Question

improve our ability to summarize a text.
broaden the scope of our analysis of a text.
maintain a separation between ourselves and a text.
ignore differences between ourselves and an author.
identify meaningful features of a texts organization.

Explanation:

Understanding oneself and others helps in looking at a text from multiple perspectives, thus expanding the scope of analysis. Summarizing is not directly related to self - and other - knowledge. Maintaining separation, ignoring differences, and identifying text organization features are not the main benefits of self - and other - knowledge in reading.
