An example of a(n) double-blind research study would be where an experiment was conducted on caffeine-induced stress when neither the class researchers nor the test subjects knew who received caffeine and who did not until after the study was finished.
<h3>What is double-blind research study?</h3>
- A double-blind study is one in which neither the participants nor the researchers are aware of which group is getting the treatment.
- However, it also prohibits researchers from unintentionally disclosing information about the experiment.
- This type of study is particularly helpful in avoiding biased reports that are likely the result of placebo effects.
- Imagine, for instance, that researchers are looking into the effects of a novel medication.
- The participants in a double-blind study would not be aware of who was receiving the real medication and who was receiving a placebo, and neither would the researchers who contact with them.

Answer:
The idea that the oldest rock will always be the bottom layer of a series of rock layers is called the principle of superposition.
Explanation:
According to the law or principle of superposition, the sequence of layers of sedimentary rock go from the oldest, at the bottom, to the youngest, at the top. Sedimentary rock is formed when pieces of rock and even of living organisms - once they die, of course - are deposited on a surface. As time passes, new pieces are deposited on top of the older pieces. That process happens again and again until we have different layers of sedimentary rock, the first one being the oldest, that is, the one that was first deposited there.
