Final answer:
The progressive reforms of the early 1900s included conservation efforts leading to national parks, new federal laws for food safety, and labor laws. The correct options describing these reforms are the creation of national parks and the establishment of laws to ensure food safety.
Step-by-step explanation:
The progressive reforms of the early 1900s had a significant impact on American society. Among these reforms were:
Conservation efforts that led to the creation of national parks.
New federal laws that were passed to monitor diseased, spoiled, and rotten foods, such as the Meat Inspection Act and the Pure Food and Drug Act.
Labor laws that aimed to establish a 10-hour workday and set a minimum wage. However, the notable legislation in this period was the Adamson Act which put in place the first federally mandated eight-hour workday for railroad workers, not specifically a 10-hour workday across all sectors.
Additionally, the 19th Amendment, rather than the 14th, granted women the right to vote, and this was ratified later, in 1920, and not during the early 1900s. African American men were granted the right to vote by the 15th Amendment, which was ratified after the Civil War in 1870, not during the Progressive Era.
The correct options that describe the progressive reforms of the early 1900s are:
Conservation efforts led to the creation of national parks.
New federal laws were passed to monitor diseased, spoiled, and rotten foods.
