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.

Based on the graph, we can conclude that in 1850:
The population was around 100 million and steel consumption began.
To answer this question using the graph, you need to locate the point on the graph corresponding to the year 1850.
First, locate the year 1850 on the horizontal axis. Since the increments are 100 years, count five intervals starting from 1700: 1800, 1900, 2000, 2100, and finally 2200. Therefore, 1850 falls between the interval marked for the year 1800 and the interval marked for the year 1900.
Next, find the corresponding values for both steel consumption and population on the vertical axis at the point you identified.
Based on the given information, the line for population starts at 90 million for 1700 and has a slow growth rate, reaching 120 million by 1900. Therefore, in 1850, the population size can be estimated to be between these two values, around 100 million.
Similarly, the line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. Since 1850 is before the starting point for steel consumption, the value for steel consumption in 1850 can be approximated to be zero or very low.
Putting these two pieces of information together, you can conclude that the population was around 100 million, while steel consumption was either very low or zero in 1850.
Therefore, the correct answer is: The population was around 100 million, and steel consumption began.
