If it’s computer files, that would be System Software and Application software. 
“The System Software is the programs that allow the computer to function and access the functionality of the hardware. Systems software sole function is the control of the operation of the computer.
Applications software is the term used for programs that enable the user to achieve specific tasks such as create a document, use a database or produce a spreadsheet.”
        
             
        
        
        
Answer:
showProduct(int,double)
for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.
Explanation:
The code is 
-        <em>public static void showProduct (int num1, double num2){</em>
- <em>       int product;</em>
- <em>       product = num1*(int)num2;</em>
- <em>       System.out.println("The product is "+product);</em>
- <em>       }</em>
showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.
If showProduct( 10,10.0) is called the output will be 'The product is 100'.
Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there. 
This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.

Answer:
A. using a hook in his opening
B.  detailing the speech’s objectives
E. letting his audience know what to expect
Explanation:
Opening his speech using a quotation is a strategy of using a narrative hook, or simply hook, by Ian. Giving a grand and enticing opening is what makes an audience to pay attention and listen to what the speaker has to say in his speech. So, first strategy used by Ian is using a hook in his opening.
Another strategy used by Ian is giving objective details of his speech. By outlining what he will be covering in his speech, Ian is letting his audience know what to expect from the speaker and his speech, and also gave details of his speech.
So, option A, B, and E are correct.
