Answer:
The first step to finding support for a theme across documents is to analyze the differences in similar documents. By closely examining multiple documents that relate to the theme in question, you can identify commonalities and differences in the way the theme is addressed or depicted. This analysis helps establish a foundation for understanding the various perspectives and interpretations present within the documents. It allows you to identify the key ideas, motifs, or patterns that emerge across the texts, which can then be used as evidence to support the theme you are exploring. By comparing and contrasting the documents, you gain a deeper understanding of the nuances and complexities surrounding the theme and lay the groundwork for further analysis and interpretation.
