Answer:
Societal pressure on women to look a certain way
Step-by-step explanation:
The excerpt you were given is the following:
"If I have only one life, let me live it as a blonde," a larger-than-life-sized picture of a pretty, vacuous woman proclaimed from newspaper, magazine, and drugstore ads. And across America, three out of every ten women dyed their hair blonde. They ate a chalk called Metrecal, instead of food, to shrink to the size of the thin young models. Department-store buyers reported that American women, since 1939, had become three and four sizes smaller.
You have not included which terms were underlined, but nonetheless, we can conclude what issue is presented. This excerpt tells us that, in the eyes of society, women had to look a certain way. They often dyed their hair blonde and followed a certain diet in order to look better. There is nothing about them being content, their careers, or life in show business.
