A.The powder is an unnatural substance
Answer:
B. social
Explanation:
The excerpt represents a social letter. We can come to this conclusion because the letter has a friendly and easy-to-understand language that retains the "Mr" and "Mrs" titles, which shows that the letter is not informal. Also, the author of the letter is thanking the hospitality of Mr. and Mrs. Brothers and not dealing with business, this shows that this is not a business letter.
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>
The author's thesis in the text is that President Roosevelt was very effective in helping people throughout the Great Depression through a series of programs.
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.
