The term euphemism refers to polite, indirect expressions which replace words and phrases considered harsh and impolite or which suggest something unpleasant.
Euphemism is an idiomatic expression which loses its literal meanings and refers to something else in order to hide its unpleasantness. For example, “kick the bucket” is a euphemism that describes the death of a person. In addition, many organizations use the term “downsizing” for the distressing act of “firing” its employees.
Pathos is like: look at this poor dog *plays sad music* "for every dollar, you can save a dog" (appeals to your feelings)
Logos is like: according to science, 97% of the population likes carrots (based on stats)
Ethos is like: since im a doctor, you should trust me. (Based on personal experience)
The last one is the correct answer.
As The Feminine Mystique is a purely feminist book, is pretty easy to think that Friedan is giving us a feminist view on the way women were seen in the sixties. Feminism intention is to find equality among sexes and what Friedan does in this extract, is to show the key terms releated to feminism: "suburban wife", "dream image", "freed by science and labor", "healthy, beautiful, educated, concerned about her husband and children".
