The correct answer is C. A great increase in steel production and an increase in the value of manufactured goods
Explanation:
The Gilded Age in the U.S. refers to a historical period from 1870 to 1900 in which the economy of the country grew massively in comparison to other historical periods. This happened as industrialization expanded greatly as a result of millions of immigrants that arrive in the country and increased the labor force in the country and the use of more advanced technology in factories, farms, and other economic areas. As a result of this, the production of many products increased including tobacco, steel manufacturing, and coal mining as there were more workers and technology, additionally, the value of manufactured goods also increased as the products during this age were better in quality and manufactured in a shorter time than those from other countries, which made the U.S. one of the strongest economy in the world during the Gilden Age. Thus, the two factors that caused the massive economy grew during the Gilden Age was an increase in both steel production and the value of manufactured goods.
