Hey guys, I could really use your help. Lots of points and 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!

Read the excerpt below and answer the question. "you just don't understand," she said, as maggie and i came out to the car. "what don't i understand? " i wanted to know. "your heritage," she said, and then she turned to maggie, kissed her, and said, "you ought to try to make something of yourself, too, maggie. it's really a new day for us. but from the way you and mama still live you'd never know it." in the excerpt above, what can the reader infer about dee's opinion of her sister? she admires maggie for preserving the family traditions. she feels superior to maggie because she is uneducated. she feels sorry for maggie because of her poverty. she respects maggie because of her resilience.
