After reading the text and identifying the sentences that support the author thesis, we can say they are the following:
"The <u>WPA</u>, which existed until 1943, provided work and a paycheck to almost 9 million Americans."
"At a time when people had lost much - if not all - of the money for which they had worked, The <u>Social Security Act</u> guaranteed pensions to millions of Americans.
<h3>Supporting the thesis</h3>

Sentences that support that thesis will show how the programs functioned, how they helped people. That is why the sentences that mention the <u>WPA </u>and the <u>Social Security Act </u>should be selected. They explain what the two programs did and how people were helped through them.
