Passage II
When a 13-lined ground squirrel (a mammal) hibernates, it does not eat, and it alternates between periods of torpor (characterized by a reduced rate of metabolism, low body temperature, and little movement) and active bouts (characterized by a normal rate of metabolism, normal body temperature, and normal movement). Figure 1 shows the body temperature of a 13-lined ground squirrel during 12 consecutive months, including several months of hibernation. Figure 2 shows the average total blood cholesterol of a group of 13-lined ground squirrels at various times during the same 12 months.

12. Consider the blood samples having an average total cholesterol of 420 mg/dL, as shown in Figure 2. Based on Figure 1, were those blood samples collected when the 13-lined ground squirrels were hibernating?
Your Answer is
Correct Answer is F
Explanation
The condition given in the question stem is average total cholesterol of 420 mg/dL, and the active bout is located in Figure 2; the active bouts in Figure 1 belong to the hibernation period, so choose F
