Theodore roosevelt is often called a "progressive" president. which of these would best be an example of this label?
a) his refusal to seek a third term as president
b) he backed the construction of the panama canal
c) his support of "banana republics" in latin american.
d) he supported passage of the food and drug act of 1906

The answer would be D. Firstly,
Roosevelt was the founder of the progressive platform in 1912 and one thing that he tried to accomplish through this platform was to serve the interest of the public by creating more programs that pertained to factors like initiating social insurance and limiting work hours. Also in order to accomplish this, Roosevelt implemented regulations upon institutions such as big bussiness. One example in relation to your question would be the Food and Drug Act of 1906 which was designed to make sure food monolpies weren't providing food or drug products that were hinderous to human health and it also established that these companies had to utilize correct labels on their products. Thereby, because the Food and drug act of 1906 was one of many attempts from Theodore Roosevelt to regulate certain intuitions in order to enhance the lives of the American citizens, Letter D is the answer. I hope this helps you out!
