Final answer:
The 'Washington Wives' responded by having their politician husbands call congressional hearings on their concerns. The PMRC demanded a rating system and lyric disclosure in music recordings and took actions to influence music regulation.
Step-by-step explanation:
The 'Washington Wives' responded to the RIAA's attempt to compromise with the PMRC by having their politician husbands call congressional hearings on their concerns. They demanded a rating system for music recordings and the publication of all lyrics to new releases.
The PMRC, which comprised primarily of wives of Washington D.C. politicians, took actions to influence music regulation such as producing a list of offensive recordings and advocating for labels on recordings. These actions led to hearings in the Senate on the issue.
