A hyperlink is a link that can direct a person to another website when clicked. So the answer would click on the link to go directly to a website. To insert an image or sound you would use something else. And a hyperlink doesn't restrict a person to just the publisher information. I hope this helps!
Bias is when the author uses or implements their beliefs into an article, without using factual evidence. An example could be an author saying that apples are bad for you, when really they just don’t like apples.
