Passage I
In a study of fur pigmentation in deer mice, Peromyscus polionotus, scientists compared the brightness of the fur of mice from populations located different distance directly inland from a coastal site. Figure 1 shows 2 facial regions and the 2 body regions at which the fur of each mouse was evaluated (on a scale from 0 to 1.00) with respect to its brightness. Figure 1 also shows how, for each of the 4 regions, average relative brightness varied with inland distance.
Figure 2 shows how the average brightness of surface soil samples, given as the average percent relative reflectance, varied with inland distance.
2. According to Figure 1, the average relative brightness of the dorsal stripe was 0.25 at an inland distance that was closest to which of the following?
Your Answer is
Correct Answer is H
Explanation
Look at the upper right dorsal stripe in figure 1, when the vertical coordinate is 0.25, the horizontal coordinate is about 60
