A reader using a historical lens to analyze a text will be most concerned with

the role of women.

the use of language.

culture and events.

gender stereotypes.

The question is asking what would a reader using a historical lens to analyze a text be most concerned with. When we talk about the history, what we are most interested in is what happened, and especially: what kind of significant events that shape the present, happened. We are less interested in the life of people at that time, but rather in the significant events, such as wars and creation of countries. So the best answer is: culture and events.
