Answer 2

Hi,

"bachelor" should be changed to "Bachelor's degree"

"without degree" should be changed to "without a college degree"

"This situation makes your employees low-income families" should be changed to "This situation forces your employees to raise low-income families or very low-income families"

Answer 3

"strong" is not a needed adjective here.

Your employees have the knowledge and skills necessary to grow the company.
