Answer: A
Step-by-step explanation:
There was no active ingredient in the pill but Jennifer thought her headache went away . This is what is required for a placebo effect.
The benefit is due to the fact that Jennifer was given the treatment (pill, although only a sugar pill) and not an effect of the "active ingredient" (headache medicine).
- Jennifer will think that she is taking medicine and will get satisfy after having it.
What is placebo effect?
- The placebo effect is when a person's physical or mental health appears to improve after taking a placebo or dummy treatment.
- The effects of the active drug or other intervention are compared to the effects of the placebo.
- Even though a placebo has no active ingredients to cause a positive effect, it can still make a patient feel better.
