The graph shows records of temperature (light gray line) and CO 2 (dark gray line) over the past 1,000 years. CO 2 is recorded in parts per million (ppm).
-If you focus on the data from the mid-1900s (indicated by the arrow) through today, the graph shows that
A) there is a correlation between CO2 and temperature; when CO2 levels are high, so is temperature.
B) there is a correlation between CO2 and temperature; when CO2 levels are high, temperature is low.
C) there is no correlation between CO2 and temperature; CO2 fluctuates randomly and temperature is constant.
D) there is no correlation between CO2 and temperature; CO2 is constant and temperature fluctuates randomly.

Quizplus · Accepted Answer

The paragraph states that there is a correlation between CO2 and temperature and that when CO2 levels are high, so is temperature. This is shown in the graph for the mid-1900s through today.
