Why is an ABN important to prevent fraud and abuse

Explanation:

The ABN helps to prevent fraud and abuse because if the waiver is not signed before the services are provided and Medicare denies coverage, it makes it look like the provider is providing free services to Medicare patients, and this is considered fraud.

C. Removing control of their labor and their sense of independence.

Explanation:

Before industrial manufacturing became the norm, skilled tradesmen worked in small-scale shops, had a lot of control over their labor, and had a sense of independence.

After industrial manufacturing, many skilled tradesmen went bankrupt because they could not compete with factories, neither in quantity of products made and sold, nor in the price that they could offer. Many of them had to abandom their shops and became industrial workers themselves, losing their autonomy and independence.
