How does Bly alter her behavior to convince Mrs. Stanard, Tom Bockert, and the officers that she is mentally ill? Cite textual evidence from the selection to support your answer.

To convince people that he was mentally ill, Bly trained strange facial expressions, stayed at an inn, and started saying he was afraid of the guests, saying that he would not sleep in fear of the crazy ones. The other day, she stated that she didn't remember any of this and that she had amnesia.

According to the context of her question, we can assume that you are referring to the text "Ten Days in a Mad-House."

This text was written by Nellie Bly and when we read it, we can see that:

Bly was a journalist and wanted to expose the brutality and neglect to which women were subjected at the Lunatic Women's Asylum on Roosevelt Island.
To be able to do this, Bly needed to pretend she was crazy so she would have access to the treatments that this asylum presented.
To pretend she was crazy, Bly stayed at a women's boarding house.
In that boarding house, she started making weird facial expressions, which she had rehearsed.
She spent the night screaming that she couldn't sleep because she was scared of the crazy ones.
She claimed that the other guests had looked crazy.
The other day she was taken to court and stated that she didn't remember anything she did because she had amnesia.

That was enough for her to be declared insane and committed to the asylum.

Several doctors examined her and although Bly was not crazy and behaved normally, she was declared "completely insane" and was subjected to terrible treatments, abusive employees, spoiled food, and a dirty and pest-ridden environment.

Bly denounced all of these things through his book, which caused a huge change in nursing homes across the country.
