Answer:
When it comes to satire, Shaw is saying that women feel threatened in the presence of other young and attractive women, because it arouses in men a desire for freedom from their marriages.
Step-by-step explanation:
"The Girls in Their Summer Dresses" shows a couple who had planned a happy and friendly weekend between the two, but have their plans canceled due to an argument that is established between them. This discussion begins when the husband looks with admiration at other young and attractive women, which makes his wife sad and insecure. She says she doesn't want him to do this, she feels betrayed and doesn't want to lose her husband. He says he never cheated on her, although he can't help looking at attractive women.
As a satire, the author portrays young and beautiful women as threats to other women. It is as if the author showed that married women feel insecure about their power of attraction in relation to their husbands, who end up desiring and admiring other women.
