excerpt from "Why Equal Pay Is Worth Fighting For" by Senator Elizabeth Warren, April 17, 2014

I honestly can't believe that we're still arguing over equal pay in 2014.

When I started teaching elementary school after college, the public school district didn't hide the fact that it had two pay scales: one for men and one for women. Women have made incredible strides since then. But 40 years later, we're still debating equal pay for equal work.

Women today still earn only 77 cents for every dollar a man earns, and they're taking a hit in nearly every occupation. Bloomberg analyzed Census data and found that median earnings for women were lower than those for men in 264 of 265 major occupation categories. In 99.6 percent of occupations, men get paid more than women. That's not an accident; that's discrimination.

The effects of this discrimination are real, and they are long lasting. Today, more young women go to college than men, but unequal pay makes it harder for them to pay back student loans. Pay inequality also means a tougher retirement for women. . . .

For middle-class families today, it usually takes two incomes to get by, and many families depend as much on Mom's salary as they do on Dad's, if not more. Women are the main breadwinners, or joint breadwinners, in two-thirds of the families across the country, and pay discrimination makes it that much harder for these families to stay afloat.

Women are ready to fight back against pay discrimination, but it's not easy. Today, a woman can get fired for asking the guy across the hall how much money he makes. Here in the Senate, Sen. Barbara Mikulski (D-Md.) introduced the Paycheck Fairness Act to give women the tools to combat wage discrimination. It would help ensure that salary differences have something to do with the actual job that they are doing, and not just because they are women.

This is a common-sense proposal—no discrimination, no retaliation when women ask how much the guys are getting paid, and basic data that tell us how much men and women are getting paid for key jobs. Basic protection, basic information—that's essentially all this bill does. Employers can still pay different workers different salaries based on factors like skill, performance, expertise, seniority, and so forth—the Paycheck Fairness Act doesn't touch any of that.

Even while women still earn less than men in 99.6 percent of occupations, Senate Republicans won't even let the Senate vote on a bill to help make the workplace a little fairer for women. They just filibustered the Paycheck Fairness Act for a third time, telling women that we don't need paycheck fairness.

This should be a no-brainer. America's women are tired of hearing that pay inequality isn't real. We're tired of hearing that it is somehow our fault, and we're ready to fight back. We are not going to give up on passing the Paycheck Fairness Act to level the playing field for hardworking women in the workplace.

Which points from the passage provide valid support for Warren's argument that wage discrimination negatively affects women?

Select Valid Reasoning for points that support her argument. Select Invalid Reasoning for points that fail to support her argument.

Valid Reasoning Invalid Reasoning

Women today still earn a third less of every dollar a man earns.
The Paycheck Fairness Act would ensure that differences in salaries are based on differences in jobs.
More women go to college than men, but unequal pay makes it harder for women to pay back student loans.
Members of the Senate have repeatedly blocked voting on the Paycheck Fairness Act.
More middle-class families rely on two incomes for survival.

Answer 22

Women today still earn a third less of every dollar a man earns. (77 cents is not a third less, a third less would be 66 cents, so not valid)

everything else is mentioned + true, so I would say valid for everything else

Drag the claim that best supports each of Warren's arguments into the correct box.

Pay inequality exists in every job field. ________________

Wage inequity affects families, too. _________________

Women face many obstacles in fighting for equal pay. _______________


''For middle-class families today, it usually takes two incomes to get by.""

''Basic, protection, basic information - that's essentially all this bill does.''

''Women are tired of hearing that pay inequality isn't real. We're tired of hearing that is somehow our fault.''

''In 99.6 percent of occupations, men get paid more than women.''

Answer 24

"Pay inequality exists in every job field. " is best supported by "''In 99.6 percent of occupations, men get paid more than women.''" since this describes how most jobs pay men more than women

"Wage inequity affects families, too. " --> ''For middle-class families today, it usually takes two incomes to get by."" since this is the only quote that says anything about families

"Women face many obstacles in fighting for equal pay." -->
''Women are tired of hearing that pay inequality isn't real. We're tired of hearing that is somehow our fault.'' talks about how people don't believe the wage gap, etc.

Answer 25

also can we close this and move these questions to english since this is technically english not math

Answer 26

ok
