Why isn't (B) sufficient by its self? The problem stem states the number of Democrats and Republicans who voted and (B) states the % of Democrats and Republicans who are women who voted for the Resolution

We have 4800 total voters.
1800 were Democrats, and 3000 were Republicans.
(2) tells us that 1/3 *of the dems who voted FOR Resolution K* (not total dems) and 1/2 of the dems who voted in favor of Res K (again, not all rep's) were females.
Unfortunately, we don't know if 3 democrats voted for the resolution, or 300, or 1500... Same goes for republicans...

Make sense?
