I believe the answer is: C. federal system.
In a federal system, the central government granted each states the freedom to govern themselves as long as they do it within the scope of legislature that created by the central government.

Answer:
Dr. Ingram conducted an C. experimental study.
Explanation:
An experimental study is that in which the variables are in direct control of the researcher. He/she is in control of <em>changing or adjusting</em> them in order to reach an outcome.
Dr. Ingram <em>varied the imageability of items </em>on a list to measure the participants' recalling abilities. He is conducting an experimental study.
Let's see why the other options are not valid in this case:
- A correlational study tries to find correlations between 2 or more variables.
- In a naturalistic study the researcher observes a certain phenomenon.
- An observational study just centers on observing, there is no manipulation of variables.
