Final answer:
The excerpts do not explicitly detail Edna's feelings about childbirth; however, themes in literature suggest motherhood experiences can be complex and relate to broader notions of women's roles, such as the idea of maternal feminism.
Step-by-step explanation:
The revelation connected to Edna's childbirth experiences is not explicitly stated in the provided excerpts, but a general analysis of maternal themes in literature suggests that childbirth and motherhood experiences can be quite complex and multifaceted. Often, these themes explore the emotional and psychological impacts of motherhood. For instance, the concept of maternal feminism mentioned in one of the excerpts implies a recognition of the capacity of women to nurture and shape the future outside the confines of the home. This concept touches upon the empowerment of women through the lens of motherhood, distancing from the traditional perception that equates womanhood solely with childbirth and domesticity.
Based on the context and clues offered by related literature, option (a) Edna had very difficult experiences during childbirth seems less likely compared to (b) She is not particularly comfortable with the concept of birth, which might tie into the broader context of a woman's revelation and relation to her roles within society. However, without more explicit information on Edna's personal experiences, it is difficult to provide a definitive answer to the student's question.
