Passage
Researchers conducted trials on a certain prescription drug delivered in immediate-release capsules and extended-release capsules.
Figure 1 shows the mean concentration (nanograms per milliliter [ng/mL]) of the two active ingredients of the prescription drug in patients’ blood plasma over time (hr).

In clinical trials of the prescription drug, subjects given the prescription drug were interviewed at regular intervals about the symptoms the prescription drug is meant to relieve.
After each interview, the subjects were assigned a symptom score. A high symptom score corresponds to high intensity of symptoms, and a low symptom score indicates low intensity of symptoms. Figure 2 shows the mean symptom score over time (hr) for subjects who took the prescription drug.
In the clinical trials, some subjects were given the prescription drug and some subjects were given a placebo (an inactive pill). Table 1 shows the percentage of subjects from both groups who reported various adverse side effects.

Q. According to Figure 1, 16 hours after taking the extended-release form of the prescription drug, the difference in mean blood plasma concentration between Ingredient A and Ingredient B is closest to:
  • a)
    7 ng/ml.
  • b)
    9 ng/ml.
  • c)
    11 ng/ml.
  • d)
    16 ng/ml.
Correct answer is option 'C'. Can you explain this answer?

The point at hr = 16 for the “Ingredient A extended-release” line is at about 15 on the vertical axis. The point at hr = 16 for the “Ingredient B extended-release” line is at about 4 on the vertical axis. Therefore, the difference is about 11.
