What led to the increase in steel consumption?

A - steel consumption increased when more people started to use computers
B - Fossil fuels that became popular depends on steel production
C - More people started mining steel that are sold outside of the country
D - More building construction is needed to provide for the people

To determine the answer to this question, we need to evaluate each option and consider which one best explains the increase in steel consumption:

A - steel consumption increased when more people started to use computers: This option implies that the increase in steel consumption is directly related to the use of computers. However, while computers do require steel components, their overall impact on steel consumption is relatively small compared to other factors.

B - Fossil fuels that became popular depend on steel production: This option suggests that the popularity of fossil fuels is linked to steel production, leading to an increase in steel consumption. It is worth noting that steel is used extensively in the production and infrastructure of the fossil fuel industry, such as pipelines and oil rigs. Therefore, this option is a plausible explanation.

C - More people started mining steel that is sold outside of the country: This option states that an increase in steel consumption is driven by more people mining steel for international sales. However, steel is typically produced through the extraction of iron ore, not through direct mining of the end product itself. Therefore, this option is less likely to explain the increase in steel consumption.

D - More building construction is needed to provide for the people: This option suggests that the demand for building construction has led to an increase in steel consumption. Buildings often utilize steel in their construction, reinforcing structures and providing support. Therefore, this option is a plausible explanation.

Considering the options presented, option B (Fossil fuels that became popular depend on steel production) and option D (More building construction is needed to provide for the people) both offer reasonable explanations for the increase in steel consumption. Without further context or additional information, it is difficult to determine which one is the correct answer.
