Answer:
inspired
Step-by-step explanation:
After reading this paragraph we can say that the tone being used is an inspired one. This is because the entire paragraph is highlighting all of the wonderful aspects of the 1800's in the United States, including all of the innovations, discoveries, and artistry. The paragraph even mentioned the names of many of the most influential writers of that time period. It however does not mention any negatives regarding that time period. Therefore, it is being biased which usually happens when the tone is meant to be inspired.
