Journalist: Recent studies have demonstrated that a regular smoker who has just smoked a cigarette will typically display significantly better short-term memory skills than a nonsmoker, whether or not the nonsmoker has also just smoked a cigarette for the purposes of the study. Moreover, the majority of those smokers who exhibit this superiority in short-term memory skills will do so for at least eight hours after having last smoked.

Question: If the journalist's statements are true, then each of the following could be true EXCEPT:
Options:
A. The short-term memory skills exhibited by a nonsmoker who has just smoked a cigarette are usually substantially worse than the short-term memory skills exhibited by a nonsmoker who has not recently smoked a cigarette.
B. The short-term memory skills exhibited by a nonsmoker who has just smoked a cigarette are typically superior to those exhibited by a regular smoker who has just smoked a cigarette.
C. The short-term memory skills exhibited by a nonsmoker who has just smoked a cigarette are typically superior to those exhibited by a regular smoker who has not smoked for more than eight hours.
D. A regular smoker who, immediately after smoking a cigarette, exhibits short-term memory skills no better than those typically exhibited by a nonsmoker is nevertheless likely to exhibit superior short-term memory skills in the hours following a period of heavy smoking.
E. The short-term memory skills exhibited by a regular smoker who last smoked a cigarette five hours ago are typically superior to those exhibited by a regular smoker who has just smoked a cigarette.
