Final answer:
Brayden's summary is missing the significant mention of the Equal Rights Amendment, which was central to combatting gender discrimination legally, and despite its widespread initial support, did not pass by the 1982 deadline.
Step-by-step explanation:
Brayden’s summary of Chisholm’s speech "For the Equal Rights Amendment” is missing a significant detail regarding the historical context of the fight for women's rights. A critical detail to add would be the mention of the Equal Rights Amendment (ERA) which was a proposed amendment to the US Constitution stating that equality of rights under the law shall not be denied on the basis of sex. This inclusion would provide a clearer understanding of Chisholm’s address in the broader landscape of legislative efforts to combat gender discrimination and achieve legal equality for women. Additionally, it's important to reference that the ERA, despite its initial fast-paced ratification process, was ultimately not passed by the required number of states by the 1982 deadline.
