Answer:
In a biased Web site it is often hard to distinguish fact from opinion and advertisements.
Explanation:
It is not difficult to identify a biased text. There are some indications that report when the site intends to direct reader opinion to a particular conclusion.
A non-biased publication is concerned with informing the reader in a neutral manner, paying attention to the facts so that the reader makes his own conclusion about it. When a trusted website takes advantage of a position, it must be explicit in the text, such as the opinion articles of some newspapers.
However, biased websites do not clearly take sides, but try to influence the reader during the text. This is easily observed through the sensationalism of the news, with the use of alarming jargon on the subject, fakenews, and arguments that direct the reader to a single conclusion, with contempt for the contradictory argument.
