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.

The population was around 100 million and steel consumption began.
Steel consumption was around 100 million and the population was beginning to grow.
The correct answer is: The population was around 100 million and steel consumption began.
The correct answer is: The population was around 100 million and steel consumption began.
To answer this question using the graph, we need to find the point on the graph that corresponds to the year 1850. Since the horizontal axis lists dates in 100-year increments, we know that 1850 falls halfway between the years 1800 and 1900.
By looking at the line for population, we can see that in 1800 the population was around 90 million, and in 1900 it had grown to around 120 million. Since 1850 is halfway between these two years, we can estimate that the population size would be closer to the midpoint, which is around 105 million.
Now let's look at the line for steel consumption. We know that in 1900, the steel consumption was around 20 million. Since 1850 is closer to 1900 than to the starting point of the line (1860), we can estimate that the steel consumption in 1850 would be closer to the value in 1900, which is around 20 million.
Therefore, we can conclude that in 1850, the population size was around 105 million and the steel consumption was around 20 million.
The correct answer is: The population was around 100 million and steel consumption began.
