Answer:
d. by developing a less expensive process for turning iron into steel
Explanation:
Henry Bessemer was an engineer, foundry of types of printing, pioneer of the modern iron and steel industry, and inventor of the steel refining process that bears his name (the Bessemer Process, which is applied in the Thomas-Bessemer furnaces of the steel industry).
During the Crimean War he invented a very effective artillery projectile, however military technicians reported that the cast iron cannons of the time were not able to withstand the force of this new projectile.
Bessemer focused on resolving the issue and thus, in 1855, he patented a process of refining and reducing iron to produce steel in industrial quantities at low cost. The procedure was to blow pressurized air into the bottom of the ladle where the pig iron was being poured. The air reacts its oxygen with silicon, then carbon, followed by phosphorus, which are iron impurities in the foundry. The reaction of oxygen and silicon is highly exothermic, which made the metal continue melting without spending more fuel. The air is injected under pressure through the bottom of the container that has the shape of an open spoon, and stops until a red flame arises, which indicates the oxidation of the iron.
Over time the open spoon was replaced by the open oval spoon on the upper surface, mechanism still known as Bessemer converter. Currently the Bessemer process is in decline replaced by his heirs; Linde or LD processes of blowing pure oxygen pressure.
The impact of this invention, in the context of the Industrial Revolution, was immense. While the heavy industry was shipyards, railways, manufacturing machinery ...) an abundant and cheap raw material was achieved. The steel that was now available in large quantities made other achievements feasible. Thanks to Bessemer it was possible to see bigger, better and cheaper steel ships, bridges, major railways, skyscrapers, etc. In other words, everything that characterized the 19th century as the driving force of the 20th century.

the same wages as men
lower wages than men
in material goods and foodstuffs
The correct answer is "lower wages than men".
The industrial revolution started in Great Britain in the second part of the 18th century. This concept rapidly spread throughout the world and many countries adopted the same model for development. As improvements in manufacturing methods from diverse industries occurred, machines started to gradually replace workers. This made laid the possibility of hiring less skilled workers, as machines were already doing the complex tasks. Business owners started to hire women and children. This was a win-win situation for both parts, as women saw the chance of earning higher wages in comparison to doing housework. However, the salary gap was very noticeable between both genders during that time.

The correct answer is the following: option A. The Cumberland Road was significant because it was the first road constructed using federal funds. The Cumberland Road, also known as the National Road, was the first major improved highway in the United States that was built by the federal government, using federal funds.
Built between 1811 and 1837, the highway went from Cumberland, Maryland all the way to Vandalia Illinois. From 1833, various sections of the road became the financial responsibility of the states in which they were situated, and under this circumstance, the use of the Cumberland Road, no longer was free, but became subject to state imposed tolls.
