<span>Women are the main breadwinners in two-thirds of families across the country. - Valid reasoning. This does support the argument by showing the damage the unequal pay does not only to those women, but also to their families.
</span><span>Employers pay different workers different salaries based on skill level. - Invalid reasoning. Women don't demand to be paid more than the men who happen to have better skills, but simply to be paid equally when they have equal skills.
</span><span>Paying people different salaries for the same work is discrimination. - Valid reasoning. That is the basic argument, leveled up. It would be the same as paying all blue-haired men more than the brown or black-haired, when they are doing the same work, with the same skills.
</span><span>Women's incomes are needed for the survival of their families. - Valid reasoning. Just like in the first case, this one shows that this issue doesn't only concern women, but their families - finally, their husbands, the very ones who are paid better for equal work.
</span><span><span>Women are ready to fight back against pay discrimination. - Invalid reasoning. This doesn't have anything to do with the issue itself. It is just a reaction to it, but it doesn't support it.</span>

D. Because it's asking something that requires more than a simple yes or no.
Hello!
The Gettysburg Address mentions the Declaration stating that all men are created equal. During Lincoln’s time that was needed because many people became slaves based on their background, race, or culture.
A common theme is that all men are created equal.
Hope this helps!
