all of these sources easily from any application by simply referencing the class and without having to change any code.

mr Goodwill [35]

Answer:

Replace the comment with:

(c) double hours = Math.abs (marker1 - marker2) / 60.0;

Explanation:

See attachment for right presentation of question

Analyzing the options:

(a): May return a negative result

This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.

This literally is not different from marker1 - marker2

(b): Incorrect expression

This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.

(c) This option is correct

This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)

(d) & (e) Integer division

When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
