Answer:
The Internet
Explanation:
Why? The internet has done twice if not thrice what the printing press has done. The printing press allowed for dissemination of information and knowledge to the population through its mechanical movable printing capability and speed of book publishing. However its reach was highly limited by the physical attributes of the machines and having to transfer books and papers in spreading them to certain destinations. This limitation has been eliminated by the internet as one is able to receive a book written today in seconds and not physically but through electronic means. In other words, information need not be transferred physically, also accessbility and cost of getting information has been highly improved with the internet.

Answer:
1. A function can use variables as parameters.
2. A function can have more than one parameter.
3. The definition of a function must come before where the function is used.
Explanation:
<u>The definition of a function can come before or after it is used</u> - I am pretty sure it cannot be placed after the function is being used. It should always come before it is used, so this statement is false.
<u>A function can use variables as parameters</u> - this is true, variables are just labels to hold data.
<u>A function can have more than one parameter</u> - this is true.
<u>A function must have a return value</u> - functions do not always have to <em>return</em> values. It could simply print, so this statement is false.
<u>The definition of a function must come before where the function is used</u> - As said earlier, the definition of functions must come before it is used/called. This statement is true.
Hope this helps :)
