Question
Use the graph to answer the question.
The vertical axis is labeled millions and ranges from 0 to 900 in increments of 100. The horizontal axis is labeled year and lists dates from 1700 to 2000 in 100-year increments. The line for population starts at 90 million for 1700 and with a slow growth rate reaches to 120 million by 1900. The line then rises with a high growth rate and reaches beyond 600 million by 2000. The line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. The line then rises with a high growth rate to reach beyond 800 million by 2000. The values used in the description are approximate.

More building construction is needed to provide for the needs of people.
The increase in steel consumption seen on the graph was primarily due to more building construction being needed to provide for the needs of people.
To answer this question, we need to analyze the information provided in the graph. The graph displays the population and steel consumption over time.
From the graph, we observe that the population line shows a slow growth rate from 1700 to 1900, reaching 120 million. However, after 1900, the population line rises with a high growth rate, exceeding 600 million by 2000.
The steel consumption line, on the other hand, starts from 0 in 1860 and reaches 20 million by 1900. After 1900, the steel consumption line also rises with a high growth rate, surpassing 800 million by 2000.
Based on this information, we can conclude that the increase in steel consumption is primarily due to the fact that more building construction is needed to provide for the needs of the growing population. As the population increased, more infrastructure such as buildings, bridges, and roads would need to be constructed, which requires significant amounts of steel.
Therefore, the correct answer to the question is:
More building construction is needed to provide for the needs of people.
