In 4-5 sentences, explain how life in cities improved in the late 1800s and early 1900s. Focus on how innovations in public transportation and travel as well as how technology helped solve some of the problems of crowding.

During the late 1800s and early 1900s, life in cities improved significantly with the introduction of public transportation systems such as electric trolleys and subway systems. These innovations made it easier for people to move around the city quickly and efficiently, reducing congestion on the streets. Additionally, advances in technology such as the development of skyscrapers allowed for more efficient use of limited space, leading to taller buildings and increased housing options for city dwellers. Sanitation and public health also improved during this time with the advent of sewage systems, clean water supplies, and better waste management practices, reducing the spread of disease and improving overall quality of life in urban areas.
