Answer: D. Women's perspectives would be a way for Congress members to reflect on their actions in order to change them.
Step-by-step explanation:
The effect of Smith's mentioning of women play in supporting her purpose is that "women's perspectives would be a way for Congress members to reflect on their actions in order to change them".
This can be deduced from the excerpt when he said that he wondered how the females feel about the way in which members of their families have been politically mangled in the Senate debate.
Therefore, their perspectives could be a way for the Senate to have a rethink and then change.
