what did antiquities act of 1906 accomplish a. it established national parks b. it strengthened railraod regulations c. it regulated the meatpacking idustry d. it ended rate discrimination by railroads

The correct answer is:

a. It established national parks

The Antiquities Act of 1906 was signed into law by President Theodore Roosevelt. Its main purpose was to protect and preserve significant archaeological sites, historic structures, and objects of historic or scientific interest on federal lands.

The act granted the President the authority to establish national monuments by proclamation, without the need for congressional approval. This allowed the President to quickly protect important areas from development, looting, and destruction.

The Act was instrumental in the creation of many national parks and monuments that we know today, including the Grand Canyon National Park, Olympic National Park, and Devils Tower National Monument, among others.
