Question

which of these did townsend advocate for and include in the social security act of 1935?
requirements for the spending of stipends within the us
financial assistance for people with physical disabilities
monthly financial assistance for retired americans
the creation of a sales tax to fund stipends of retirees

Explanation:

The Townsend Plan advocated for monthly financial assistance for retired Americans, and this concept influenced the Social Security Act of 1935. The other options: requirements for spending stipends within the US was part of Townsend's plan but not included in the 1935 Act as is; financial assistance for disabled people was added later, not in 1935; and a sales tax to fund retiree stipends was not part of the 1935 Act's funding (it used payroll taxes). So the correct one is the option about monthly financial assistance for retired Americans.

Answer:

monthly financial assistance for retired Americans
