Answer:
In the short story "The Stolen Party" by Liliana Heker, there are several instances where it is implied that Rosaura's mother does not approve of her daughter attending the party. One example of text evidence to support this idea is when Rosaura tells her mother that she has been invited to the party, and her mother responds by saying, "I don't like you going, it's a rich people's party" (paragraph 4). This statement indicates that Rosaura's mother has concerns about her daughter attending a party where she may not fit in because of her social status.
Another example of text evidence to support this idea is when Rosaura's mother is getting her ready for the party and tells her to wear her "good dress" (paragraph 13). This suggests that Rosaura's mother wants her daughter to look presentable and make a good impression at the party, which could be seen as a way of trying to fit in with the wealthier guests.
Finally, at the end of the story, when Rosaura is upset about not receiving a party favor like the other guests, her mother says, "I told you it was a bad idea to go. I knew it would end badly" (paragraph 66). This statement shows that Rosaura's mother had concerns about her daughter attending the party from the beginning, and that she ultimately feels vindicated in her fears when Rosaura is disappointed. All of these instances of text evidence support the idea that Rosaura's mother does not approve of her daughter attending the party.
