Which of the following might cause a text to have multiple perspectives? More than one author, additional facts, difficult topic or deep understanding?

All of the options mentioned—more than one author, additional facts, difficult topic, and deep understanding—can cause a text to have multiple perspectives.

Having more than one author means that different writers could present varying viewpoints or opinions on the same topic. Each author may bring their own bias or interpretation, resulting in multiple perspectives being present in the text.

The inclusion of additional facts can also contribute to multiple perspectives in a text. By presenting different evidence or data, the text can accommodate various viewpoints or interpretations of the subject matter.

Similarly, addressing a difficult topic often involves exploring different angles, arguments, or opinions. This can lead to the inclusion of multiple perspectives within the text.

Lastly, a deep understanding of a topic can allow the author to explore it from various points of view. This could involve considering different theories, historical contexts, cultural perspectives, or personal experiences related to the topic, adding multiple perspectives to the text.
