Consider the following scenario. Use your knowledge about scientific evidence to answer the question that follows.
Concrete, used in sidewalks, is composed of three substances: cement, an aggregate (like sand), and water. When mixed together, these three substances produce a reaction in which calcium ions are formed. The product of this chemical reaction is what is known as concrete. Each time you perform this experiment, you get the same result. Which of the following statements describe the results produced by this experiment?
a. The results provide evidence that rests on an argument from authority.
b. The results provide anecdotal evidence.
c. The results provide empirical evidence derived from observations of the natural world.
d. The results provide evidence that is replicable, or repeatable, in future experiments.

Answer:

D

Explanation:

If these three substances are mixed together with the required proportion, it would yield concrete all the time. Thus, the result is replicable, or repeatable, in future experiments.

The result is not from an observation of the natural world because the three substances were mixed together by man in a lab.
