How might an author’s background and time period affect a piece of writing?

they can affect the author’s perspective and in turn the theme and purpose for the writing.

an author’s background and time period will only affect voice and word choice.
they will affect only the author’s choice of topic and the genre of the writing.

The correct answer is A. They can affect the author’s perspective and in turn the theme and purpose for the writing.

Explanation:

An author's background refers to his education, social status, personal experiences, values and other elements related to the circumstances of the life of the author, as well as the historical period in which the author writes. These elements influence in an important way different elements of the literary work of the author including the perspective of the author that changes the theme and the purpose for writing.

This can be explained as the values and perspective of the author are linked to his background and historical context and this influences the theme considering most of the authors write about the issues or situations that are particular to the historical period in which they live, but also provide their perspective about these situations, for example, the world wars were a major theme for the authors that lived during the 20th century, but each of them provided different perspectives about this.Also, the purpose of writing can change as some authors will prefer to narrate or entertain and others to persuade the audience.

Considering this, it can be concluded an author's background and time period affects a piece of writing as "They can affect the author’s perspective and in turn the theme and purpose for the writing".
