How would you explain what a placebo is and why it is used if a trial participant asks you to explain it?

"I would explain to the participant that a placebo is an inactive pill, liquid, or powder with no treatment value. I will further explain that in a placebo-controlled trial, some portion of the participants will receive a placebo instead of an active drug or experimental treatment to assess the experimental treatment's effectiveness and safety versus no treatment at all."

"I will tell the participant that a placebo is a liquid, powder, or pill that has no treatment value used in clinical trials to help determine the difference between the active drug or experiment compared to no treatment at all."
