ACT Science OG Test 1 - Passage I

Questions 1-6 are based on the following passage.

In a study of fur pigmentation in deer mice, Peromyscus polionotus, scientists compared the brightness of the fur of mice from populations located different dis­tances directly inland from a coastal site. Figure 1 shows
the 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.

*For each facial or body region, the darkest fur pigmentation was assigned a brightness value of 0, and the lightest fur pigmentation was assigned a brightness value of 1.00.
Figure 2 shows how the average brightness of surface soil samples, given as the average percent relative reflectance, varied with inland distance.
