Hey guys, I could really use your help. Lots of points and brainly for a good answer.
I just need to determine if these arguments are valid or invalid reasoning.

Valid or Invalid? Women are the main breadwinners in two-thirds of families across the country.
Valid or Invalid? Employers pay different workers different salaries based on skill level.
Valid or Invalid? Paying people different salaries for the same work is discrimination.
Valid or Invalid? Pay discrimination hurts middle class families.
Valid or Invalid? Women are ready to fight back against pay discrimination.
It would also be really helpful if you could explain why, im a bit confused as to the definition of invalid reasoning.
Thanks!

According to a 2019 research, by the Center for American Progress, nearly two-thirds—64.2 percent—of mothers were primary, sole, or co-breadwinners for their families.

Answer 2:

This assertion is equally Valid

Explanation:

Ideally, employers ought to pay different workers different salaries based on skill level.

Ideal situations exist in some organisations. Whilst in orders it doesn't. When this idea of equality and fairness is violated, Human Resource Professionals are often required to solve the problem. Please note that it is possible to have situation where there is a basis for paying workers other than skill.

Answer 3:

This is Valid.

Explanation:

When workers in seemingly identical jobs are paid differently, the employer leaves itself open to claims that the motivation for the different pay is discriminatory—particularly if the person on the lower end of the pay scale is a member of a protected class.

Title VII of the 1964 Civil Rights Act forbids discrimination on grounds of ethnicity, colour, religion, sex and national origin in jobs.

Answer 4:

This assertion is equally valid.

Explanation:

Living in an unequal society creates anxiety and stress about status which can affect ones health. Inequality is strongly associated with helplessness and hopelessness. Communities where peoples right are protected and where there is a system that ensures and protects fairness, experience longevity, are less likely to be mentally ill or obese, and child mortality rates are lower, whether they are middle class or not. Bear in mind, middle class is only a relative approximation.

Answer 5:

This is very valid

Explanation:

I'd say very very valid given that there are plethora of cases involving women fight against inequality of pay.

For instance; Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964.

This was the first attempt at equal pay legislation in the United States, H.R. 5056, "Prohibiting Discrimination in Pay on Account of Sex," was introduced by Congresswoman Winifred C. Stanley of Buffalo, N.Y. on June 19, 1944.

For nearly half a century, the battle for fair pay for women has raged among advocates, celebrities and lawmakers.

Despite America's landmark legislation, women working in the US often face significant obstacles, including a gender-based wage disparity that costs them thousands of dollars a year.

More than 50 years ago, the US passed the Equal Pay Act but American women still face a large gender-based pay disparity.

Cheers!
