Question

ook at the line graph below, showing world grain production from 1950 to 2010.

A line graph titled Total World Grain Production, 1950 to 2010. The x axis shows years, from 1950 to 2010, and the y axis shows million tons produced, from 0 to 2,500. The line starts at 600 in 1950, 70 in 1960, 1,000 in 1970, 1,400 in 1980, 1,800 in 1990, 1,800 in 2000, 2,200 in 2010.

Which of the following statements about this graph is accurate?

World grain production has increased in every year since 1950.
The amount of grain grown between 1950 and 1980 decreased.
World grain production has generally increased between 1950 and 2010.
More grain was grown in 1950 than in any other year.

Answer 1

Correct answer: "World grain production has generally increased between 1950 and 2010."

Reason: the production rises from about 600 million tons in 1950 to about 2,200 million tons in 2010 (with increases most decades and a plateau around 1990–2000). The other options are false: it did not increase every single year (e.g., it is flat 1990–2000), it did not decrease between 1950 and 1980, and 1950 is not the highest year.
