B - CORRECT ANSWER - A medical scientist is designing an experiment to test the results
of a new drug that she hypothesizes will greatly reduce and possibly eliminate the side effects of
a new cancer treatment. If this experiment is to be set up correctly, she must
A. divide the patients into two groups and give one group the new drug and give the other group
nothing.
B. divide the patients into two groups and give one group the new drug and the other group a
drug that has no effect (for example, a tablet that only contains sugar).
C. divide the patients into two groups and give each group the same amount of the new drug
D. divide the patients into two groups and give one group one-half of the dosage of the new drug
