Answer:
the students have been informed they will receive something, but NOT which it is
Explanation:
Based on the information provided within the question it can be said that by signing the informed consent to participate form they have proof that the students have been informed they will receive something, but NOT which it is. Whether it is the actual medical treatment or the placebo, they will not know which it is, only the researchers will have access to that information.
