Answer:
d. Whether he can conduct the study just as well without deception
Step-by-step explanation:
Dr. Kushner must make the greatest possible effort so that the experiment he is conducting has correct and balanced results, where all variables have been tested in the best possible way. He understands this need and is therefore reflecting on whether to deceive the experiment participants (with a false reason for them to wake up) or to follow the experiment without deception. To decide this, he must ask himself if he will be able to conduct the experiment efficiently without the use of deception, as participants may be unmotivated to wake up if they do not have a fair, even if false, reason for doing so.
