Answer to Question 1

C
A true clinical trial is blinded when the subjects in the trial do not know whether they are receiving the active treatment or a placebo treatment. Placebo treatments are thought to have no specific effect on the expected outcome.

Answer to Question 2

C
Sleep terrors are related parasomnia in which there is no recall of the sleep-related event. Individuals experiencing sleep terrors rouse suddenly from sleep with a cry or scream. They typically sit up in bed in apparent terror; sweaty, pupils dilated, tachypneic, and tachycardic.
