Final answer:
The best summary emphasizes the need for caution when evaluating Internet sources by considering web addresses and highlights that domain extensions can help determine a source's credibility.
Therefore, the correct answer is: option 'Students should approach sources found on the Internet with caution by considering web addresses.'
Step-by-step explanation:
The web address contains information about the location of the webpage. It is also known as the URL (uniform resource locator).
A domain extension on a web address, such as .edu, .gov, or .org, can give students information about the source's credibility and reliability. Websites with these extensions are often more trustworthy than those ending in .com, which may be commercial.
Moreover, credible sources can sometimes be found in academic article databases or recommended by faculty, rather than through a simple web search.
Another important tool in verifying digital sources is the DOI (Digital Object Identifier), which is a unique identifier used to locate digital content. Unlike URLs, which can change over time, a DOI remains constant, making it a more reliable means of locating scholarly articles.
