"Delighted" is a term used to express great pleasure or happiness, and it may not necessarily be accurate to describe the entire period of the late 1800s as such. However, it is true that many significant advancements and achievements were made during this time, particularly in the fields of science, technology, and industry, which may have brought about positive changes and improvements in people's lives. Some examples include the invention of the telephone, electric lighting, and the automobile, as well as the evolution of modern medicine and the expansion of the railroad and telegraph systems. Additionally, there was a growing sense of nationalism and optimism in many countries, including the United States and Europe, which contributed to a sense of progress and prosperity. However, it is important to note that this period also had its share of challenges and disparities, including widespread poverty, social inequality, and political instability.
