Question

According to the line graph above, between which two consecutive years was there the greatest change in the number of 3&#8209;D movies released?

Accepted Answer

Choice D is correct. The change in the number of 3-D movies released between any two consecutive years can be found by first estimating the number of 3-D movies released for each of the two years and then finding the positive difference between these two estimates. Between 2003 and 2004, this change is approximately movies; between 2008 and 2009, this change is approximately movies; between 2009 and 2010, this change is approximately movies; and between 2010 and 2011, this change is approximately movies. Therefore, of the pairs of consecutive years in the choices, the greatest increase in the number of 3-D movies released occurred during the time period between 2010 and 2011. Choices A, B, and C are incorrect. Between 2010 and 2011, approximately 20 more 3-D movies were released. The change in the number of 3-D movies released between any of the other pairs of consecutive years is significantly smaller than 20.
