6. When Mary Warren is asked to faint for the court the way she said she had pretended to in the witchcraft trials, she says she cannot. What is her explanation to Judge Hathorne for her inability to pretend to faint?

From the text:

Mary Warren: I - I cannot tell how, but I did. I - I heard the other girls screaming, and you, Your Honor, you seemed to believe them, and I - It were only sport in the beginning, sir, but then the whole world cried spirits, spirits, and I - I promise you, Mr. Danforth, I only thought I saw them but I did not.
