Answer:

  b. The break in the vertical axis.

Step-by-step explanation:

You want to know what about the given bar graph gives the impression that one group has twice as many endangered species as mammals.

Vertical axis

An impression of the relationship between graphed values is given by the visual appearance of the graph. This graph will show mammals with a bar that is about 1.2 grid squares high, while birds and fish will have bars that are 5 and 4 grid squares high, respectively.

These bar heights give the impression that fish and birds have about 3 and 4 times the number of endangered species as mammals, respectively. The actual ratios are much smaller.

The erroneous impression is given by the break in the vertical axis, choice B.
