Final answer:
The text of "The Crucible" does not provide clear evidence on whether Mary Warren knew how the poppet she gave Elizabeth Proctor would be used, thus the answer cannot be determined.
Therefore, the correct answer is 3) Cannot be determined.
Step-by-step explanation:
The question is whether Mary Warren knew how the poppet she gave Elizabeth would be used. In Arthur Miller's play "The Crucible", Mary Warren gives Elizabeth Proctor a poppet (a small doll) that she made in court. Later on, this poppet is used as evidence against Elizabeth when Abigail Williams accuses her of witchcraft, stating that a needle found in the poppet's belly is proof of Elizabeth's supernatural harm against her.
However, the text does not provide explicit evidence whether Mary Warren intentionally used the poppet as part of the setup or if she was unaware of how it would be used.
Therefore, the correct answer is 3) Cannot be determined.
