Three different scientific institutions provide data about how much the annual global temperature has deviated from the norm in the years 1880 to 2014. The norm is based on the temperatures of a base period, from 1951 to 1980. Institution A’s data show that the annual global temperature deviated from the norm by 0.75°C in 2010.
Institution B’s data show that the annual global temperature deviated from the norm by 0.72°C in 2010.
Institution C’s data show that the annual global temperature deviated from the norm by 0.77°C in 2010.

Which are accurate statements about this data? Select the two correct answers.

A. The institutions gathered enough data for scientists to draw a conclusion about whether the annual global temperature is gradually increasing.
B. The data gathered by each institution is very different from the data gathered by the other institutions.
C. The institutions have not yet gathered enough data for scientists to draw a conclusion about whether the annual global temperature is gradually increasing.
D. The data gathered by each institution is very similar to the data gathered by the other institutions.
