Document 2: A Sense of Wonder: A Sense of Wonder is the fifteenth studio album by Northern Irish singer-songwriter Van Morrison released in 1984.

Document 15: New Woman: The New Woman was a feminist ideal that emerged in the late nineteenth century and had a profound influence on feminism well into the twentieth century. The term "New Woman" was coined by writer Sarah Grand in her article "The New Aspect of the Woman Question," published in the "North American Review" in March 1894. The term was further popularized by British-American writer Henry James, to describe the growth in the number of feminist, educated, independent career women in Europe and the United States. Independence was not simply a matter of the mind: it also involved physical changes in activity and dress, as activities such as bicycling expanded women's ability to engage with a broader more active world. The New Woman pushed the limits set by male-dominated society, especially as modeled in the plays of Norwegian Henrik Ibsen (1828–1906).
