Answer:
Newspaper articles that present a particular viewpoint or support a certain opinion are called editorials.
Step-by-step explanation:
The editorial belongs to the narrative genre, and consists of an expository-argumentative text, usually not signed, that explains, evaluates and judges a news event of special importance. It is a collective opinion, an institutional judgment formulated in accordance with the ideological line of the media. In other words, it is an opinion or comment made by the editor about the news, and written according to the experiences of the editor or the editors.
It is a traditional text of newspapers and usually appears in a preferred place within the opinion section of a media. Although the editorial does not bear a signature, since it summarizes a collective opinion, there are journalists in charge of its writing, the so-called editors. In many cases, the newspaper director writes it.
