Final answer:
Goody Putnam's role is to seek answers about her deceased children by sending her daughter Ruth to Tituba for supernatural assistance, which is best described by option (a).
Step-by-step explanation:
In Arthur Miller's play, The Crucible, Goody Putnam's role in the situation at Reverend Parris' house is best described by option (a): she sent Ruth to Tituba to get answers about her seven dead babies.
She is deeply troubled by the death of her offspring and turns to what she believes is supernatural assistance to understand these tragedies. This action reflects the overarching theme of hysteria and fear of the unknown, representing the historical context of the Salem witch trials.
It's important to note that Goody Putnam is not motivated by anger towards Parris specifically (option b), nor is she seeking to cause trouble for land (option c), or because of anger at her husband (option d). Her actions are driven by a mother's desperation to make sense of her children's deaths in a society where witchcraft and dealings with the devil are considered possible explanations for such misfortunes.
